But how and where would I have the user input a social security number? public class ... The following Java example program generates a cryptographically secure random alphanumeric string. If cryptographic security is not a requirement, the SecureRandom class can be replaced with Random class for a much faster implementation. The following function can be used to generate random strings with a specified length. It is also possible to specify a subset of character set in the random string by modifying the CHARACTER_SET variable.
