the trouble is, there is another package called Crypto and a lot of folks install that first. and it doesn't work. `pycrypto` is the right package.. I wonder if the command ought to be changed for disambiguation? `from pycryto.Cipher..` never seen this divergence from naming convention with other packages. — Nikhil VJ, Mar 31 '18 at 13:53

I've installed it. Used : pip install pycrypto. – AK1992 Jun 09 '15 at 18:08
I guess you've tried to import "import crypto" But in docs,it shows like that "from Crypto.Cipher import AES" – Jun 09 '15 at 20:51
Solved it . Had to change the name from crypto to Crypto. Thank you ! – AK1992 Jun 09 '15 at 22:14
There is another Crypto package that we end up installing instead of pycrypto. There should be a way to disambiguate.. module name to use in code ought to mirror the official name of the module. – Nikhil VJ Mar 31 '18 at 13:56

I get an error saying `ImportError: cannot import name Padding` whenever I type `from Crypto.Util import Padding`. I observed that the Padding file is not present in Util. How do I find a pycrypto package with Padding in Util – thegreatcoder Oct 20 '18 at 03:00
