                       int iterationCount)
                throws AlgorithmIdentifierException

Initializes this PBE instance with the specified PBE parameters.

Specified by:

initialize in class PBE

Parameters:

mode - The mode to use with this PBE. The mode is a PKCS5PBE mode value.

salt - The salt to use during the key generation.

iterationCount - The iteration count to use during the key generation.

Throws:

AlgorithmIdentifierException

initialize

public void initialize(int mode)
                throws AlgorithmIdentifierException

Initializes this PBE instance with the specified PBE parameters.

Specified by:

initialize in class PBE
