14 SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function
15 standardized in NIST FIPS 180-4. The algorithm was designed by the
16 United States National Security Agency and initially published in 1995.

23 These functions return a EVP_MD structure that contains the
24 implementation of the symmetric cipher. See EVP_MD_meth_new(3) for
25 details of the EVP_MD structure.
