WebThe Ultimate Hash Algorithm Comparison: MD5 vs. SHA-1 vs. SHA-2 vs. SHA-3. Before we start, let’s define what a hash algorithm is in a few simple words: A hash is a one-way mathematical function (i.e., it can’t be reverse engineered) that converts the input into an unreadable data string output of a set length. For example, you could take the phrase … WebThe Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".
