Passphrases using netscape mail server's method

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 \s-1MD5\s0 digest algorithm. The passphrase and a salt are concatenated, along with some fixed bytes, and this record is hashed through \s-1MD5\s0. The output of \s-1MD5\s0 is the password hash.
This algorithm is deprecated, and is supported for compatibility only. Prefer the mechanism of Authen::Passphrase::SaltedDigest.
Generates a new passphrase recogniser object using the Netscape Mail Server algorithm. The following attributes may be given:
The salt, as a raw 32-byte string. It may be any 32-byte string, but it is conventionally limited to lowercase hexadecimal digits.
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.
The hash, as a string of 16 bytes.
The hash, as a string of 32 hexadecimal digits.
A passphrase that will be accepted.
The salt must be given, and either the hash or the passphrase.
Generates a new Netscape Mail Server passphrase recogniser object from an \s-1RFC\s0 2307 string. The string must consist of "{\s-1NS-MTA-MD5\s0}" (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 \s-1RFC\s0 2307 string.
Returns the salt value, as a string of 32 bytes. Returns the hash value, as a string of 16 bytes. Returns the hash value, as a string of 32 hexadecimal digits. These methods are part of the standard Authen::Passphrase interface.
