%description
Digest::SHA::PurePerl is written entirely in Perl.  If your platform
has a C compiler, you should install the functionally equivalent
(but much faster) Digest::SHA module.

The programming interface is easy to use: it's the same one found
in CPAN's Digest module.  So, if your applications currently
use Digest::MD5 and you'd prefer the stronger security of SHA,
it's a simple matter to convert them.

The interface provides two ways to calculate digests:  all-at-once,
or in stages.  To illustrate, the following short program computes
the SHA-256 digest of "hello world" using each approach:

	use Digest::SHA::PurePerl qw(sha256_hex);

	$data = "hello world";
	@frags = split(//, $data);

	# all-at-once (Functional style)
	$digest1 = sha256_hex($data);

	# in-stages (OOP style)
	$state = Digest::SHA::PurePerl->new(256);
	for (@frags) { $state->add($_) }
	$digest2 = $state->hexdigest;

	print $digest1 eq $digest2 ?
		"whew!\n" : "oops!\n";

To calculate the digest of an n-bit message where *n* is not a
multiple of 8, use the *add_bits()* method.  For example, consider
the 446-bit message consisting of the bit-string "110" repeated
148 times, followed by "11".  Here's how to display its SHA-1
digest:

	use Digest::SHA::PurePerl;
	$bits = "110" x 148 . "11";
	$sha = Digest::SHA::PurePerl->new(1)->add_bits($bits);
	print $sha->hexdigest, "\n";

Note that for larger bit-strings, it's more efficient to use the
two-argument version *add_bits($data, $nbits)*, where *$data* is
in the customary packed binary format used for Perl strings.

The module also lets you save intermediate SHA states to disk, or
display them on standard output.  The *dump()* method generates
portable, human-readable text describing the current state of
computation.  You can subsequently retrieve the file with *load()*
to resume where the calculation left off.

To see what a state description looks like, just run the following:

	use Digest::SHA::PurePerl;
	Digest::SHA::PurePerl->new->add("Shaw" x 1962)->dump;

As an added convenience, the Digest::SHA::PurePerl module offers
routines to calculate keyed hashes using the HMAC-SHA-1/224/256/384/512
algorithms.  These services exist in functional form only, and
mimic the style and behavior of the *sha()*, *sha_hex()*, and
*sha_base64()* functions.

	# Test vector from draft-ietf-ipsec-ciph-sha-256-01.txt

	use Digest::SHA::PurePerl qw(hmac_sha256_hex);
	print hmac_sha256_hex("Hi There", chr(0x0b) x 32), "\n";
