If B<md> is NULL, the digest -is placed in a static array. - -The following functions may be used if the message is not completely -stored in memory: - -SHA1_Init() initializes a B<SHA_CTX> structure. - -SHA1_Update() can be called repeatedly with chunks of the message to -be hashed (B<len> bytes at B<data>). - -SHA1_Final() places the message digest in B<md>, which must have space -for SHA_DIGEST_LENGTH == 20 bytes of output, and erases the B<SHA_CTX>. - -Applications should use the higher level functions -L<EVP_DigestInit(3)|EVP_DigestInit(3)> -etc. instead of calling the hash functions directly. - -The predecessor of SHA-1, SHA, is also implemented, but it should be -used only when backward compatibility is required. - -=head1 RETURN VALUES - -SHA1() returns a pointer to the hash value. - -SHA1_Init(), SHA1_Update() and SHA1_Final() do not return values. - -=head1 CONFORMING TO - -SHA: US Federal Information Processing Standard FIPS PUB 180 (Secure Hash -Standard), -SHA-1: US Federal Information Processing Standard FIPS PUB 180-1 (Secure Hash -Standard), -ANSI X9.30 - -=head1 SEE ALSO - -L<ripemd(3)|ripemd(3)>, L<hmac(3)|hmac(3)>, L<EVP_DigestInit(3)|EVP_DigestInit(3)> - -=head1 HISTORY - -SHA1(), SHA1_Init(), SHA1_Update() and SHA1_Final() are available in all -versions of SSLeay and OpenSSL. - -=cut |
