SHA-1 (The Secure Hash Algorithm) is a cryptographic hash function (or message digest algorithm) designed by the National Security Agency (NSA) and published by the United States Government. It produces an 160 bit hash value from a string of a maximum of 2^64 bits. It was released in support of the Government's attempt to control the export of quality encryption. It is a part of the [Digital Signature Standard]?, also published by the US Government, which was intended to provide high quality authentication without the possibility of encryption. It turned out that encryption was possible, so the intended result was 'self-thwarted'.
