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.

getEncryptor

protected Encryptor getEncryptor(String encryptorKey)

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

switchEncryptor

public void switchEncryptor(String encryptorKey)

Description copied from interface: SwitchableEncryptor

Switches the Encryptor to the one specified by encryptorKey or disable encryption when encryptorKey is null.

Specified by:

switchEncryptor in interface SwitchableEncryptor

Parameters:

encryptorKey - identifies one of the Encryptor or no encryption when null.

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

getAvailableEncryptorKeys

public Collection<String> getAvailableEncryptorKeys()

Specified by:

getAvailableEncryptorKeys in interface SwitchableEncryptor

Returns:

available encryptors' keys

getCurrentEncryptorKey

public Optional<String> getCurrentEncryptorKey()

Specified by:

getCurrentEncryptorKey in interface SwitchableEncryptor

Returns:

key of the currently used Encryptor or Optional.empty() when encryption is disabled
