Description of problem:
Contrary to the documentation EVP_DecryptInit coredumps if the EVP context is
not initialized.

openssl-0.9.7-3

The OpenSSL team reports that this bug was fixed a couple of weeks ago.

Also received the following oneliner which from another user:

    initialized 

I haven't checked, but this may already be fixed in the latest source.  In any
case, there's a one-line fix (I ran into the same problem): change
EVP_DecryptInit() so that it calls EVP_CipherInit() rather than
EVP_CipherInit_Ex().

And the OpenSSL team response to this fix was:

Agreed, fix being checked in. Thanks for the report.

This was fixed a couple of weeks back. The fix is in any 0.9.7 stable
snapshot and will appear in 0.9.7.
