During mid-70s, IBM Research developed Data Encryption Standard (DES), block cipher cryptography. DES is a widely-used method of data encryption. Since DES was adopted as a federal standard in 1977, it has served as the cryptographic standard for 25 years and enables secure communications and commerce. In 2002, Don Coppersmith, who was one of the research team members developed DES, won the RSA Security Award for Mathematics for his work in the field of cryptography.

CRYPTANALYSIS OF BLOCK CIPHER - PART 1-Prof Amr M Youssef- INSPEM UPM

TrueCrack is a brute-force password cracker for TrueCrypt (Copyrigth) volume files. It works on Linux and it is optimized with Nvidia Cuda technology. It works with cripted volumes with the following algorithms: PBKDF2 (defined in PKCS5 v2.0) based on RIPEMD160 Key derivation function. XTS block cipher mode of operation used for hard disk encryption based on AES.
