socket.ssl with key files?

[Chris Curvey]

I need to use socket.ssl() to open a connection using key files. I
have been provided with a text file called cert_key_pem.txt containing
my keys that looks like this:

-----BEGIN RSA PRIVATE KEY-----
MIICXgIBAAKBgQDKwLuk/UpICOnZvH3mf9rFQvCkDPA8XQZLpa80Z0liMVYu4GQT
<snip>
-----END RSA PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
MIICkTCCAfqgAwIBAgICNqUwDQYJKoZIhvcNAQEFBQAwgZ8xCzAJBgNVBAYTAlVT
<snip>
-----END CERTIFICATE-----

I see that socket.ssl takes "keyfile" and "certfile" parameters. So do
I just take the text file that I've been given and break it into two
files, then specify those file names when I open the connection? At
the moment, I'm getting

File "/usr/local/lib/python2.4/httplib.py", line 1070, in connect
ssl = socket.ssl(sock, self.key_file, self.cert_file)
File "/usr/local/lib/python2.4/socket.py", line 74, in ssl
return _realssl(sock, keyfile, certfile)
socket.sslerror: (1, 'error:14094410:SSL routines:SSL3_READ_BYTES:sslv3
alert handshake failure')

Many thanks for any ideas!

This might help, or it might not. If you have a passphrase on the
private key, somehow the passphrase needs to be provided as well,
but I'm unsure how.

This code is mostly untested, so you might have to modify _ssl.c
as well to make it work.

thanks for the info.

1) Am I correct that I should just be splitting the files?
2) The passphrase question was in the back of my mind, but I guess I
need to move it to the front. Hopefully someone here will have an
idea. (I wonder if M2Crypto handles that?)

I guess it's better to know that the code is fairly untested, rather
than finding that out on my own.

Nobody knows. Just try it and report whether it works.

Rats, you beat me to it.

It seems to work if I just give the same, combined file as the argument
to both the key_file and cert_file parameters. (that's not to say that
it doesn't work if I do something else).

In my case, the passphrase is packaged up in the xml payload and sent
over.

Thank you everyone.
