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.
