A tiny program to encrypt and decrypt your data. MiCry is an innovative way for handling your data privacy an security due it's new way to encrypt and decrypt data where the method used by encrypt the data became an "algorithm sequence" that sound like an another password. In fact a brute force attack for decrypt data before to break your password it should detect the agorithm sequence.

You can mix up to 22 different algorithms but for encrease the complessity you can repeat the same algorithm as you like using AES encrytion, data compression and some specials method.

MiCry consists of two executable: micry.exe that provides the GUI and micryc.exe for the CONSOLE subsystem.

Using MiCry
You should start MiCry from command prompt or from another program or batch.

Command Line Options
MiCry supports the following command-line options:

usage: micry.exe [/e|/d] [/a:AlgoSeq] [/b] [/fKeyFile] [/n] [/o] [/p] [/q] [/v] FileName Password
/e Encrypt the data (default action).
/d Decrypt previously encrypted data.
/a:AlgoSeq Algorithms sequence to perform, can be one or more of following:
* a Compress/Uncompress data, require ZLIB1.DLL.
* b Fast variant of AES Rijndael algorithm.
* c Fast variant of AES Serpent algorithm.
* d AES Twofish algorithm.
* e RC4 algorithm.
* f SSCA 1 algorithm.
* g SSCA 2 algorithm.
* h SSCA 3 algorithm.
* i SSCA 4 algorithm.
* j AES Rijndael Algorithm.
* k SSCA 5 algorithm.
* l SSCA 6 algorithm.
* m SSCA 7 algorithm.
* n SSCA 8 algorithm.
* o SSCA 9 algorithm.
* p SSCA 10 algorithm.
* q AES Serpent algorithm.
* r SSCA 11 algorithm.
* s Skipjack algorithm.
* t Ceasar shift algorithm.
* u TEA algorithm.
* v SSCA 12 algorithm.

/b Burn (overwrite and delete) the original file (valid only with the /n option).
/fKeyFile Key file to use for encrypt or decrypt data.
/n Create a new output file and leave the original one on disk putting the 'x' or 'y' character after the extension.
/o Automatically opens the file after that it has been decrypted (valid only with the /d option).
/p Use also the full path of KeyFile as key, this means that the file and the path must exist in same location for decrypt successfully the data.
/q Runs in quiete mode.
/v Use the virtual keyboard for bypass keyloggers (Runs Micry GUI).

FileName: File(s) to encrypt or decrypt (wildcard chars are allowed).
Password: Password for encrypt or decrypt the file.

EXAMPLES:
For encrypt:
micry /e /a:abcdefgspolska MyAccount.xls 1234567890 /fReadMe.txt /q
For decrypt:
micry /d /a:abcdefgspolska MyAccount.xls 1234567890 /fReadMe.txt /q

Return Value
MiCry returns non zero value if fails, otherwise returns zero. Please keep in mind (when you decrypt data) that the return value doesn't mean that data are decrypted but only that the internal work was done without errors.

Note
Before to encrypt important data always make sure you have a backup copy of them because in case of error it will be impossible to recover the original data.

With the /o option, the file will be opened using the ShellExecuteEx() API and if the file type is unknow it will be opened with notepad.exe.

The license of this software is Freeware, you can free download and free use this file encryption software.
