Hello Tom, GlobalID, step up or server gated cryptography only may be required when using (old) exportable client software: first the client offers the server a exportable cipher suite; when the server sents a special "step-up" certificate (issued by Verisign) the client recognizes that the server is allowed to use a strong cipher suite and starts a renegotiation handshake to switch to the new cipher suite. If the client uses strong cipher suites by default, step-up cryptography may not be required. Please look at http://jcewww.iaik.tu-graz.ac.at/products/isasilk/documentation/interoperabi lity/index.php (last sections) for using server gated cryptography with iSaSiLk .

April 2002 12:42 An: iaik-ssl@iaik.at Betreff: [iaik-ssl]cu|| 40 vs. 128 bit certificate question Hi, I'm trying to figure out what the (technical) difference is between a 40 and 128 bit certificate, like verisign is selling. What is the actual difference between a "40-bit SSL Secure Server ID" certificate and a "128-bit SSL Global Server ID" certificate. As far as I know, there is no such thing as a keylength limitation in a certificate. When my server application supports 128 bit encryption, and my client application, too, I don't think that my 40-bit verisign server cert can prevent the use of 128 bit keys? In other words, why should I buy a 128 bits cert, which is more than twice as expensive as a 40 bit cert. Can anybody clarify these things to me?
