[Vol-users] Error on Pycrypto

Dear all, I am Andri Heriyanto. I am just starting to use Volatility as the tools for analyzing the memory. I am using Python-2.7.3 and already installed Volatility ver 2.1 on both OS: Windows 7 64-bit and Linux Ubuntu 12.04 LTS 32-bit, unfortunately I could not resolve the problem on pycrypto. Especially on the Linux Ubuntu 12.04 LTS, there is always a notification of an error like this: ERROR : root : code for hash sha224 was not found. Traceback (most recent call last): File "/usr/local/lib/python2.7/hashlib.py", line 139, in <module> globals()[__func_name] = __get_hash(__func_name) File "/usr/local/lib/python2.7/hashlib.py", line 91, in __get_builtin_constructor raise ValueError('unsupported hash type %s' % name) ValueError: unsupported hash type sha224 ERROR : root : code for hash sha256 was not found.

Thank you very much in advance for any support and suggestion. Cheers
