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

Python Generate Random Aes Keys
@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 |

Encrypt & Decrypt using PyCrypto AES 256 (6)
Another take on this (heavily derived from solutions above) but
- uses null for padding
- does not use lambda (never been a fan)
- tested with python 2.7 and 3.6.5
I'm trying to build two functions using PyCrypto that accept two parameters: the message and the key, and then encrypt/decrypt the message.
I found several links on the web to help me out, but each one of them has flaws:
This one at codekoala uses os.urandom, which is discouraged by PyCrypto.
Moreover, the key I give to the function is not guaranteed to have the exact length expected. What can I do to make that happen ?
Also, there are several modes, which one is recommended? I don't know what to use :/
Finally, what exactly is the IV? Can I provide a different IV for encrypting and decrypting, or will this return in a different result?
Here's what I've done so far:
For someone who would like to use urlsafe_b64encode and urlsafe_b64decode, here are the version that're working for me (after spending some time with the unicode issue)
