Hi all, Eric, Iīve read your book and run examples in it but I do have a problem with them (with your examples, not your book). They donīt validate certificates, donīt verify if they are valid (even the simplest thing: validate dates). What I want (and need to) is construct a very simple client application (that supports only SSLv3 and RC4-MD5 and EXP-RC4-MD5) that connects a server and *before* send or receive any data validates servers certificate based upon a list of CAs. Iīve tried to use the command "openssl s_client -verify 5 -ssl3 -connect www.someURL.com:443 -cipher RC4-MD5 -CApath my_CA_path -no_ssl2 -no_tls1" but there are some messages (that I guess are errors) I can't understand, e.g., a successful verify operation must return 0 or 1? Can you help me?
