CPython implementation … WebSHA-1 (Secure Hash Algorithm) is a cryptographic hash function with a 160 bit output. SHA1 () computes the SHA-1 message digest of the n bytes at d and places it in md (which must have space for SHA_DIGEST_LENGTH == 20 bytes of output). If md is NULL, the digest is placed in a static array. Note: setting md to NULL is not thread safe. how many inches of rain for snow
