Code Snippet for Creating Secure Token in Java

Tokens can be used for many things.  Among them are Single Sign On, or saving an identification number without exposing it to the web.  Here is a quick code snippet to create a 16 character token

First you need an import:


here is the code snippet:

String token1 = null;
SecureRandom secureRandom = new SecureRandom();
String secString = new BigInteger(130, secureRandom).toString(32);
token1 = secString.substring(0, 15);  //creates a 16 character token

Alter the substring end value to change the size of the token.

Hope this helps someone.
