Digest::SHA::PurePerl 5.45

Digest::SHA::PurePerl is a Perl implementation of SHA-1/224/256/384/512.

SYNOPSIS

In programs:

# Functional interface

use Digest::SHA::PurePerl qw(sha1 sha1_hex sha1_base64 ...);

$digest = sha1($data);
$digest = sha1_hex($data);
$digest = sha1_base64($data);

$digest = sha256($data);
$digest = sha384_hex($data);
$digest = sha512_base64($data);

# Object-oriented

use Digest::SHA::PurePerl;

$sha = Digest::SHA::PurePerl->new($alg);

$sha->add($data); # feed data into stream

$sha->addfile(*F);
$sha->addfile($filename);

$sha->add_bits($bits);
$sha->add_bits($data, $nbits);

$sha_copy = $sha->clone; # if needed, make copy of
$sha->dump($file); # current digest state,
$sha->load($file); # or save it on disk

$digest = $sha->digest; # compute digest
$digest = $sha->hexdigest;
$digest = $sha->b64digest;

From the command line:

$ shasum files

$ shasum --help

SYNOPSIS (HMAC-SHA)

# Functional interface only

use Digest::SHA::PurePerl qw(hmac_sha1 hmac_sha1_hex ...);

$digest = hmac_sha1($data, $key);
$digest = hmac_sha224_hex($data, $key);
$digest = hmac_sha256_base64($data, $key);

ABSTRACT

Digest::SHA::PurePerl is a complete implementation of the NIST Secure Hash Standard. It gives Perl programmers a convenient way to calculate SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512 message digests. The module can handle all types of input, including partial-byte data.
