Your password is too short...

This is a random password generator that I stuck in my CryptUtils file. It's reasonable for website logins, etc.

private static final String VOWELS = "aeiou";

private static final String CONSONANTS = "bcdfghjklmnpqrstvwxyz";



private static transient SecureRandom random;



static {

   try {

       random = SecureRandom.getInstance("SHA1PRNG");

   } catch(NoSuchAlgorithmException nsae) {

       //... static logging here.

   }

}



public static final String newPassword(int length) {



   if(random == null) {

           throw new RuntimeException("PRNG not initialised!");

   }



   if(length < 8) length = 8;



   length -= 3;



   char[] blabla = new char[length];



   for(int i = 0; i < blabla.length; i+= 2) {

       if(i >= blabla.length) break;

       blabla[i] = CONSONANTS.charAt(random.nextInt(CONSONANTS.length()));

   }



   for(int i = 1; i < blabla.length; i+= 2) {

       if(i >= blabla.length) break;

       blabla[i] = VOWELS.charAt(random.nextInt(VOWELS.length()));

   }



   String result = new String(blabla);



   if(result.indexOf("eni") != -1) {

           return newPassword(length+3);

   }



   return result + Integer.toString(random.nextInt(999));

}
