Method Detail

getHash

byte[] getHash()

Get the hash segment of this password.

Returns:

the hash segment

getSalt

byte[] getSalt()

Get the salt segment of this password.

Returns:

the salt segment

getIterationCount

int getIterationCount()

Get the iteration count of this password.

Returns:

the iteration count

clone

BCryptPassword 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.

getParameterSpec

default IteratedSaltedPasswordAlgorithmSpec 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

createRaw

static BCryptPassword createRaw(String algorithm,
                                byte[] hash,
                                byte[] salt,
                                int iterationCount)

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

hash - the hash

salt - the salt

iterationCount - the iteration count

Returns:

the raw password implementation
