Router(config)# crypto key generate rsa general-keys The name for the keys will be: myrouter.example.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.

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

How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
OR
ssh-keygen
Sample outputs:

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

  • $HOME/.ssh/id_rsa – Your private RSA key
  • $HOME/.ssh/id_rsa.pub – Your public RSA key

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id userName@server2.nixcraft.net.in
Finally, you can login to remote server as follows:
ssh userName@server2.nixcraft.net.in
scp file.txt userName@server2.nixcraft.net.in:~/data2/
