Published Jan 8, 2026

Modified 1 months ago

Details

The rsa crate is an RSA implementation written in rust. Prior to version 0.9.10, when creating a RSA private key from its components, the construction panics instead of returning an error when one of the primes is 1. Version 0.9.10 fixes the issue.
