Class SaltingEncryptor

java.lang.Object

com.atlassian.crowd.crypto.SaltingEncryptor

All Implemented Interfaces:

Encryptor

public class SaltingEncryptor
extends Object
implements Encryptor

Encryptor that delegates another Encryptor and adds to them the salting feature.

The implementation works correctly with decrypting both salted and non-salted passwords, so after enabling no migration of the existing passwords will be needed. Nevertheless, new encrypted passwords will be salted.

Method Summary

Modifier and Type	Method and Description
boolean	changeEncryptionKey() Generate new encryption key, which should be used to encrypt password in following calls to Encryptor.encrypt(java.lang.String).
String	decrypt(String encryptedPassword) Decrypt encrypted password, and return its original value.
String	encrypt(String password) Encrypt plaintext password, and return encrypted value which can later be used in decrypt method to get plaintext password.

Method Detail

encrypt

public String encrypt(String password)

Description copied from interface: Encryptor

Encrypt plaintext password, and return encrypted value which can later be used in decrypt method to get plaintext password.

Specified by:

encrypt in interface Encryptor

Returns:

encrypted password.

decrypt

public String decrypt(String encryptedPassword)

Description copied from interface: Encryptor

Decrypt encrypted password, and return its original value.

In case of any error during decryption (such as missing decryption key) return encryptedPassword.

Specified by:

decrypt in interface Encryptor

Returns:

decrypted password or unchanged encryptedPassword in case of any error

changeEncryptionKey

public boolean changeEncryptionKey()

Description copied from interface: Encryptor

Generate new encryption key, which should be used to encrypt password in following calls to Encryptor.encrypt(java.lang.String).

Specified by:

changeEncryptionKey in interface Encryptor

Returns:

true if generation was successful, or false when encryption key migration is not supported
