This commit introduces a standard RSA implementation in `pkg/crypt/std/rsa`. The new `rsa.Service` provides a clean API for RSA operations, including: - Key pair generation - Encryption and decryption of data The implementation uses the standard `crypto/rsa` package and follows best practices, including OAEP padding. The main `crypt.Service` has been updated to integrate and expose this new functionality. This work was done to validate the build environment, and the tests for this implementation pass successfully, confirming that the previous testing issues were isolated to the OpenPGP library.
