Class LunaParameterSpecOAEP

java.lang.Object

com.safenetinc.luna.provider.param.LunaParameterSpecOAEP

All Implemented Interfaces:

java.security.spec.AlgorithmParameterSpec

public class LunaParameterSpecOAEP
extends java.lang.Object
implements java.security.spec.AlgorithmParameterSpec

A parameter spec for OAEP parameters There is actually very little flexibility in the OAEP parameter specification. The hash algorithm must be SHA1, the mask generation function must be MGF1 and the source type must be DATA_SPECIFIED. Nonetheless, all of these fields must be specified with the generic constructor.

Constructor Detail

LunaParameterSpecOAEP

public LunaParameterSpecOAEP()

Default constructor for a LunaParameterSpecOAEP object. The hash algorithm, mask function and data source are set to SHA1, MGF1 and DATA_SPECIFIED respectively. The source data is empty.

LunaParameterSpecOAEP

public LunaParameterSpecOAEP(java.lang.String hashAlg,
                     int mgfType)

LunaParameterSpecOAEP

public LunaParameterSpecOAEP(java.lang.String hashAlg,
                     int mgfType,
                     int sourceType,
                     byte[] sourceData)

Generic constructor for a LunaParameterOAEP object.

Parameters:

hashAlg - The hash algorithm to use ("SHA1", "SHA224", "SHA256", "SHA384", or "SHA512")

mgfType - The mask generation function to use (must be mgfType_MGF1)

sourceType - The source type to use (must be sourceType_DATA_SPECIFIED)

sourceData - The source data
