For details about how to read and decrypt public and private keys in python

Read the public/private key in python for encryption and decryption.

In RSA, one application mode is public key encryption and Private Key decryption (the other is Private Key signature and public key verification ). The following is an example of an application in Python.

Suppose I have a public key file, rsa_pub.pem. I want to read this public key and use it to encrypt it.

From M2Crypto import RSA, BIO fp = file ('rsa _ pub. pem', 'rb'); pub_key_str = fp. read (); fp. close (); mb = BIO. memoryBuffer (pub_key_str); pub_key = RSA. load_pub_key_bio (mb); data = '000000'; en_data = pub_key.public_encrypt (data, RSA. pkcs1_padding );...

Private Key File rsa_private.pem, which reads the private key and is used for decryption

From M2Crypto import RSA, BIO private_key_str = file ('rsa _ private. pem', 'rb '). read (); private_key = RSA. load_key_string (private_key_str); data = 'sdfdjslfjaskldfjdskljsd'; de_data = private_key.private_decrypt (data, RSA. pkcs1_padding );
