NAME
    Digest::ED2K - Calculate ED2K digests

SYNOPSIS
            # Functional
            use Digest::ED2K qw(ed2k ed2k_hex ed2k_base64);

            my $digest = ed2k $data;
            my $hexdigest = ed2k_hex $data
            my $base64_digest = ed2k_base64 $data;

            # Object Oriented
            use Digest::ED2K;

            my $ctx = Digest::ED2K->new;

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

            my $digest = $ctx->digest;
            my $hexdigest = $ctx->hexdigest;
            my $base64_digest = $ctx->b64digest;

DESCRIPTION
    Digest::ED2K progressively calculates ED2K digests of data.

FUNCTIONS
    Digest::ED2K implements the following functions.

  `ed2k'
            my $digest = ed2k $bytes, ...;

    Generate binary ED2K digest for string.

  `ed2k_hex'
            my $hexdigest = ed2k_hex $bytes, ...;

    Generate hex ED2K digest for string.

  `ed2k_base64'
            my $base64_digest = ed2k_base64 $bytes, ...;

    Generate base64 ED2K digest for string.

METHODS
    Digest::ED2K inherits all methods from Digest::base (See Digest for
    documentation) and implements the following new ones.

  `new'
            my $ctx = Digest->new('ED2K');
            my $ctx = Digest::ED2K->new;

    Construct a new Digest::ED2K object.

  `add'
            $ctx = $ctx->add($bytes, ...);

    Append binary data.

  `clone'
            my $ctx_clone = $ctx->clone;

    Clone this message context.

  `digest'
            my $digest = $ctx->digest;

    Binary ED2K digest for this message context.
