Generic Hash and HMAC Program

FEHASHMAC Version 1.2.0 28.01.2012 Download The latest and all earlier releases can be downloaded from http://fehashmac.sourceforge.net 0. New Features 28.01.2012: Multiple algorithms (including HMACs) can be specified simultaneously. The data files are read only once, and all hashes are calculated in parallel. As an option, algorithm "all" expands to the list of all known algorithms, which are thus calculated in parallel for each data file or string. Likewise, algorithm "hmac-all" expands to all known HMAC algorithms. The results of the --check option and the test cases are nicely summarized. 29.03.2011: Support for the sha512-224 sha512-256 algorithms 14.04.2011: HMAC test vectors added for MD5, SHA1, RMD128, RMD160. List of algorithms is now sorted alphabetically. 13.04.2011: Support for all SHA-3 finalists: BLAKE, GROESTL, JH, KECCAK, SKEIN for 224. 256. 384, 512 bits hash length, SKEIN also for 1024 bits. They all support bitwise operation, bitwise test vectors are included (taken from the SHA-3 submissions). HMAC support upgraded to FIPS PUB 198-1 (2008), HMAC test vectors added for sha{224, 256, 384, 512}. 1. Purpose FEHASHMAC is a collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC also contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. FEHASHMAC supports bitwise hash calculation for algorithms with available bitwise test vectors. Currently this applies to the SHA algorithms: sha1, sha224, sha256, sha384, sha512, and to the SHA-3 finalists. The so-called Gillogly bitwise input has only been tested for sha1, but is also implemented in the SHA-2 hashes. Bitwise hash calculation is also supported in sha512-224, sha512-256, whirl, but there are no bitwise test vectors available. FEHASHMAC can also calculate hashed message authentication codes (HMAC) as specified in RFC 2104 and extended to arbitrary-length keys in FIPS PUB 198-1. The HMAC key can be specified as an ASCII string or as a hex string, and HMACs can be calculated for files, strings, and hex strings. To simplify usage, symbolic links with the algorithm name allow to call fehashmac without the -a option. A prepended hmac- will automatically enable HMAC mode. Hashes and HMACs of files can be verified with the --check option.
