Constructs a secure random number generator (RNG) implementing the default random number algorithm.

Usage

From source file:grails.plugin.springsecurity.authentication.encoding.PBKDF2PasswordEncoder.java

public String encodePassword(String rawPass, Object saltIgnored) {
    char[] password = rawPass.toCharArray();

    // Generate a random salt
    byte[] salt = new byte[SALT_BYTE_SIZE];
    new SecureRandom().nextBytes(salt);

    // Hash the password
    byte[] hash = pbkdf2(password, salt, PBKDF2_ITERATIONS, HASH_BYTE_SIZE);

    // format iterations:salt:hash
    return PBKDF2_ITERATIONS + ":" + toHex(salt) + ":" + toHex(hash);
}
