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.

getCapability

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

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

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

public String toString ()

Returns a Human-readable string representation of this Instantiation.

Returns
String the string representation
