Constructor Details

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.
Since:
1.8

Method Details

getSalt

getIterationCount

public int getIterationCount()
Returns the iteration count.
Returns:
the iteration count

getParameterSpec

public AlgorithmParameterSpec getParameterSpec()
