How to encrypt data in Python 3.3?

Question

Python

Hello. I have the following problem - I need to encrypt strings on Paython. It's just that XOR is not very appropriate in this case, so I tried to google AES or Blowfish. But unfortunately the PyCrypto library is written in an old version of Python, blowfish too. Can anyone suggest data encryption libraries for Python 3.3?

Answer 1

PyCrypto supports python 3.3.
https://pypi.python.org/pypi/pycrypto
Maybe your Windows didn't build right away because of stackoverflow.com/questions/13787258/pycrypto-inst... ? But there the solution is indicated (either take an untrusted binary from the Internet, or collect it from under mingw).
If it doesn't work - then try bindings to OpenSSL (pyOpenSSL https://github.com/pyca/pyopenssl )

Answer 2

If it’s still relevant to help others, try simple RSA in Python
https://pypi.python.org/pypi/rsa
After downloading, let’s start encryption:

import rsa
(pubkey, privkey) = rsa.newkeys(512)
 
message = b'Hello Blablacode.ru!'
 
# шифруем
crypto = rsa.encrypt(message, pubkey)
print(crypto)
#расшифровываем
message = rsa.decrypt(crypto, privkey)
print(message)

You don't need to generate a key pair every time. You just need to keep them in a convenient place.
Program output:

$ python3 rsa_test.py
b'\x19\xd1\xbb\xf8N\xb7\xa8F\xf2\x19\xaa\xd1\x17\x868\xbcn\xc8\x85\xd4r\x81\xdaK\x0f\x80\xee1P\xdd\xdcV5\xed\x12\xf6S\x7f\xd7&f\x9e\xdawC\x038\xbb\xbaX\x8ae\x18\xeaR\x12E\r\x90\xc5c\x18\xd4\r'
b'Hello Blablacode.ru!'

You can try cryptography .

Nothing worked with PyCrypto on Mac. error: no commands supplied.

C Cryptography is the same crap. You need Homebrew first, then Pip, then you can only install. I installed homebrew, but problems with pip. I advise you to install it through Python. Now I have 3 pythons installed on a Mac with 128 GB. Funny.
As a result, I decided to limit myself to this - habrahabr.ru/post/212235
And nothing came of it either.
If someone will tell me a working library (and preferably even 1 script) that allows you to encrypt data, I will be very grateful
