- Enclosing class:
- DrbgParameters
public static final class DrbgParameters.Instantiation extends Object implements SecureRandomParameters
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.

Method Detail
getStrength
public int getStrength()
Returns the security strength in bits.
- Returns:
- If used in
getInstance
, returns the minimum strength requested, or -1 if there is no specific request on the strength. If used ingetParameters
, returns the effective strength. The effective strength must be greater than or equal to the minimum strength requested.
getCapability
public DrbgParameters.Capability getCapability()
Returns the capability.
- Returns:
- If used in
getInstance
, returns the minimum capability requested. If used ingetParameters
, 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:
- If used in
getInstance
, returns the requested personalization string as a newly allocated array, ornull
if no personalization string is requested. The same string should be returned ingetParameters
as a new copy, ornull
if no personalization string is requested ingetInstance
.
toString
public String toString()
Returns a Human-readable string representation of this Instantiation
.
