NAME
SHA - Perl interface to the NIST Secure Hash Algorithm
SYNOPSIS
use SHA;
$version = &SHA::sha_version;
$context = new SHA;
$context->reset();
$context->add(LIST);
$context->addfile(HANDLE);
$digest = $context->digest();
$string = $context->hexdigest();
$digest = $context->hash($string);
$string = $context->hexhash($string);
DESCRIPTION
The SHA
module is depreciated. Use Digest::SHA1
instead.
The current SHA
module is just a wrapper around the Digest::SHA1
module. It is provided so that legacy code that rely on the old interface still work. This wrapper does not support the old (and buggy) SHA-0 algorithm.
In addition to the methods provided by Digest::SHA1
this module provide the class methods SHA->hash() and SHA->hexhash() that basically do the same as the sha1() and sha1_hex() functions provided Digest::SHA1
.
The SHA->hex* methods will insert spaces between groups of 8 hex characters, while the Digest::SHA1 version of the same methods will not do this.
