Detailed Description

A PBKDF2-hashed password, using PHP's hash extension.

This class exists for compatibility purposes only! Unless an installation's existing password hashes were generated using an algorithm not supported by OpenSSL, Pbkdf2PasswordUsingOpenSSL should be used.

Since

1.40 (since 1.29 under the old name)

Member Function Documentation

getDigestAlgo()

MediaWiki\Password\Pbkdf2PasswordUsingHashExtension::getDigestAlgo ( string $algo )

protected

Get the implementation specific name for a hash algorithm.

Parameters

string

$algo

Algorithm specified in the password hash string

Returns

string|null $algo Implementation specific name, or null if unsupported

Reimplemented from MediaWiki\Password\AbstractPbkdf2Password.

pbkdf2()

MediaWiki\Password\Pbkdf2PasswordUsingHashExtension::pbkdf2 ( string $digestAlgo, string $password, string $salt, int $rounds, int $length )

protected

Call the PBKDF2 implementation, which hashes the password.

Parameters

string	$digestAlgo	Implementation specific hash algorithm name
string	$password	Password to hash
string	$salt	Salt as a binary string
int	$rounds	Number of iterations
int	$length	Length of the hash value in bytes

Returns

string Hash value as a binary string

Exceptions

PasswordError

If an internal error occurs in hashing
