Constructor Detail

PBEKeyGenParams

public PBEKeyGenParams(Password pass,
                       byte[] salt,
                       int iterations)

Creates PBE parameters.

Parameters:

pass - The password. It will be cloned, so the caller is still responsible for clearing it. It must not be null.

salt - The salt for the PBE algorithm. Will not be cloned. Must not be null. It is the responsibility of the caller to use the right salt length for the algorithm. Most algorithms use 8 bytes of salt.

iterations - The iteration count for the PBE algorithm.

Creates PBE parameters using default encryption algorithm (DES3_EDE3_CBC).

Parameters:

encAlg - The encryption algorithm. This is used with SOME PBE algorithms for determining the KDF output length.

Method Detail

getPassword

public Password getPassword()

Returns a reference to the password, not a copy.

getSalt

public byte[] getSalt()

Returns a reference to the salt.

getIterations

public int getIterations()

Returns the iteration count.

getEncryptionAlgorithm

public EncryptionAlgorithm getEncryptionAlgorithm()

The encryption algorithm is used with SOME PBE algorithms for determining the KDF output length.

clear

public void clear()

Clears the password. This should be called when this object is no longer needed so the password is not left around in memory.

finalize

@Deprecated
protected void finalize()
                             throws java.lang.Throwable

Deprecated. finalize() in Object has been deprecated

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable
