* This class specifies the set of parameters used with OAEP Padding,

* hashAlgorithm [0] OAEP-PSSDigestAlgorithms DEFAULT sha1,
* maskGenAlgorithm [1] PKCS1MGFAlgorithms DEFAULT mgf1SHA1,
* pSourceAlgorithm [2] PKCS1PSourceAlgorithms DEFAULT pSpecifiedEmpty

* { OID id-sha384 PARAMETERS NULL }|
* { OID id-sha512 PARAMETERS NULL },

* <p>Note: the OAEPParameterSpec.DEFAULT uses the following:
* message digest -- "SHA-1"
* mask generation function (mgf) -- "MGF1"
* parameters for mgf -- MGF1ParameterSpec.SHA1
* source of encoding input -- PSource.PSpecified.DEFAULT
