325 Digest::SHA is a complete implementation of the NIST Secure Hash Standard.
332 Digest::SHA is written in C for speed.  If your platform lacks a
334 slower) L<Digest::SHA::PurePerl> module.
337 in CPAN's L<Digest> module.  So, if your applications currently
338 use L<Digest::MD5> and you'd prefer the stronger security of SHA,
345 	use Digest::SHA qw(sha256_hex);
354 	$state = Digest::SHA->new(256);
367 	use Digest::SHA;
369 	$sha = Digest::SHA->new(1)->add_bits($bits);
383 	use Digest::SHA;
384 	print Digest::SHA->new->add("Shaw" x 1962)->getstate;
386 As an added convenience, the Digest::SHA module offers routines to
394 	use Digest::SHA qw(hmac_sha256_hex);
