Interface SecureRandomService

All Known Implementing Classes:
DefaultSecureRandomService
public interface SecureRandomService
A generator for random data which is cryptographically secure, based on the same interface as SecureRandom.

Using this interface instead of using SecureRandom directly will allow implementations to provide security or performance improvements (such as dynamic re-seeding) without any changes to client code.

Implementations are required to be thread-safe.
