rsa-encrypt-decrypt-rust

a small library to encrypt/decrypt data with RSA public/private key pair and base64/85 encoding/decoding capabilities.

you can generate your own key pair as:

Generating test public/private RSA key-pair.

openssl genrsa -out private.pem 2048
openssl rsa -in private.pem -out public.pem -pubout -outform PEM

Usage example

const TEST_PRIVATE_KEY: &str = "-----BEGIN RSA PRIVATE KEY-----
