<h1><a name="description">DESCRIPTION</a></h1>
<p>SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function standardized
in NIST FIPS 180-4. The algorithm was designed by the United States National
Security Agency and initially published in 1995.</p>

<p>These functions return a <strong>EVP_MD</strong> structure that contains the
implementation of the symmetric cipher. See <em>EVP_MD_meth_new(3)</em> for
details of the <strong>EVP_MD</strong> structure.</p>
