RUSTSEC-2024-0333: 
Rust vulnerability analysis and mitigation

This crate has been deprecated in favour of using the native support for exporting RSA keys into the standard PEM format.
See [docs.rs documentation]. In addition to that, the operations in this crate (arithmetic and Base64 encoding) are not done in constant-time, potentially [exposing the user to sidechannel attacks].
