RSA PKCS#1 public key encryption using an ASN.1 DER encoded public key.
Implemented in pure Rust based on RFC8017: PKCS #1: RSA Cryptography Specifications Version 2.2, section 7.2.1 RSAES-PKCS1-v1_5.
Warning: Use at your own risk. Not extensively tested or reviewed. May contain serious bugs.
See also: rust-openssl. Example code written for rust-openssl:
rust
let mut shared_e = vec![0; rsa.size() as usize];
let mut token_e = vec![0; rsa.size() as usize];
rsa.public_encrypt(&shared, &mut shared_e, Padding::PKCS1)?;
rsa.public_encrypt(&packet.verify_token.data, &mut token_e, Padding::PKCS1)?;
could be rewritten using this crate as follows:
rust
let shared_e = rsa_public_encrypt_pkcs1::encrypt(&packet.public_key.data, &shared)?;
let token_e = rsa_public_encrypt_pkcs1::encrypt(&packet.public_key.data, &packet.verify_token.data)?;
