This generates two random prime numbers of size 1024 and 2 respectively. Originally needed to perform diffie-hellman key exchange to generate private keys for https://justa.ml. Eventually I worked on other projects that required this - so I thought to make this a service for other apps to consume. Originally used a script to generate some large primes and saved them in a file. So this service does not generate them on the fly.
Is this number cryptographically secure? How do you get enough entropy in your server?
It's strange that the link points to the json file. I was expecting a webpage where I can see the numbers, some explanation and a link to the actual service.
