NAME ^

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

SYNOPSIS ^

    # Functional interface
    use Digest::BLAKE qw(blake_256 blake_256_hex blake_256_base64);

    $digest = blake_256($data);
    $digest = blake_256_hex($data);
    $digest = blake_256_base64($data);

    # Object-oriented interface
    use Digest::BLAKE;

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

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

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

DESCRIPTION ^

The Digest::BLAKE module provides an interface to the BLAKE message digest algorithm. BLAKE 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::BLAKE module. None of these functions are exported by default.

blake_224($data, ...)

blake_256($data, ...)

blake_384($data, ...)

blake_512($data, ...)

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

blake_224_hex($data, ...)

blake_256_hex($data, ...)

blake_384_hex($data, ...)

blake_512_hex($data, ...)

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

blake_224_base64($data, ...)

blake_256_base64($data, ...)

blake_384_base64($data, ...)

blake_512_base64($data, ...)

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

METHODS ^

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

new

    $blake = Digest::BLAKE->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.
