DrbgParameters.Instantiation

public static final class DrbgParameters.Instantiation
extends Object implements SecureRandomParameters

java.lang.Object
↳	java.security.DrbgParameters.Instantiation

DRBG parameters for instantiation.

When used in SecureRandom.getInstance(String, SecureRandomParameters) or one of the other similar getInstance calls that take a SecureRandomParameters parameter, it means the requested instantiate parameters the newly created SecureRandom object must minimally support. When used as the return value of the SecureRandom.getParameters() method, it means the effective instantiate parameters of the SecureRandom object.

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.

Public methods

getCapability

Added in API level 35

public DrbgParameters.Capability getCapability ()

Returns the capability.

Returns
`DrbgParameters.Capability`	If used in `getInstance`, returns the minimum capability requested. If used in `getParameters`, returns information on the effective prediction resistance flag and whether it supports reseeding.

getPersonalizationString

Added in API level 35

public byte[] getPersonalizationString ()

Returns the personalization string as a byte array.

Returns
`byte[]`	If used in `getInstance`, returns the requested personalization string as a newly allocated array, or `null` if no personalization string is requested. The same string should be returned in `getParameters` as a new copy, or `null` if no personalization string is requested in `getInstance`.

getStrength

Added in API level 35

public int getStrength ()

Returns the security strength in bits.

Returns
`int`	If used in `getInstance`, returns the minimum strength requested, or -1 if there is no specific request on the strength. If used in `getParameters`, returns the effective strength. The effective strength must be greater than or equal to the minimum strength requested.

toString

Added in API level 35

public String toString ()

Returns a Human-readable string representation of this Instantiation.

Returns
`String`	the string representation
