Description of problem:

Configured heat setup as mentioned in 
http://openstack.redhat.com/Deploy_Heat_and_launch_your_first_Application

After the setup is done, whenever heat-engine is run, below error is seen in the heat-engine logs.
 heat.openstack.common.loopingcall EVPError: bad decrypt
Complete error logs are mentioned at the end of description.

Autoscale up of VMs is not happening due to this.

Tested the same after setting up heat from sources and autoscaling is working fine. The main difference between two setups is the use of cryptography module.
In RDO, M2Crypto is used due to which might be the cause for the above mentioned error. In openstack main stream code, pycrypto is used and there is no error in heat-engine logs.

How reproducible:


Steps to Reproduce:
1. Configure heat setup as mentioned in 
http://openstack.redhat.com/Deploy_Heat_and_launch_your_first_Application

2. After the setup is done, run heat-engine in background. 
3. Check the heat-engine logs for the below error.
 heat.openstack.common.loopingcall EVPError: bad decrypt


Actual results:

Below error is seen in  heat-engine logs.
 heat.openstack.common.loopingcall EVPError: bad decrypt

Expected results:
No errors should be seen in heat-engine logs.
