CipherWall Self-Decryptor
How does it works? User's data is compressed and encrypted with a key made from a passphrase and a keyfile. Then executable module is added to this archive so it becomes independent from the main program. To decrypt and decompress this archive you don't need to have the same program! You must know the passphrase or have the keyfile! Key features off the program: - high variable compression level (Deflate algorithm); - you can set different compression level for each file and directory in the archive; - strong cryptographic algorithms (Blowfish with 448-bits key in CFB mode, RC4 with 512-bits key, RC5 with 512-bits key in CFB mode and CAST-256 with 256-bits key in CFB mode); - archives are not limited in size; - files' attributes and other system information is also stored in archive; - your can use passphrase and keyfile at the same time; - your can use remote keyfile (the program will download it itself from specified URL); - modified ANSI X9.17 algorithm is used for pseudo-random numbers generation; - SHA-256 and SHA-512 algorithms are used to generate encryption key from passphrase and keyfile; - CRC32 algorithm is used for data verification; - wipe algorithms: fast, DoD-5220.22-M and Peter Gutmann's; - build-in passphrases generator; - build-in keyfiles generator.
