OAEPParameterSpec

open class OAEPParameterSpec : AlgorithmParameterSpec

kotlin.Any
↳	javax.crypto.spec.OAEPParameterSpec

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

OAEPParameterSpec

Added in API level 1

OAEPParameterSpec(
    mdName: String!, 
    mgfName: String!, 
    mgfSpec: AlgorithmParameterSpec!, 
    pSrc: 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.

Parameters
mdName	String!: the algorithm name for the message digest.
mgfName	String!: the algorithm name for the mask generation function.
mgfSpec	AlgorithmParameterSpec!: the parameters for the mask generation function. If null is specified, null will be returned by getMGFParameters().
pSrc	PSource!: the source of the encoding input P.

Exceptions
java.lang.NullPointerException	if mdName, mgfName, or pSrc is null.
