Netscape 4.51 crashes with Client Certs
We have a very perplexing problem... We are implementing a CA (using OpenSSL 0.9.4, apache 1.3.9, and mod_ssl-2.4.10-1.3.9) and our users are using Netscape 4.51 (no upgrade option currently exists for them). They can successfully generate a certificate request which is delivered to our CA which we can successfully sign and then make the resulting certificate available for pick-up. The users are then able to retrieve the certificate, which is then visible as a personal certificate and validates properly when the Verify button is pressed. Everything is fine so far ... BUT, when they visit the site which requires client certificates, Netscape crashes. Looking at the apache/mod_ssl trace logs it appears that the initial SSL handshake completes. The server then requests a client cert and no further communication is received. It would appear that Netscape is crashing when parsing the certificates to display the certificate choices to the user. If we export the certificate from Netscape and import it into Internet Explorer, it works as expected... Anyone have any ideas??

RE: Multiple threads handling one connection
Hi, I sent the message below last week, asking about multiple threads accessing a single SSL connection, but didn't receive any replies. I can't find anything relating to this on the list archives. Has anyone tried this, or is it not supported? Thanks Ollie King Data Connection Ltd. -Original Message- From: Oliver King Sent: Thursday, February 10, 2000 10:33 AM To: '[EMAIL PROTECTED]' Subject: Multiple threads handling one connection Hi all, I've seen (and written) test programs that drive a number of SSL connections from multiple threads, but none of them seem to drive a single connection from more than one thread. Does OpenSSL support reading from a connection on one thread and writing to the same connection on another thread? I wrote a simple test app to try this using non-blocking sockets and it seems to work, but rather than rely entirely on my test I'd like to have a more definitive answer as to whether or not this is acceptable. If it turns out that this is a Bad Thing to do, what's the recommended alternative?

Re: How to build OpenSSL license free?
hi, I didnt know that i should remove RC5, IDEA, RSA from the crypto directorie to avoid license/patent problems before commercially shipping apache-openssl. I thought the only problem is while linking in the rsaref library. I have license for bsafe and i am linking in bsafe library instead of rsaref library.

Netscape doesn't like certain certificates. There's no obvious pattern but things like '' or '-' characters in them can stuff things up. I suggest you try with different CA and/or client certificates. Start with something simple and see how much it will tolerate. Keep a PKCS#12 file for a broken certificate though: it may be useful when there's enough of the communicator security source around to diagnose some of these things. Steve. -- Dr Stephen N.

Re: rc2 encryption with 128 bit key
Hi, I think the problem lies with the browser. The browser seems to be an export version so strong encryption algorithms have been disabled. This means that in the client_hello the browser's list of available ciphers will be null and so the connection fails. What you could do is run openssl tool s_server in the debug mode and actually find out the cipher list that the browser sends to the server. :) Amit. vijay karthik wrote: Hi! I selected the "RC2/RC4 encryption with 128 bit key" cipher for SSL connection from my browser. I tried to connect to the apache listener(with openssl), and it fails to connect. whereas RC2/RC4 with 40bit key succeeds. Does this mean the apache server is a 40 bit server ? Is there anything i should do during the Build, to get a 128 bit apache-openssl server ? Is there a way of finding out if the server i am using is a 40 bit or 128 bit one ? thanks Vijay __ Do You Yahoo!? Talk to your friends online with Yahoo!
