MGF1ParameterSpec

public class MGF1ParameterSpec
extends Object implements AlgorithmParameterSpec

java.lang.Object
↳	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 --
 }

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
