MGF1ParameterSpec

open class MGF1ParameterSpec : AlgorithmParameterSpec

kotlin.Any
↳	java.security.spec.MGF1ParameterSpec

This class specifies the set of parameters used with mask generation function MGF1 in OAEP Padding and RSASSA-PSS signature scheme, as defined in the PKCS#1 v2.2 standard.

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

PKCS1MGFAlgorithms    ALGORITHM-IDENTIFIER ::= {
    { OID id-mgf1 PARAMETERS HashAlgorithm },
    ...  -- Allows for future expansion --
  }

where

HashAlgorithm ::= AlgorithmIdentifier {
    {OAEP-PSSDigestAlgorithms}
  }
 
  OAEP-PSSDigestAlgorithms    ALGORITHM-IDENTIFIER ::= {
    { OID id-sha1       PARAMETERS NULL }|
    { OID id-sha224     PARAMETERS NULL }|
    { OID id-sha256     PARAMETERS NULL }|
    { OID id-sha384     PARAMETERS NULL }|
    { OID id-sha512     PARAMETERS NULL }|
    { OID id-sha512-224 PARAMETERS NULL }|
    { OID id-sha512-256 PARAMETERS NULL },
    ...  -- Allows for future expansion --
  }
