WebApr 21, 2024 · Hashing data is a common practice in computer science and is used for several different purposes. Examples include cryptography, compression, checksum generation, and data indexing. Hashing is a natural fit for cryptography because it masks the original data with another value. Webcryptography uses multiple hash functions to secure data. Some of the most popular cryptographic hashes include the following: Secure Hash Algorithm 1 ( SHA-1) Secure Hash Algorithm 2 (SHA-2) Secure Hash Algorithm 3 ( SHA-3) MD2 MD4 MD5 Message-digest hash functions like MD2, MD4 and MD5 help hash digital signatures. flownity
