Method Details

getSalt

byte[] getSalt()

Get the salt component of this password.

Returns:

the salt component

getHash

byte[] getHash()

Get the hash component of this password.

Returns:

the hash component

getParameterSpec

default SaltedPasswordAlgorithmSpec getParameterSpec()

Description copied from interface: Password

Get the applicable algorithm parameter specification for this password type.

Specified by:

getParameterSpec in interface Password

Returns:

the algorithm parameter specification, or null if this password type does not support algorithms

impliesParameters

default boolean impliesParameters(AlgorithmParameterSpec parameterSpec)

Description copied from interface: Password

Determine if this password is matched by the given parameter specification.

Specified by:

impliesParameters in interface Password

Parameters:

parameterSpec - the parameter specification (must not be null)

Returns:

true if the password is matched by the parameters, false otherwise

clone

UnixMD5CryptPassword clone()

Creates and returns a copy of this Password.

Specified by:

clone in interface OneWayPassword

Specified by:

clone in interface Password

Returns:

a copy of this Password.

createRaw

static UnixMD5CryptPassword createRaw(String algorithm,
 byte[] salt,
 byte[] hash)

Create a raw implementation of this password type. No validation of the content is performed, and the password must be "adopted" in to a PasswordFactory (via the PasswordFactory.translate(Password) method) before it can be validated and used to verify guesses.

Parameters:

algorithm - the algorithm name

salt - the salt

hash - the hash

Returns:

the raw password implementation
