+EVP_sha1
+- SHA-1 For EVP
+
+=head1 SYNOPSIS
+
+ #include <openssl/evp.h>
+
+ const EVP_MD *EVP_sha1(void);
+
+=head1 DESCRIPTION
+
+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.

+
+The SHA-1 algorithm which produces a 160-bit output from a given input.

+
+These functions return a B<EVP_MD> structure that contains the
+implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
+details of the B<EVP_MD> structure.
