All Implemented Interfaces:

AlgorithmParameterSpec, java.security.spec.AlgorithmParameterSpec

public class RSAOAEPParameterSpec

extends java.lang.Object

implements AlgorithmParameterSpec

This class specifies parameters for RSA-OAEP (implemented by RSA_PKCS1_v2_1). The parameters consist of the OIDs of a hash function, mask generation function, and PSource algorithm.

The default hash function is SHA1 (1.3.14.3.2.26). The only supported mask generation function is MGF1 (1.2.840.113549.1.1.8). The only supported PSource algorithm is pSpecified (1.2.840.113549.1.1.9).
