Detailed Description
Helper class for password hash types that have a delimited set of parameters inside of the hash.
All passwords are in the form of :<TYPE>:... as explained in the main Password class. This class is for hashes in the form of :<TYPE>:<PARAM1>:<PARAM2>:... where <PARAM1>, <PARAM2>, etc. are parameters that determine how the password was hashed. Of course, the internal delimiter (which is : by convention and default), can be changed by overriding the ParameterizedPassword::getDelimiter() function.
This class requires overriding an additional function: ParameterizedPassword::getDefaultParams(). See the function description for more details on the implementation.

Member Function Documentation
◆ getDefaultParams()
|
abstractprotected |
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 in LayeredParameterizedPassword, EncryptedPassword, BcryptPassword, Pbkdf2Password, MWSaltedPassword, and MWOldPassword.
Referenced by needsUpdate(), and parseHash().
◆ getDelimiter()
|
abstractprotected |
Returns the delimiter for the parameters inside the hash.
- Returns
- string
Reimplemented in Pbkdf2Password, BcryptPassword, MWSaltedPassword, LayeredParameterizedPassword, MWOldPassword, and EncryptedPassword.
Referenced by parseHash(), LayeredParameterizedPassword\partialCrypt(), and toString().
◆ needsUpdate()
| ParameterizedPassword::needsUpdate | ( | ) |
Determine if the hash needs to be updated.
- Returns
- bool True if needs update, false otherwise
Reimplemented from Password.
Definition at line 81 of file ParameterizedPassword.php.
References getDefaultParams().
◆ parseHash()
|
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 $hash The hash, with the :<TYPE>: prefix stripped
- Exceptions
-
PasswordError If there is an error in parsing the hash
Reimplemented from Password.
Reimplemented in BcryptPassword.
Definition at line 52 of file ParameterizedPassword.php.
References Password\$hash, captcha-old\args, captcha-old\count, getDefaultParams(), and getDelimiter().
◆ toString()
| ParameterizedPassword::toString | ( | ) |
Convert this hash to a string that can be stored in the database.
The resulting string should be considered the seralized representation of this hash, i.e., if the return value were recycled back into PasswordFactory::newFromCiphertext, the returned object would be equivalent to this; also, if two objects return the same value from this function, they are considered equivalent.
- Returns
- string
- Exceptions
-
PasswordError if password cannot be serialized to fit a tinyblob.
