Authen::Passphrase::NTHash Description

Passphrases using the NT-Hash algorithm. Authen::Passphrase::NTHash is a Perl module with passphrases using the NT-Hash algorithm.SYNOPSIS use Authen::Passphrase::NTHash; $ppr = Authen::Passphrase::NTHash->new( hash_hex => "7f8fe03093cc84b267b109625f6bbf4b"); $ppr = Authen::Passphrase::NTHash->new( passphrase => "passphrase"); $ppr = Authen::Passphrase::NTHash->from_crypt( '$3$$7f8fe03093cc84b267b109625f6bbf4b'); $ppr = Authen::Passphrase::NTHash->from_rfc2307( '{MSNT}7f8fe03093cc84b267b109625f6bbf4b'); $hash = $ppr->hash; $hash_hex = $ppr->hash_hex; if($ppr->match($passphrase)) { ... $passwd = $ppr->as_crypt; $userPassword = $ppr->as_rfc2307;An object of this class encapsulates a passphrase hashed using the NT-Hash function. This is a subclass of Authen::Passphrase, and this document assumes that the reader is familiar with the documentation for that class.The NT-Hash scheme is based on the MD4 digest algorithm. Up to 128 characters of passphrase (characters beyond the 128th are ignored) are represented in Unicode, and hashed using MD4. No salt is used.Warning: MD4 is a weak hash algorithm by current standards, and the lack of salt is a design flaw in this scheme. Use this for compatibility only, not by choice. Requirements: · Perl
