I have a file( simple.txt) and I generated public key and private key using openssl showed below
openssl genrsa -out key_pair.key 2048
private key :
openssl pkcs8 -topk8 -inform PEM -in key_pair.key -outform PEM -nocrypt -out
private_key.pem
publice key :
openssl rsa -in key_pair.key -pubout -outform PEM -out public_key.pem
now I want to encrypt and sign my file using this public and private key and send it to another person and then he can decrypt and check the signature that this file sent by me .mention that I don't want to generate public and private keys using RSA and I want to address my generated keys showed above .how can i use python to encrypt my file ?
