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.

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.

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.

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

{ since => '0.01', }

=example-1 digester

package main;

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

my $digester = $example->digester;

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

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.

b64digest(string $algo, string $method, any @args) (string)

{ since => '0.01', }

=example-1 b64digest

package main;

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

my $b64digest = $example->b64digest;

# "/PFIeIRxSIuCLPcrbWypwXVUpMY"

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.

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

{ since => '0.01', }

=example-1 bindigest

package main;

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

my $bindigest = $example->bindigest;

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

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.

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

{ since => '0.01', }

=example-1 hexdigest

package main;

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

my $hexdigest = $example->hexdigest;
