We can encrypt the data using the _RSAobj.encrypt() method, and then decrypt the encrypted message using the _crypt() method.īoth _RSAobj.encrypt() and _crypt() methods take a byte string or long as the input and perform the plain RSA encryption and decryption on the input, respectively. In plain RSA encryption, we can generate a key pair and encrypt the data using the public key.

There are two ways to perform asymmetric encryption using the RSA module in Python: plain RSA encryption and a more proper and secure way by cryptographic padding. RSA Encryption in Python Using Plain Encryption We can use asymmetric cryptography in Python using the RSA module in the following ways.

The advantage of asymmetric or public-key cryptography is that it also provides a method to ensure that the message is not tampered with and is authentic. The asymmetric cryptography method uses a pair of keys (public and private keys) for a secure conversation between two people.
