class MbedTLS::Digest::MD2

Overview

A binding to the mbed TLS implementation of the MD2 digest algorithm.

NOTE The MD2 digest algorithm is old and most vendors do not  build mbed TLS with support for it.

DEPRECATED The MD2 digest algorithm is no longer considered cryptographically secure. Restrict its use to backwards compatibile applications, and plan to halt its use entirely in the future.

Constructor Detail

def self.new #

Creates a new instance for hashing data with MD2. Raises a DigestError if the linked copy of libmbedcrypto was not compiled with support for the MD2 digest algorithm.


Class Method Detail

def self.is_supported? #

Whether the linked libmbedcrypto supports the MD2 digest.


Instance Method Detail

def clone : MD2 #

Creates a new MD2 instance with the same internal state. Raises a DigestError if a library issue happens during the clone operation.


def digest_size : UInt8 #

The size of the digest's output, in bytes. This is the size of the raw digest, not it's hex representation.


def md_type_of : Type #

The Type enum of this Digest algorithm.
