The random number services are designed to enable an application to access the random number source for its own purposes -for exmaple, generate One Time Password(OTP) for login verification. nCipher’s hardware architecture provides a true hardware random number generator. This is used at module initialisation to create a truly random and externally unpredictable.JCE inteface is commonly provided by HSM vendors, here is a example to call JCE sample
//Initialize the secure random generator SecureRandom sec_rand= SecureRandom.getInstance(randomSPI,JCEProvider); //generate a random bytes byte bytes[] = new byte[byteslen]; sec_rand.nextBytes(bytes); return bytes;
