[Python] ValueError: unsupported hash type

[jwoger_splunk]

I have found that on some of my instances and later versions of splunk that have version 2.7 of Python bundled, when trying to execute my python scripts using splunk's bundled python libraries, i get the following error and the script does not execute.

"/Applications/splunk6.2/splunk/lib/python2.7/hashlib.py", line 139, in <module>
    globals()[__func_name] = __get_hash(__func_name)

    raise ValueError('unsupported hash type ' + name)

How can i fix this error?

I marked this as a "me too", however, it seems that while python dumps out these messages, the script continues on and does what it is supposed to do. So, it's just noise rather than broken for me.

This is because The python2.7 package is dependent to the libssl1_0_0 package (openssl_1.0 runtime librairies). Your OS is missing these. Install them and it will get rid of this error.

Wouldn't using openssl_1.0, make you vulnerable to "Heartbleed"?

Yes. A better answer would be "just don't do anything ssl-related with splunk's built-in python"
