NAME

Digest::BMW - Perl interface to the Blue Midnight Wish digest algorithm

SYNOPSIS

    # Functional interface
    use Digest::BMW qw(bmw_256 bmw_256_hex bmw_256_base64);

    $digest = bmw_256($data);
    $digest = bmw_256_hex($data);
    $digest = bmw_256_base64($data);

    # Object-oriented interface
    use Digest::BMW;

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

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

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

DESCRIPTION

The Digest::BMW module provides an interface to the Blue Midnight Wish message digest algorithm. Blue Midgnight Wish is a candidate in the NIST SHA-3 competition.

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

FUNCTIONS

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

bmw_224($data, ...)

bmw_256($data, ...)

bmw_384($data, ...)

bmw_512($data, ...)

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

bmw_224_hex($data, ...)

bmw_256_hex($data, ...)

bmw_384_hex($data, ...)

bmw_512_hex($data, ...)

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

bmw_224_base64($data, ...)

bmw_256_base64($data, ...)

bmw_384_base64($data, ...)

bmw_512_base64($data, ...)

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

METHODS

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

new

    $bmw = Digest::BMW->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.
