The other part is kept secret, and is called the private key. The two parts are related, in that if you encrypt a message with one of the parts, you can decrypt it with the other part, and only with the other part. Starting from Python 2.7.9, the ssl module disables certain weak ciphers by default, but you may. Another security recommendation is to set a passphrase. The passphrase is similar to a password, which will be asked to use your private key. Depending on your configuration, that could be each time you want to connect via ssh (the most secure way to use it). Here are basic commands to generate the keys. Generates a new RSA private key using the provided backend. Keysize describes how many bits long the key should be. Larger keys provide more security; currently 1024 and below are considered breakable while 2048 or 4096 are reasonable default key sizes for new keys.

Python Generate Secure Private Key Code
How To Secure Python Code
The following steps are involved in generating RSA keys −
Create two large prime numbers namely p and q. The product of these numbers will be called n, where n= p*q
Generate a random number which is relatively prime with (p-1) and (q-1). Let the number be called as e.
Calculate the modular inverse of e. The calculated inverse will be called as d.
Algorithms for generating RSA keys
We need two primary algorithms for generating RSA keys using Python − Cryptomath module and Rabin Miller module.
