Generate an RSA keypair with an exponent of 65537 in PEM format

param: bits The key length in bits

Return private key and public key

new_key=RSA.generate(bits, e=65537)

public_key=new_key.publickey().exportKey('PEM')

private_key=new_key.exportKey('PEM')

Generating Keys for Encryption and Decryption.; 3 minutes to read +7; In this article. Creating and managing keys is an important part of the cryptographic process. Symmetric algorithms require the creation of a key and an initialization vector (IV). The key must be kept secret from anyone who should not decrypt your data. Remove RSA crypto operations from BCCSP. // Ephemeral returns true if the key to generate has to be ephemeral. ('Certificate's public key type not recognized. Oct 02, 2015 SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys.

Pycrypto is unmaintained and has known vulnerabilities. Use pycryptodome, it is a drop-in replacement.

e should be random methinks =P

@miigotu 'youthinks' wrong. e should be chosen so that e and λ(n) are coprime. It is not chosen at random, and since it is usually small for computation reasons, and included in the public key, it can always be known by an attacker anyway.

from Crypto.PublicKey import RSA
code = 'nooneknows'

key = RSA.generate(2048)
privatekey = key.exportKey(passphrase=code, pkcs=8)
publickey = key.publickey().exportKey()

Nice But How Can I Write The Private Key I Tried This:
f = open('PublicKey.pem','w')
f.write(publick_key)
f.close()

BUT IT DOESN'T WORK WITH THE PRIVATE KEY, JUST RETURNS 0B
