Store a reference to a single SecureRandom in Java?

should help you out In Java anything that is not a primitive type (boolean, char, byte, short, int, long, float, double) is a reference type. The only way to copy a reference type is to do so explicitly through cloning, serialization, copy-constructing, etc. You're not using clone() or its ilk there, and you're not using a constructor. You're just doing assignment. This means you're copying the reference.

Difference between java.util.Random and java.security.SecureRandom

Does that help The standard Oracle JDK 7 implementation uses what's called a Linear Congruential Generator to produce random values in java.util.Random.
Taken from java.util.Random source code (JDK 7u2), from a comment on the method protected int next(int bits), which is the one that generates the random values:

Java SecureRandom as salt

like below fixes the issue First, it would be enough to use nextBytes (that actually calls the PRNG) instead of generateSeed. The latter uses the seed generation algorithm, which is a more complex operation since it needs an entropy source (800-90A p19-23)
code :
SecureRandom random = new SecureRandom();
byte[] salt = new byte[64];
random.nextBytes(salt);

String password="god";
MessageDigest md = MessageDigest.getInstance("SHA-512");
md.update(password.getBytes(Charset.forName("UTF-8")));
md.update(salt);

byte[] digest = md.digest();

What are use cases to use `SecureRandom.base64` over `SecureRandom.hex`?

it helps some times The difference between Base64 and hex is really just how bytes are represented. Hex is another way of saying "Base16". Hex will take two characters for each byte - Base64 takes 4 characters for every 3 bytes, so it's more efficient than hex. ... If it does matter, then clearly Base64 is better on that front.

I wish this help you Turns out it does work. For some reason eclipse just highlighted it as an error even though it works.

SecureRandom.hex() vs SecureRandom.random_bytes() for key generation in Rails with attr_encrypted

like below fixes the issue SecureRandom#hex is defined here as:
code :
def hex(n=nil)
  random_bytes(n).unpack("H*")[0]
end
