ABSTRACT
Digestable Role for Perl 5
SYNOPSIS
package Example;
use Venus::Class;
attr 'data';
with 'Venus::Role::Dumpable';
with 'Venus::Role::Digestable';
sub execute {
my ($self, @args) = @_;
return [$self->data, @args];
}

# $example->digest;

DESCRIPTION
This package modifies the consuming package and provides methods for producing message digests from a dump of the object or the return value of a dispatched method call. All algorithms supported by Digest are supported, e.g. SHA-1
, SHA-224
, SHA-256
, SHA-384
, SHA-512
, HMAC-MD5
, HMAC-SHA-1
, etc.
METHODS
This package provides the following methods:
b64digest
b64digest(Str $algo, Str $method, Any @args) (Str)
The b64digest method returns a base64 formatted digest of the object or return value of a dispatched method call. The algorithm defaults to SHA-1
. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

bindigest
bindigest(Str $algo, Str $method, Any @args) (Str)
The bindigest method returns a binary formatted digest of the object or return value of a dispatched method call. The algorithm defaults to SHA-1
. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

digest
digest(Str $algo, Str $method, Any @args) (Str)
The digest method returns a hexadecimal formatted digest of a dump of the object or return value of a dispatched method call. The algorithm defaults to SHA-1
. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

digester
digester(Str $algo, Str $method, Any @args) (Str)
The digester method returns a Digest object with a dump of the object or return value of a dispatched method call as the message. The algorithm defaults to SHA-1
. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.

hexdigest
hexdigest(Str $algo, Str $method, Any @args) (Str)
The hexdigest method returns a ... formatted digest of the object or return value of a dispatched method call. The algorithm defaults to SHA-1
. This method supports dispatching, i.e. providing a method name and arguments whose return value will be acted on by this method.
