What is a Cryptographic Hash?

When you hear the term hashing in the digital world, it's usually referring to a cryptographic hash. This is essentially the fingerprint of some data. A hash is a string of random-looking characters that uniquely identifies the data in question, much like your fingerprint identifies you. You can hash any data, for example it's just a string of characters (like a password) or checksum for files. You find the hash by running the data through a hash generator. Every time you hash the same data, you will get the exact same hash value as a result.

About HMAC Generator

The Online HMAC Generator was created to help with calculating keyed hash value using the HMAC method. Online HMAC Generator uses various algorithms such as: md2, md4, md5, sha1, sha224, sha256, sha384, sha512, ripemd128, ripemd160, ripemd256, ripemd320, whirlpool, tiger128,3, tiger160,3, tiger192,3, tiger128,4, tiger160,4, tiger192,4, snefru, snefru256, gost, adler32, crc32, crc32b, fnv132, fnv164, joaat, haval128,3, haval160,3, haval192,3, haval224,3, haval256,3, haval128,4, haval160,4, haval192,4, haval224,4, haval256,4, haval128,5, haval160,5, haval192,5, haval224,5, haval256,5.
