Detailed Description

A Bcrypt-hashed password.

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

Member Function Documentation

◆ crypt()

BcryptPassword::crypt (   $password)
Parameters
string$passwordPassword to encrypt
Exceptions
PasswordErrorIf bcrypt has an unknown error
MWExceptionIf bcrypt is not supported by PHP

Reimplemented from Password.

Definition at line 54 of file BcryptPassword.php.

References Password\$hash, crypt(), MWCryptRand\generate(), and getDelimiter().

Referenced by crypt().

◆ getDefaultParams()

BcryptPassword::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.

Returns
array

Reimplemented from ParameterizedPassword.

Definition at line 32 of file BcryptPassword.php.

◆ getDelimiter()

BcryptPassword::getDelimiter ( )
protected

Returns the delimiter for the parameters inside the hash.

Returns
string

Reimplemented from ParameterizedPassword.

Definition at line 38 of file BcryptPassword.php.

◆ parseHash()

BcryptPassword::parseHash (   $hash)
protected

Perform any parsing necessary on the hash to see if the hash is valid and/or to perform logic for seeing if the hash needs updating.

Parameters
string$hashThe hash, with the :<TYPE>: prefix stripped
Exceptions
PasswordErrorIf there is an error in parsing the hash

Reimplemented from ParameterizedPassword.
