Pretty please don't use this for anything requiring real security. I am building it to gain an understanding of how RSA works and how attacks on it function, and as such it is almost certainly vulnerable to many of them
This library implements RSA and RSA-related functionality. Currently, you can generate 1024-bit prime numbers, check any bignum::BigUint for primality, encrypt, and decrypt messages with very naive 1024-bit RSA:
extern crate rsa;
fn main() {
let p = rsa::primes::big_prime(1024);
println!("'{} is prime' is a {} statement!", p, rsa::primes::is_prime(&p));
//-> '{Some 1024-bit prime number} is prime' is a true statement!
let message = ~"Some super secret scary message that I don't want anybody to see!";
let (public_key, private_key) = rsa::gen_keys_default();
let encrypted = public_key.encrypt(message);
println!("The secret message is hidden inside of '{}'", encrypted); //-> A bunch of hex
let decrypted = private_key.decrypt(encrypted);
println!("But we can get it out! It is '{}'", decrypted); //-> super secret scary message
}To build and test:
make deps && make testTo install into system rustlib:
make installTo build examples:
make examplesExamples can then be run from build/examples. (Note: building examples also installs the library system-wide, which may not be desired.)
