WebCrypto.Hash. package. Cryptographic hash functions take arbitrary binary strings as input, and produce a random-like fixed-length output (called digest or hash value ). It is practically infeasible to derive the original input data from the digest. In other words, the cryptographic hash function is one-way ( pre-image resistance ). WebThe SHA-3 family consists of six hash functions with digests (hash values) that are 128, 224, 256, 384 or 512 bits: SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, SHAKE256.
