public interface PasswordHash
PasswordHash
is an interface for objects that can generate and verify password hashes.
Implementations of PasswordHash
are configured for the built-in Database IdentityStore
by configuring the type on the DatabaseIdentityStoreDefinition
annotation.
Parameters for the PasswordHash
can also be configured on the annotation,
and will be passed to the initialize(Map)
method when the IdentityStore
is initialized.
Modifier and Type | Method and Description |
---|---|
String |
generate(char[] password)
Generate an encoded password hash value for storage in a user's account.
|
default void |
initialize(Map<String,String> parameters)
Initialize the instance with the parameters it should use to
generate and verify password hashes.
|
boolean |
verify(char[] password,
String hashedPassword)
Verify a password against the hashed password value retrieved from a user's account.

default void initialize(Map<String,String> parameters)
DatabaseIdentityStoreDefinition.hashAlgorithmParameters()
attribute.
An implementation is not required to support parameters, and may ignore parameters passed to it. It is also possible that an implementation will use the specified parameters when generating a new password hash, but ignore them in favor of parameters stored with an existing password hash when verifying.
If no parameters were supplied, the argument is an empty Map
.
parameters
- A Map
of the provided parameters, empty if no parameters were supplied.String generate(char[] password)
This method should not be used to generate a password hash for verification purposes;
use verify(char[], String)
for that purpose. Use this method only to generate
password hashes for new or changed passwords.
The returned hash value should be fully encoded, such that it can be directly stored, as is, with no additional formatting or encoding applied.
password
- The password to generate a hash for.boolean verify(char[] password, String hashedPassword)
The hashedPassword
parameter should be provided exactly as retrieved from the database,
with no decoding or formatting applied. The password
parameter should be hashed and
compared to the hashed password.
password
- The password to verify.hashedPassword
- The hashed password to compare against.Copyright © 1996-2017, Oracle and/or its affiliates. All Rights Reserved. Use is subject to license terms.
