Just a wild guess: If you click on edit trust on the root certificate in Firefox, you have to tick the box for web server certificates. cheers Mat On Friday 04. October 2013 21:29:57 you wrote: Hello, there exists a self signed root CA certificate (A) one intermediate CA certificate (B)

openSSL performance

2013-10-07 Thread laurent . bollini
Hello, I'm using openSSL on a low-end embedded processor: an Intel Atom running at 1.1Ghz.Using SSL divides down my transfer speed by two so I try to figure out how I can improve performance. For information I'm using 1.0.1e release, recompiled for Win32 (my embedded system uses an XP embedded)

Server Certificate verification against available fingerprint

2013-10-07 Thread Manoj
Hi,I am a newbie to openssl, I do have a question related to client hello/server hello authentication flow in openssl.I have to use pre-available fingerprint to verify the server certificate during TLS connection establishment.Is there any way/mechanism in openssl to verify certificate against

Are you sure that the key exchange is not a factor? Have you measured SSL setup times compared to post-setup transfer times? 4K RSA is computationally expensive. Are you sure that the rest of your system is secure enough to justify that instead of 2K RSA? /r$ -- Principal

RSA key size only affects handshake, and should be costly client side only if using client-auth; are you? Data handling speed will normally be affected by encryption *and* MAC (usually HMAC). You could certainly try different data (symmetric) cipher, such as 3DES or RC4. I don’t know
