title: a beginner's guide to rsa encryption and decryption in python
rsa (rivest-shamir-adleman) is a widely used public-key cryptosystem that is capable of secure communication over an insecure channel. in this tutorial, we'll walk through the basics of rsa encryption and decryption in python using the cryptography library.
prerequisites:
installation:
first, you need to install the cryptography library if you haven't already. you can do this via pip:
rsa encryption and decryption example:
explanation:
key generation: we generate a key pair consisting of a private key and a corresponding public key using the generate_key_pair() function.
saving keys: optionally, you can save the generated keys to files for later use.
encryption: we encrypt a message using the public key with the encrypt_message() function. rsa encryption is done using padding to ensure security.
decryption: we decrypt the encrypted message using the private key with the decrypt_message() function.
output: finally, we print the encrypted and decrypted messages to demonstrate the encryption and decryption process.
this example showcases the basics of rsa encryption and decryption using the cryptography library in python. feel free to explore further and integrate these concepts into your own projects for secure communication.
