Python 2.6 SSL module: Fails on key file error, with Errno 336265225,without a key file.
I'm starting to convert from M2Crypto to Python 2.6's SSL
module. So I tried a trivial test:
certs = "d:/projects/sitetruth/certificates/cacert.pem"
sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ssk = ssl.wrap_socket(sk, certfile=certs, cert_reqs=ssl.CERT_NONE)
This is a basic HTTPS open sequence.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "D:\python26\lib\ssl.py", line 307, in connect
ssl.SSLError: [Errno 336265225] _ssl.c:337:
error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib
The cert file is the same PEM file I use with M2Crypto, and it's
derived from Firefox's cert file.
Why am I getting a "private key" related error? I'm not submitting a keyfile,
just a cert file.
I've tried explicitly adding "keyfile=None" to the wrap_socket call, but
that doesn't change anything.

I'm not an expert but this is what the SSL doc says:
Â« The keyfile and certfile parameters specify optional files which
contain a certificate to be used to identify the local side of the

and that one of them (probably the keyfile) needs to be a private key.
Otherwise how would the local side identify itself?
Perhaps you are using the wrong parameters and looking for ca_certs
Â« The ca_certs file contains a set of concatenated â€ścertification
authorityâ€ť certificates, which are used to validate certificates passed
from the other end of the connection. Â»

That's right. Thanks.
