NAME

Digest::Shabal - Perl interface to the Shabal digest algorithm

SYNOPSIS

    # Functional interface
    use Digest::Shabal qw(shabal_256 shabal_256_hex shabal_256_base64);

    $digest = shabal_256($data);
    $digest = shabal_256_hex($data);
    $digest = shabal_256_base64($data);

    # Object-oriented interface
    use Digest::Shabal;

    $ctx = Digest::Shabal->new(256);

    $ctx->add($data);
    $ctx->addfile(*FILE);

    $digest = $ctx->digest;
    $digest = $ctx->hexdigest;
    $digest = $ctx->b64digest;

DESCRIPTION

The Digest::Shabal module provides an interface to the Shabal message digest algorithm. Shabal was a candidate in the NIST SHA-3 competition but did progress beyond round 2.

This interface follows the conventions set forth by the Digest module.

FUNCTIONS

The following functions are provided by the Digest::Shabal module. None of these functions are exported by default.

shabal_224($data, ...)

shabal_256($data, ...)

shabal_384($data, ...)

shabal_512($data, ...)

Logically joins the arguments into a single string, and returns its Shabal digest encoded as a binary string.

shabal_224_hex($data, ...)

shabal_256_hex($data, ...)

shabal_384_hex($data, ...)

shabal_512_hex($data, ...)

Logically joins the arguments into a single string, and returns its Shabal digest encoded as a hexadecimal string.

shabal_224_base64($data, ...)

shabal_256_base64($data, ...)

shabal_384_base64($data, ...)

shabal_512_base64($data, ...)

Logically joins the arguments into a single string, and returns its Shabal digest encoded as a Base64 string, without any trailing padding.

METHODS

The object-oriented interface to Digest::Shabal is identical to that described by Digest, except for the following:

new

    $shabal = Digest::Shabal->new(256)

The constructor requires the algorithm to be specified. It must be one of: 224, 256, 384, 512.

algorithm

hashsize

Returns the algorithm used by the object.
