NAME

       Authen::Passphrase::AcceptAll - accept any passphrase

SYNOPSIS

	       use Authen::Passphrase::AcceptAll;

	       $ppr = Authen::Passphrase::AcceptAll->new;

	       $ppr = Authen::Passphrase::AcceptAll
		       ->from_crypt("");

	       $ppr = Authen::Passphrase::AcceptAll
		       ->from_rfc2307("{CRYPT}");

	       if($ppr->match($passphrase)) { ...

	       $passphrase = $ppr->passphrase;

	       $passwd = $ppr->as_crypt;
	       $userPassword = $ppr->as_rfc2307;

DESCRIPTION

       An object of this class is a passphrase recogniser that accepts any passphrase whatsoever.  This is a subclass of Authen::Passphrase, and
       this document assumes that the reader is familiar with the documentation for that class.

       This type of passphrase recogniser is obviously of no use at all in controlling access to any resource.	Its use is to permit a resource to
       be public in a system that expects some type of passphrase access control.

CONSTRUCTORS

       Authen::Passphrase::AcceptAll->new
	   Returns an accept-all passphrase recogniser object.	The same object is returned from each call.

       Authen::Passphrase::AcceptAll->from_crypt("")
	   Returns an accept-all passphrase recogniser object.	The same object is returned from each call.  The argument must be the empty
	   string.

       Authen::Passphrase::AcceptAll->from_rfc2307(USERPASSWORD)
	   Generates a new accept-all passphrase recogniser object from an RFC 2307 string.  The string must consist of "{CRYPT}" (case
	   insensitive) followed by an acceptable crypt string.

METHODS

       $ppr->match(PASSPHRASE)
       $ppr->passphrase
       $ppr->as_crypt
       $ppr->as_rfc2307
	   These methods are part of the standard Authen::Passphrase interface.  The "match" method always returns true, and the "passphrase"
	   method returns the empty string (the shortest of the infinite number of correct passphrases).

NAME

       Authen::Passphrase::NetscapeMail - passphrases using Netscape Mail Server's method

SYNOPSIS

	       use Authen::Passphrase::NetscapeMail;

	       $ppr = Authen::Passphrase::NetscapeMail->new(
		       salt => "8fd9d0a03491ce8f99cfbc9ab39f0dd5",
		       hash_hex => "983757d7b519e86d9b5d472aca4eea3a");

	       $ppr = Authen::Passphrase::NetscapeMail->new(
		       salt_random => 1,
		       passphrase => "passphrase");

	       $ppr = Authen::Passphrase::NetscapeMail->from_rfc2307(
		       "{NS-MTA-MD5}8fd9d0a03491ce8f99cfbc9ab39f0dd5".
		       "983757d7b519e86d9b5d472aca4eea3a");

	       $salt = $ppr->salt;
	       $hash = $ppr->hash;
	       $hash_hex = $ppr->hash_hex;

	       if($ppr->match($passphrase)) { ...

	       $userPassword = $ppr->as_rfc2307;

DESCRIPTION

       An object of this class encapsulates a passphrase hashed using the algorithm used by Netscape Mail Server.  This is a subclass of
       Authen::Passphrase, and this document assumes that the reader is familiar with the documentation for that class.

       The Netscape Mail Server scheme is based on the MD5 digest algorithm.  The passphrase and a salt are concatenated, along with some fixed
       bytes, and this record is hashed through MD5.  The output of MD5 is the password hash.

       This algorithm is deprecated, and is supported for compatibility only.  Prefer the mechanism of Authen::Passphrase::SaltedDigest.

CONSTRUCTORS

       Authen::Passphrase::NetscapeMail->new(ATTR => VALUE, ...)
	   Generates a new passphrase recogniser object using the Netscape Mail Server algorithm.  The following attributes may be given:

	   salt
	       The salt, as a raw 32-byte string.  It may be any 32-byte string, but it is conventionally limited to lowercase hexadecimal digits.

	   salt_random
	       Causes salt to be generated randomly.  The value given for this attribute is ignored.  The salt will be a string of 32 lowercase
	       hexadecimal digits.  The source of randomness may be controlled by the facility described in Data::Entropy.

	   hash
	       The hash, as a string of 16 bytes.

	   hash_hex
	       The hash, as a string of 32 hexadecimal digits.

	   passphrase
	       A passphrase that will be accepted.

	   The salt must be given, and either the hash or the passphrase.

       Authen::Passphrase::NetscapeMail->from_rfc2307(USERPASSWORD)
	   Generates a new Netscape Mail Server passphrase recogniser object from an RFC 2307 string.  The string must consist of "{NS-MTA-MD5}"
	   (case insensitive) followed by the hash in case-insensitive hexadecimal and then the salt.  The salt must be exactly 32 characters
	   long, and cannot contain any character that cannot appear in an RFC 2307 string.

METHODS

       $ppr->salt
	   Returns the salt value, as a string of 32 bytes.

       $ppr->hash
	   Returns the hash value, as a string of 16 bytes.

       $ppr->hash_hex
	   Returns the hash value, as a string of 32 hexadecimal digits.

       $ppr->match(PASSPHRASE)
       $ppr->as_rfc2307
	   These methods are part of the standard Authen::Passphrase interface.
