public boolean isSingleton()- Specified by:

-
setAlgorithm
Allows the Pseudo Random Number Generator (PRNG) algorithm to be nominated. Defaults to "SHA1PRNG".- Parameters:
algorithm
- to use (mandatory)
-
setSeed
public void setSeed(org.springframework.core.io.Resource seed) Allows the user to specify a resource which will act as a seed for theSecureRandom
instance. Specifically, the resource will be read into anInputStream
and those bytes presented to theSecureRandom.setSeed(byte[])
method. Note that this will simply supplement, rather than replace, the existing seed. As such, it is always safe to set a seed using this method (it never reduces randomness).- Parameters:
seed
- to use, ornull
if no additional seeding is needed
