Does not work on CentOS

[mikeover]

I did yum install python-crypto python-requests. Python-crypto installed but python-requests said No Package found.

Then when running pythong test-decrypt.py I get: Traceback (most recent call last): File "test-decrypt.py", line 5, in from Crypto.Cipher import PKCS1_v1_5 ImportError: cannot import name PKCS1_v1_5

Please advise how to run this on CentOS. Thanks.
