class Digest::MD5

Overview

Implements the MD5 digest algorithm.

Warning: MD5 is no longer a cryptographically secure hash, and should not be used in security-related components, like password hashing. For passwords, see Crypto::Bcrypt::Password. For a generic cryptographic hash, use SHA-256 via OpenSSL::Digest.new("SHA256").

Defined in:

digest/md5.cr
