WebSkein is a cryptographic hash function and one of five finalists in the NIST hash function competition.Entered as a candidate to become the SHA-3 standard, the successor of SHA-1 and SHA-2, it ultimately lost to NIST hash candidate Keccak.. The name Skein refers to how the Skein function intertwines the input, similar to a skein of yarn.
