command line password encode

[darmbrust]

Adding something like this would be handy for preparing accounts for use cases like mine that involve docker, and pre-created accounts for system access.

PasswordHashPbkdf2

	public static void main(String[] args)
	{
		System.out.println("Please enter the password to hash:");
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String temp = br.readLine();
		System.out.println(new PasswordHashPbkdf2().toHashedEntry(temp.toCharArray(), ""));
	}
