Martin and John, Thank you both for your replies Must I have OpenSSL imported in my Python program? So far I have been using only SSL support. Built-in SSL support works OK if I connect from my Python program directly to SSL server ( but not via proxy). L. -- http://mail.python.org/mailman/lis

Thank you all for your replies. I am still a newbie with SSL issues but I found out that: a certificate that is signed by OpenSSL's own CA( certification authority), that is not recognized in the program's list of root CAs, causes an exception to be raised. (That is a different behaviour from the
