(Explanation 02)

Display the type of desired files

       Click here to display, in the shutter of files exploration (on the right), only the type of desired files.

       For example, if you wish to display only the files whose name ends in '.doc', click and select '*.doc'.
       So, when you select a folder, it will be only the files whose extension is '.doc' that will display in the shutter of files exploration, and all the other files will remain invisible.

       For example, if you want to encrypt all the files in a folder which have the extension '.zip', select the line '*.zip' in this list of filters in order to see, in the shutter of files exploration, only these files ending in '.zip'. Then you can all select them to encrypt them.

       Here are the extensions which this filters list contains: (*.*), (*.aif), (*.avi), (*.bmp), (*.com), (*.ctt), (*.dat), (*.doc), (*.exe), (*.gif), (*.hlp), (*.htm), (*.html), (*.img), (*.inf), (*.ini), (*.jfif), (*.jif), (*.jpe), (*.jpeg), (*.jpg), (*.m4e), (*.mht), (*.mid), (*.midi), (*.mov), (*.mp1), (*.mp2), (*.mp3), (*.mp4), (*.mpeg), (*.mpg), (*.png), (*.ppt), (*.psp), (*.psw), (*.r1m), (*.raw), (*.rec), (*.reg), (*.rmi), (*.rtf), (*.snd), (*.tar), (*.taz), (*.tga), (*.tif), (*.tmp), (*.tra), (*.ttc), (*.ttf), (*.txt), (*.wav), (*.wmv), (*.wri), (*.zip). They are the filters allowing you to display only the files with the extension selected.

       To display all the types of files, select '*.*' in this list.

(Explanation 03)

Select a folder

       Click here to select the folder from which you wish to display the file(s) you want to encrypt, decrypt, edit, open, etc. .

       The files belonging to that folder will display in the shutter of files exploration on the right.

(Explanation 04)

Shutter of files exploration

       The 1st column of this exploration window (the column 'Name') indicates the name of each file.

       The 2nd column of this exploration window (the column 'Size') indicates the size in Kilo bytes (KB) of each file. One character is equivalent to 1 byte, and 1024 bytes are equivalent to 1 Kilo bytes (KB).

       The 3rd column of this exploration window (the column 'Status') indicates whether the file (on its same line) is 'Encrypted' or 'Non-encrypted'.

       The 4th column of this exploration window (the column 'Date of modification') indicates the date and the hour when the file was modified the last time.

       The 5th column of this window of exploration (the column 'Read only') indicates whether a file is protected against the writing. This option is selected via the menu line "Attribute 'Read-only' " which is displayed by a right click of the mouse on a file.

_____________

       Note that the files, which are displayed in this window, are those whose extension is selected in the box just on left of the word 'Name'; so, just to the right of the box where the drive is selected.

       For example, if you select '*.*' this means that all files display, regardless of their extension.

       However, if you select '*.txt', only files with the extension (end of the file name) '.txt' will be displayed. This is true for all extensions of the list.

       The path file that is selected displays just below in the blue background box. This address of the selected source file can also be used in the tab 'Raw data' via the button 'Display raw data from the source file', and in the tabs 'Text/e-mail', 'Video/picture/audio', 'Internet' and 'Intuitive' via the button 'Open the source file'.

       The exploration shutter in top is used to select a source file (ie, the file from which you crypt, decrypt, display, edit, etc.).

       The exploration shutter in bottom is used to select a destination filename (ie, the file name to be used to save your changes, for example, the result of encryption, decryption, edition, etc.).

       When you click the right mouse button on a file, a menu appears with the following lines: 'Encrypt...', 'Decrypt...', 'Cut', 'Copy', 'Delete', 'Open' and ' Attribute 'Read-only' '.
       However, in the destination window (in bottom), the first two lines of command 'Encrypt...' and 'Decrypt...' will not appear if one of two lines of command 'Identical source and destination folders' and 'Identical source and destination files' is disabled in the 'File' menu at the top.

* * * * *
'Encrypt...'

       In the menu that appears via a right-click on a file, if you click on the command line 'Encrypt ...', you will encrypt this file during an indicator shows the progress of treatment in progress; but before, you must have written a personal key in the box provided for that purpose (in top), if not your file will not be encrypted.
       If you want proof that the recipient has received your file (or your data), then you have the option to include an acknowledgement of receipt and an acknowledgement key in your file (or in your data) when you encrypt . To do this, click on 'Options' menu and then on the line 'Encrypt including an acknowledgement of receipt'. This will display two lines just below the first white box at the top.
       If the recipient uses the right personal key (the same one as you used to encrypt) to decrypt your file, then the acknowledgement of receipt is firstly decrypted and a window appears revealing this acknowledgement of receipt (to him) that you have encrypted in the past, and he must send it to you to receive in return from you an acknowledgement key which he must then enter in this same window in order to be able to begin decrypting. So, when you receive from him the acknowledgement of receipt, this is the proof that he is the recipient who received your file (your data) and who is in possession of your file.
       So you know that only the recipient was able to decrypt the acknowledgement of receipt via his personal key, and this is why you send to him in return the acknowledgement key so that he writes it (or copies it) in the same small window to allow him to continue the operation which decrypts the file (or data) in question; because without the acknowledgement key he will not be able to decrypt it. Click with '?' on these lines to display the explanation of these 2 lines.

       When you encrypt a file by clicking on the command line 'Encrypt...', only this file will be encrypted and without being displayed in AllCrypter.

       You can also encrypt a file by clicking the button 'Encrypt' on the top, left corner of AllCrypter.

       Note that several selected files can be encrypted at once.

       Note that at the end of the process of encryption, a big button labeled 'Temporary file: cleaning and removal in progress... Click here to remove without cleaning.' is displayed during the automation of cleaning and removal of the temporary file which has been just created. To save time in the case of a very large file, you can remove this temporary file without cleaning it, by clicking on this big button.

       If, in the upper window of files exploration, you double-click a non-encrypted compatible file, that file will not be crypted but AllCrypter opens it automatically either in the 3rd, 4th or 5th tab.

       In this way, the majority of the files are displayed in the 3rd tab ('Text/e-mail') or 4th tab ('Video/picture/audio'); but files with the extension '.mht', '.htm' or '.html' are directed in the window of the 5th tab ('Internet').
- For example, the text (txt, doc, etc.) will be displayed in the window of the 3rd tab ('Text/e-mail').
- A photo or a picture (bmp, jpg, gif, etc.) will be displayed in the window of the 4th tab ('Video/picture/audio').
- A video (mpg, avi, wmv, etc.) will be loaded into the window of the 4th tab ('Video/picture/audio') and its reading will begin automatically.
- A sound file (mp3, wav, mid, etc.) will be loaded into the window of the 4th tab ('Video/picture/audio') and start reading automatically.
- An Internet or HTML file (mht, htm, html, etc.) will be displayed in the window of the 5th tab ('Internet').
- A file that cannot be read, listened, etc. with AllCrypter it would be opened in the window of the 3rd tab ('Text/e-mail').

* * * * *
'Decrypt...'

       In the menu that appears via a right-click on a file, if you click on the command line 'Decrypt...', this file will be decrypted and an indicator will indicate the progression of treatment in progress; but before it is necessary to write the right key (the right characters) in the box provided for that purpose (top). The key needed to decrypt a file must be the same one that has served to encrypt, if not your file can not be decrypted.

       When you decrypt a file in this way, only this file will be decrypted and that without being displayed in AllCrypter.

       You can also decrypt a file by clicking the button 'Decrypt' on the top, the 2nd button from the left in the toolbar of AllCrypter.

       Note that several files selected simultaneously can be decrypted.

       Note that at the end of the decryption process, a big button labeled 'Temporary file: cleaning and removal in progress... Click here to remove without cleaning.' is displayed during the automation of cleaning and removal of the temporary file which has been just created. To save time in the case of a very large file, you can remove this temporary file without cleaning it, by clicking on this big button.

       When you click to begin to decrypt your file, if you use the right personal key (the same one as the sender used to encrypt) and if the sender had included into this file an acknowledgement of receipt during encryption in the past (the acknowledgement of receipt encrypted with the data) then the acknowledgement of receipt is firstly decrypted and a small window (a dialog box) appears revealing to you this acknowledgement of receipt now decrypted by you. You must send this acknowledgement of receipt to the sender to receive in return from him an acknowledgement key which you must then enter in this same dialog box in order to be able to begin decrypting of your file (your data).

       So, when the sender receives from you the acknowledgement of receipt, this is the proof for him that you are the recipient who received his file (these data) and that you are in possession of his file. So he knows that only you, the recipient was able to decrypt this acknowledgement of receipt via your personal key, and this is why he sends to you in return the acknowledgement key so that you write it (or copie it) in the same small window (the same dialog box) to allow you to continue the operation which decrypts the file (or data) in question; because without this acknowledgement key you will not be able to decrypt it.

       If, in the upper window of files exploration, you double-click an already encrypted compatible file, that file itself will not be decrypted but only the data of this file will be decrypted in temporary memory, and all which is decrypted is automatically displayed in the 3rd, 4th or 5th tab.

       In this way, most of the files display in the 3rd tab ('Text/e-mail') or in the 4th tab ('Video/picture/audio'), but files with the extension '.mht', '.htm' or '.html' are directed in the window of the 5th tab ('Internet').

- For example, if the decrypted result is text (txt, doc, etc.) it will be displayed in the window of the 3rd tab ('Text/e-mail').
- If this is a photo or picture (bmp, jpg, gif, etc.) it will be displayed in the window of the 4th tab ('Video/picture/audio').
- If it's a video (mpg, avi, wmv, etc.) it will be loaded into the window of the 4th tab and its playing will begin automatically.
- If this is a sound file (MP3, WAV, MID, etc.) it will be loaded into the window of the 4th tab and its playing will begin automatically.
- If this is an Internet or HTML file (mht, htm, html, etc.) it will be displayed in the window of the 5th tab ('Internet').
- If this file cannot be viewed, listened, etc. with AllCrypter, it should open in the window of the 3rd tab ('Text/e-mail').

       Noter que le texte ouvert dans le 3e onglet ('Texte/courriel') peut être modifié pour ensuite être crypté de nouveau via la commande 'Crypter et enregistrer dans le dernier fichier source ouvert ici' du menu contextuel afin d'enregistrer automatiquement ses modifications dans le même fichier d'origine.
       Note that the text (for example, your 'private diary') which opens in the 3rd tab ('Text/e-mail') can be modified to be encrypted again via the 'Encrypt and save into last source file opened here' command of the contextual menu so that in this way these changes are automatically saved in the same original file.

* * * * *
'Cut'

       By clicking on the command line 'Cut', the name or names of the selected files are copied and retained in random access memory (in RAM).

       Thereafter, in the shutter of files exploration, in the folder where you click on the command line 'Paste' (via the menu that appears via a right click of the mouse on the right of any file) these files are paste there; at the same time, these files are removed from the folder where they were cut.

* * * * *
'Copy'

       By clicking on the command line 'Copy', the name or names of the selected files are copied and retained in memory (in RAM).

       Thereafter, in the shutter of files exploration, on the right, in the folder where you click on the command line 'Paste' (via the menu that appears via a right click of the mouse on the right of any file name) these files are paste there.

* * * * *
'Delete'

       By clicking on the command line 'Delete', the selected file or selected files are removed from their folder.
       However, these files can be recovered from the trash of Windows.

* * * * *
'Open'

       If you click on the command line 'Open' the command is given to Windows to open your file with the software which is associated (by Windows) to the extension of this file (ie, the last 3 characters of the name, characters after the last dot '.'). But if the file name has no extension, it could not be open in this way.

* * * * *
'Attribute 'Read-only''

       If you click on the command line ' Attribute 'Read-only' ' this marks the file so that it is impossible to make changes there. To make it possible once again to make changes, click again on this same command line.

_____________

       If you click the right mouse button on the right of a file name, a menu appears with the following commands lines: 'New file', 'New folder', 'Refresh' and 'Paste'.

* * * * *
'New file'

       By clicking on the command line 'New file', a window appears asking you to write the new file name to be created. Then, by clicking on button 'OK', this file is created in the folder.

* * * * *
'New folder'

       By clicking on the command line 'New Folder', a window appears asking you to write the name of the new folder to be created. Then, by clicking 'OK', this folder is created in the folder already opened in the shutter of folders exploration (on the left).

* * * * *
'Refresh'

       By clicking on the command line 'Refresh', AllCrypter makes a new reading of all files within that folder.

       For example, this is useful after the creation of a new file via another software. Thus, the list of files in the folder is updated at the screen.

* * * * *
'Paste'

       The command line 'Paste' is used to paste the file or files whose names were previously placed in memory via the 'Copy' or 'Cut' command (in AllCrypter only) of the menu that appears by a right mouse clicking on one or more files.

       By the same time, if these files were previously cut, they will be removed from the folder where they were cut.
       But if these files were previously copied, in this case they will not be removed from the folder where they were copied.

       For other explanations, with the question mark (?), click on one of the following menus: 'File', 'View', 'Options' or 'Help'.

(Explanation 05)

Indicator of the selected source file.

       This label indicates the name of the source file which is selected and its access path.

       In other tabs, when you use the source file name selected in the 1st tab, this is the one that appears here.

(Explanation 06)

Indicator of information
and
box for personal key

       It is in this white box (at the top) that you must write your personal key (which must always remain secret, known only to you and the recipient), which is used, in some ways, to encrypt or decrypt your data.
       So, before clicking on the button 'Encrypt' or the button 'Decrypt', first you must write your personal key here.

       Your personal key is never used to encrypt the data on your file, but only two keys of session which are automatically created from your personal key. Whenever you encrypt a file, two keys of session, each one of the same size as your personal key, are created from a mixture of your personal key, peuso-random data and initially random data (created from random).
       Even if you encrypt the same file several times from the same personal key, the two keys of session which are automatically created with each encryption are never the same ones; with the result that the same file encrypted 1000 times will always be encrypted differently from the one to another; there are not two of them which will be encrypted identically even if you always use the same personal key.

       Each character in the 2 keys of sessions created from your personal key is used for calculations of encryption as if each of these characters was part of the internal code. So, each character of these two keys of session produces different values in the calculations.
       This means that even if one of these characters of two session key is changed then it changes not only the calculations made on a specific data in your file to be encrypted, but also on all data in the rest of the file.
       To give an idea, even by considering a simple inversion of two characters in only one key of session, there would be nevertheless a change of values in the calculations for each data throughout the rest of the file (however the modification of the keys of session is not limited to a simple inversion of characters, but the changes occur on all the characters).
        Each of calculations for each character is much more complicated than described here (refer to the commentary on 'Algo HR' on Internet site ' www.allcrypter.com ').

       AllCrypter uses (from the version 3.0) the Algorithm RH (Algo RH ; in french: 'Algorithme RH'). It has a logic of specific calculation for it (in relation to the keys of session, etc.); the objective being that even a programmer, having the codes of AllCrypter and the algorithm in front of him (the 2 are already made public on the website ' www.allcrypter.com ' at the section treating of the algo RH), is unable, no matter the analysis, to decrypt a file encrypted by you; the value of each character of the keys of session is used as part of the code on the calculations that are made.

       So, for each encryption which this algorithm performs, 2 initial keys of session ('sia' and 'sib') are created from random and are used only once; with each encryption, these 2 keys are different. These 2 initial keys of session are created same size as the personal key ('k') of the user; and progressively with the process of the encryption, these two initial keys of session are prolonged until a size larger than the size of the data to encrypt.
       Only the final part of these 2 keys of session is preserved (same size of your personal key) to be encrypted (with other special information contained in 'InfoS') via the personal key ('k', which is a known secrecy only of the sender <you> and the recipient <the other>) to be part of cryptogram.
       For the decryption, your personal key ('k') is used to decrypt the 2 final keys of session which in their turn take the changing to continue the decryption of the cryptogram. The two final keys of session ('sfa' and 'sfb') are always the same size as the two initial keys of session ('sia' and 'sib') and the personal key ('k') of the user. The complete size of the keys of session (automatically created via the algorithm) exceeds the size of the encrypted data, but it is the final part (which exceeds the size of the data) which is kept in the cryptogram.

* * *

       The blue gray label (at the top) in the interface of AllCrypter indicates the number of bits via which you encrypt or decrypt your data. The number of possible combinations on the written personal key is also displayed, ie, the number of possible maximum attempts (to write personal different keys) that a person would have to make before finding the right key.

       By comparison, the speed of one number per second, a person would take approximately 100 years to count before reaching the number three billion (3000000000); imagine now that number multiplied several times by itself.
       For example, if one takes a simple personal key of 16 characters, taking into account that there are 256 possibilities per character, there will be a level of 128 bits encryption, which offers a possibility of approximately 3.4+38 different keys, i.e. the number 3.4 whose point is moved to the right of 38 digits, so 340000000000000000000000000000000000000 different keys.
       This level of encryption of 128 bits is used by many financial institutions (banks, etc.) for their transactions on the Internet.
       Even Microsoft, in its version 7 of Internet Explorer, offers to us this level of 128 bits encryption. To verify this, in Internet Explorer, click the question mark ('?') (or 'Help'), then click on the line 'About Internet Explorer', and finally, in the window which opens, read the line that begin with 'Cipher Strength'.

       Actually, it would be impossible to try all possible combinations to find a key knowing that it could take centuries or millennia with a computer before finding, in an automatic way, your key, even with a processor given rhythm to several million cycles a second. More the key contains characters, more it is difficult to find it.

       In AllCrypter, you can write a key ranging from 16 characters to a maximum of 512 characters. A key of 512 characters offers a level of encryption of 4096 bits.
       The possible number of combinations using 4096 bits gives a number with a length of 1234 digits. This approximate number is the number one plus 1233 zeros after this number one; in other words 10 ... until you added 1233 zeros after the number one, so 1 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 different keys.

       It is noteworthy that the encryption by AllCrypter is an encryption of high quality. Unlike some encryption software that transforms a character always by a same other character, AllCrypter does not proceed thus. However, AllCrypter can help you (via the 6th tab: 'Intuitif') to decrypt that other type of encryption that transforms a single character always by a same other character (AllCrypter does not encrypts its own data in this way, because to encrypt, AllCrypter uses a different logic via a high quality algorithm).

       AllCrypter is created for the purpose it is impossible without your personal key, even to its designer (the programmer), to decrypt your encrypted data with AllCrypter. AllCrypter does not contain a go-anywhere key that could decrypt your data. The police authorities do not therefore have a go-anywhere key to decrypt your data. If you lose your personal key that you used to encrypt your file, you also lose the capacity to decrypt this same file.
       You are therefore advised to take note each one of your keys in order not to forget them. AllCrypter has an option allowing you to automatically save into a file your personal keys, your acknowledgements of receipt and your acknowledgement keys. AllCrypter can thus automatically save them (all the keys) into the file 'Keys and acknowledgements of receipt.txt' in the folder 'Keys' of the folder 'AllCrypter', when the command line <Save the acknowledgements of receipt and the keys into the folder 'Keys'> is activated (with a check mark); thereafter, you can encrypt this file (the keys file) with always a same other personal key specifically used for this purpose.

* * *

       During the encryption and decryption, a progress bar appears indicating visually the progress of the accomplished implementation. The number of seconds remaining estimated and the number of seconds elapsed display.

       Note that when you decrypt, AllCrypter automatically recognizes with which version of AllCrypter the data have previously been encrypted, and it proceeds to the decryption.

       An identifying code (generated via different calculations from the personal key) is integrated in the part 'InfoS' (encrypted) of the cryptogram. The advantage that this identifying code is inserted with your data in the cryptogram is, that when you try to decrypt your data with the wrong personal key, AllCrypter will not begin the process of decryption and it will indicate to you that you did not write the right personal key; otherwise your data would be badly decrypted and might be lost forever.

(Explanation 07)

Indicator of the destination file (selected or created)

       This label indicates the name of the destination file (and its path) which is selected in the exploration shutter in bottom (destination), or which one you write. This is the destination file name under which you save your encrypted data, decrypted data, edited data, etc.

       In other tabs, when you use the destination file name selected in the 1st tab, this is the one that displays here.

(Explanation 18)

Select a directory (folder)

       Click here to select the folder where you want to save the modifications of encrypted, decrypted or edited data.

       The names of the files belonging to that folder display in the shutter of files exploration on the right.
