How to resolve the error “CTR mode needs counter parameter, not IV” on CentOS?

Error CTR mode needs counter parameter, not IV occurs on the CentOS operating system if the pycrypto package is installed through the system manager from the python2-crypto-2.6.1-15.el7.x86_64.rpm package.

For elimination you need to:

  1. Delete directory /usr/lib64/python2.7/site-packages/Crypto/.

  2. Install pycrypto package using the package management system pip:

    pip install pycrypto==2.6.1
