# Random Small Primes

#### 10 to 100 digits (page 1 of 3)

A frequently asked question at the Prime Pages is the following.

I am working on a project for which I need some primes that are, say, 10 - 100 digits long, so the table that you have posted one the web is an overkill for me. Could you, please, tell me where I might go for those?

Below I give some small primes. Obviously these should not be used for cryptological uses which rely on the secrecy of the prime factors of a modulus (as they have been published here) but they will suffice for testing algorithms... I started with a string of "random" digits (created using UBASIC's irnd() function), checked for small prime divisors, and if there were none, I used APRT-CL for the primality proof.

Digits: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, (larger).
