NAME

Venus::Role::Digestable - Digestable Role

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];
  }

  package main;

  my $example = Example->new(data => 123);

  # $example->digest;

  # "a6c3d9ae59f31690eddbdd15271e856a6b6f15d5"

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(string $algo, string $method, any @args) (string)

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.

Since 0.01

b64digest example 1

  package main;

  my $example = Example->new(data => 123);

  my $b64digest = $example->b64digest;

  # "/PFIeIRxSIuCLPcrbWypwXVUpMY"

b64digest example 2

  package main;

  my $example = Example->new(data => 123);

  my $b64digest = $example->b64digest('sha-1', 'execute');

  # "T+raai5I0suKC3VpiZ8bqt0WXE0"

b64digest example 3

  package main;

  my $example = Example->new(data => 123);

  my $b64digest = $example->b64digest('sha-1', 'execute', '456');

  # "5Vf077AO11mZZfaQknfOtzfhzPc"

bindigest

  bindigest(string $algo, string $method, any @args) (string)

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.

Since 0.01

bindigest example 1

  package main;

  my $example = Example->new(data => 123);

  my $bindigest = $example->bindigest;

  # pack("H*","fcf148788471488b822cf72b6d6ca9c17554a4c6")

bindigest example 2

  package main;

  my $example = Example->new(data => 123);

  my $bindigest = $example->bindigest('sha-1', 'execute');

  # pack("H*","4feada6a2e48d2cb8a0b7569899f1baadd165c4d")

bindigest example 3

  package main;

  my $example = Example->new(data => 123);

  my $bindigest = $example->bindigest('sha-1', 'execute', '456');

  # pack("H*","e557f4efb00ed7599965f6909277ceb737e1ccf7")

digest

  digest(string $algo, string $method, any @args) (string)

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.

Since 0.01

digest example 1

  package main;

  my $example = Example->new(data => 123);

  my $digest = $example->digest;

  # "fcf148788471488b822cf72b6d6ca9c17554a4c6"

digest example 2

  package main;

  my $example = Example->new(data => 123);

  my $digest = $example->digest('sha-1', 'execute');

  # "4feada6a2e48d2cb8a0b7569899f1baadd165c4d"

digest example 3

  package main;

  my $example = Example->new(data => 123);

  my $digest = $example->digest('sha-1', 'execute', '456');

  # "e557f4efb00ed7599965f6909277ceb737e1ccf7"

digester

  digester(string $algo, string $method, any @args) (string)

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.

Since 0.01

digester example 1

  package main;

  my $example = Example->new(data => 123);

  my $digester = $example->digester;

  # bless(..., "Digest::SHA")

digester example 2

  package main;

  my $example = Example->new(data => 123);

  my $digester = $example->digester('md5');

  # bless(..., "Digest::MD5")

hexdigest

  hexdigest(string $algo, string $method, any @args) (string)

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.

Since 0.01

hexdigest example 1

  package main;

  my $example = Example->new(data => 123);

  my $hexdigest = $example->hexdigest;

  # "fcf148788471488b822cf72b6d6ca9c17554a4c6"

hexdigest example 2

  package main;

  my $example = Example->new(data => 123);

  my $hexdigest = $example->hexdigest('sha-1', 'execute');

  # "4feada6a2e48d2cb8a0b7569899f1baadd165c4d"

hexdigest example 3

  package main;

  my $example = Example->new(data => 123);

  my $hexdigest = $example->hexdigest('sha-1', 'execute', '456');
