NAME

Net::DNS::SEC::Digest - Message Digest Algorithms

SYNOPSIS

    require Net::DNS::SEC::Digest;

    $object = Net::DNS::SEC::Digest::SHA->new(256);
    $object->add($text);
    $object->add($more);
    $digest = $object->digest;

DESCRIPTION

Interface package providing access to the message digest algorithm implementations within the OpenSSL libcrypto library.

METHODS

new

    require Net::DNS::SEC::Digest;
    $object = Net::DNS::SEC::Digest::SHA->new(256);

Creates and initialises a new digest object instance for the specified algorithm class.

add

    $object->add($data);
    $object->add($more);

Append specified data to the digest stream.

digest

    $digest = $object->digest;

Returns an octet string containing the calculated digest.

ACKNOWLEDGMENT

Thanks are due to Eric Young and the many developers and contributors to the OpenSSL cryptographic library.
