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 }
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
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
