Hello, AES256-SHA means also RSA key_exchange. Are you setting private RSA keys, certificate, and CA certificate also in SSL context ? does this imply that when I want to use EDH for key exchange that the cipher will not be able to be AES*? No, AES encryption may be used with the

Hello, Hi, fellows. Thanks a lot for the hint. I'm using Blowfish in cfb mode. Will there be any padding not removed problem with this cipher? Actually I'm very new here. I wonder if anyone can also clarify to me some basic concepts as well. I really appreciate the help. 1) What

Hello, 3) In enc manpage, what does a salt mean? In openssl enc passphrase and salt are parameters to PKCS#5-like key generation function. You may read more about PKCS#5 at: http://www.rsasecurity.com/rsalabs/node.asp?id=2127 4) Suppose I have an input file foo.in and a key file

SSL renegotiation

Dear all, I'd need a little clarification on SSL renegotiation. Could ssl renegotiation take place over a different tcp port then the already-established ones ? (tcp connections established, handshake succcessfully performerd at least one time). I noticed the custom server application I have

Im not sure if SSL gives u such options, but the best way to prevent compromise of a RSA key would be to establish a diffie hellman key. You would want to do a shared secret anyawy..and im sure SSL does it..if the shared secret is computed using diffie hellman and nobody gets hold of the

Related note: you can explicitly request re-keying at any time, and should do it periodically on long-term connections. That makes analysis even more expensive since there's less data and less payoff. Victor Duchovni wrote: For all these ciphers the attacker has to brute force the symmetric

On OS X you can use pstopdf... a couple of ideas can be found here: http://www.macosxhints.com/article.php? story=20051020122911920query=man+pdf Basic usage is: man -t openssl | pstopdf -i -o openssl.pdf That will give you a formatted PDF for two sided printing. On May 25, 2006, at 6:17 PM,
