the export ciphers don't get added by default. you need to explicitly add them. off of the top of my head i don't remember the exact function to add cipher suites, but if you poke around the docs a bit you'll find it. --keith Keit

Re: SSL-40bit : Attack-Scenario

What you're basically saying is that if someone can sniff packets, and brute force their way into decrypting the information, is their data safe, and is this a possible scenario. No, their data won't be safe. Yes, this is possible. There are plenty of studies that have shown how much computing po

Problems with my server and 40 bit browsers

Hi, We have developed our own web server and recently upgraded to SSL 3.0 using SSLeay 0.8.1. We have noticed that web browsers with a cipher strength of 40 bits cannot connect to our server while web browsers with a cipher strength of 128 bits can. Any help in debugging why this is happening

Hi, I would enjoy hearing some opinions on the following potential scenario : The SSL-Client does no client-auth. and has to transmit one string, that contains security-sensitive data. Let's think of a man-in-the-middle you leaves through the handshake-packets, but blocks the data-packets. He th

Hi, I've been able to get Crypt::SSleay to compile with SSLeay v8 and v9, but I had to modify the source a bit to get it to work. If you want, I can hunt down my mod's that made it possible. Assuming that OpenSSL is just the later version of SSLeay (?), what do you all think if I updated Crypt
