lihata is a compact textual language which can represent a tree of lists, hashes, and tables. The syntax tries to be minimal and flexible to allow formatting a lihata file to fit the context it represents. The source release contains an event and DoM parser and helper functions for maintaining lihata trees. lihata is a convenient language for both simple and complex configuration files and text representation of data files.
FEHASHMAC is a collection of publicly known hash algorithms integrated into a command-line utility. Currently 42 hash algorithms belonging to 12 algorithm families are supported, including the five SHA-3 finalist contributions, plus HMAC for each algorithm. FEHASHMAC contains a set of over 540 known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can be directly 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 five 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, and whirl, but there are no bitwise test vectors available. FEHASHMAC can also calculate hashed message authentication codes (HMAC).
phalanx computes a digest of many buffers simultaneously, and produces a combined hash of them all. It is an initiative to provide a fast, simple, and portable alternative method to compute a checksum in a parallel fashion. It has options for I/O buffer size, hash width, number of threads, and more. It can be run single-threadedly for performance comparisons. It can check files against previously-saved sums, like "MD5sum" does. It also has a "demo" mode, to ascertain accurate operation. It is intended to be useful on large files and multicore/multiprocessor/multithreaded environments.
