    • Method Detail

      • bcryptHash

        public static String bcryptHash​(String password)
        Produces a Modular Crypt Format bcrypt hash of the given password, using a generated salt and 10 iterations.
        Parameters:
        password - the password to hash
        Returns:
        the Modular Crypt Format bcrypt hash of the given password
        Throws:
        NullPointerException - if the password is null

        public static String bcryptHash​(String password,
                                        int iterationCount)
        Produces a Modular Crypt Format bcrypt hash of the given password, using a generated salt and the specified iteration count.
        Parameters:
        password - the password to hash
        iterationCount - the number of iterations to use while hashing
        Returns:
        the Modular Crypt Format bcrypt hash of the given password
        Throws:
        NullPointerException - if the password is null
        IllegalArgumentException - if the iterationCount parameter is negative or zero

        public static String bcryptHash​(String password,
                                        int iterationCount,
                                        byte[] salt)
        Produces a Modular Crypt Format bcrypt hash of the given password, using the specified salt and the specified iteration count.
        Parameters:
        password - the password to hash
        iterationCount - the number of iterations to use while hashing
        salt - the salt to use while hashing
        Returns:
        the Modular Crypt Format bcrypt hash of the given password
        Throws:
        NullPointerException - if the password or salt are null
        IllegalArgumentException - if the iterationCount parameter is negative or zero, or if the salt length is not equal to 16
