Constructor Detail

PBEParameterSpec

public PBEParameterSpec(byte[] salt,
                        int iterationCount)

Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.

Parameters:

salt - the salt. The contents of salt are copied to protect against subsequent modification.

iterationCount - the iteration count.

Throws:

NullPointerException - if salt is null.

PBEParameterSpec

public PBEParameterSpec(byte[] salt,
                        int iterationCount,
                        AlgorithmParameterSpec paramSpec)

Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.

Parameters:

salt - the salt. The contents of salt are copied to protect against subsequent modification.

iterationCount - the iteration count.

paramSpec - the cipher algorithm parameter specification, which may be null.

Throws:

NullPointerException - if salt is null.
