A different and better way to find prime numbers

[Sterling Christensen]

Ecryption

Encryption? A good idea, but how would you differentiate between prime numbers, such as 23 VS 233? Would numbers with less than 4 digits be converted to 4-digit numbers using zeroes for padding or something (I do that for octal and hexadecimal usually)?

I dunno how it works... I just know most modern encryption techniques use prime numbers.
