Remarks

This class specifies the set of parameters used with OAEP Padding, as defined in the PKCS #1 standard.

Its ASN.1 definition in PKCS#1 standard is described below:

RSAES-OAEP-params ::= SEQUENCE {
              hashAlgorithm      [0] OAEP-PSSDigestAlgorithms     DEFAULT sha1,
              maskGenAlgorithm   [1] PKCS1MGFAlgorithms  DEFAULT mgf1SHA1,
              pSourceAlgorithm   [2] PKCS1PSourceAlgorithms  DEFAULT pSpecifiedEmpty
            }

where

OAEP-PSSDigestAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-sha1 PARAMETERS NULL   }|
              { OID id-sha256 PARAMETERS NULL }|
              { OID id-sha384 PARAMETERS NULL }|
              { OID id-sha512 PARAMETERS NULL },
              ...  -- Allows for future expansion --
            }
            PKCS1MGFAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-mgf1 PARAMETERS OAEP-PSSDigestAlgorithms },
              ...  -- Allows for future expansion --
            }
            PKCS1PSourceAlgorithms    ALGORITHM-IDENTIFIER ::= {
              { OID id-pSpecified PARAMETERS OCTET STRING },
              ...  -- Allows for future expansion --
            }

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

Constructors

OAEPParameterSpec(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

OAEPParameterSpec(String, String, IAlgorithmParameterSpec, PSource)

Constructs a parameter set for OAEP padding as defined in the PKCS #1 standard using the specified message digest algorithm mdName, mask generation function algorithm mgfName, parameters for the mask generation function mgfSpec, and source of the encoding input P pSrc.
