Fields

public static final OAEPParameterSpec DEFAULT

Since: API Level 1

The algorithm parameter instance with default values.

It uses the following parameters:

  • message digest : "SHA-1"
  • mask generation function (mgf) : "MGF1"
  • parameters for the mgf : "SHA-1" SHA1
  • the source of the label L: DEFAULT

Public Constructors

public OAEPParameterSpec (String mdName, String mgfName, AlgorithmParameterSpec mgfSpec, PSource pSrc)

Since: API Level 1

mgfName the mask generation function algorithm name.
mgfSpec the algorithm parameter specification for the mask generation function algorithm.
pSrc the source of the label L.
Throws
NullPointerException if one of mdName, mgfName or pSrc is null.
