Detailed Description

A PBKDF2-hashed password.

This is a computationally complex password hash for use in modern applications. The number of rounds can be configured by $wgPasswordConfig['pbkdf2']['cost'].

Member Function Documentation

◆ crypt()

Pbkdf2Password::crypt ( string $password )

Hash a password and store the result in this object.

The result of the password hash should be put into the internal state of the hash object.

Parameters

string $password Password to hash

Exceptions

PasswordError If an internal error occurs in hashing

Reimplemented from Password.

Definition at line 46 of file Pbkdf2Password.php.

◆ getDefaultParams()

Pbkdf2Password::getDefaultParams ( )

protected

Return an ordered array of default parameters for this password hash.

The keys should be the parameter names and the values should be the default values. Additionally, the order of the array should be the order in which they appear in the hash.

When parsing a password hash, the constructor will split the hash based on the delimiter, and consume as many parts as it can, matching each to a parameter in this list. Once all the parameters have been filled, all remaining parts will be considered extra arguments, except, of course, for the very last part, which is the hash itself.
