Hash Function

Advanced File Calculator is a cryptographic data hash calculation software for files. Simply drag and drop files in this calculator and hash string for the files will be displayed on the fly. Supported cryptographic hash function algorithms include CRC32 control sum, GOST hash, MD2, MD4, MD5,...

Provides efficient, effective implementations of 32- and 64-bit hash functions based on Rabin fingerprints / irreducible polynomials, in Java. Also provides integration with java.security.MessageDigest API.

jssha256 is a compact JavaScript implementation of the SHA256 secure hash function. HMAC calculation is also available. Example The following code example computes the SHA256 hash value of the string 'abc'. SHA256_init(); SHA256_write("abc"); digest = SHA256_finalize(); digest_hex =...

RIPEMD160 is a Perl module that allows you to use the RIPEMD160 Message Digest algorithm from within Perl programs. This is a BETA Version. In the future it will be located in Crypt::RIPEMD160 and not in RIPEMD160. The module is based on the implementation from Antoon Bosselaers from Katholieke...

This is a straightforward Python wrapper for ssdeep by Jesse Kornblum, which is a library for computing context triggered piecewise hashes (CTPH). Also called fuzzy hashes, CTPH can match inputs that have homologies. Such inputs have sequences of identical bytes in the same order, although bytes...

With this freeware MD5 hash values (checksums) of files can be created and compared. Because the hash function is determined by a file of any size, a fixed-length checksum. This cross-or checksum is similar to a fingerprint for each file, and almost unique. Thus, files can be compared without...
