Python generates a pair of RSA keys and saves the public and private keys as .pem files respectively. Use the public key in the generated RSA key pair to encrypt the data, and then use the private key to decrypt. Convert RSA’s public key exponent (E) and modulus (N) to .pem format

You can use the cryptography library to generate a pair of RSA keys and save the public and private keys as .pem files respectively. Here is a sample code: from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import serialization from cryptography.hazmat.primitives.asymmetric import rsa # Generate RSA key pair private_key = rsa.generate_private_key( public_exponent=65537, key_size=2048, backend=default_backend() ) # Get […]
