Any good examples on programming using libssl? [closed]

Question

I was wondering whether someone knows any good examples on using libssl as a programming library. Its kind of annoying only digging through the code of libssl trying to make sense of it. In the worst case I'll just keep going @ try and error.

Answer 1

You've run into the lack of documentation problem OpenSSL has. IBM DeveloperWorks does have a couple articles about using OpenSSL:

• http://www.ibm.com/developerworks/linux/library/l-openssl.html
• http://www.ibm.com/developerworks/linux/library/l-openssl2.html
• http://www.ibm.com/developerworks/linux/library/l-openssl3.html

If you want to utilize a better documented library, you can take a look at Mozilla NSS:

• http://www.mozilla.org/projects/security/pki/nss/#documentation

Answer 2

Just that I'm using Openssl too and think their wiki page also has some good info: http://wiki.openssl.org/index.php/Main_Page

Answer 3

Here is a good working example that's especially useful for iOS developers:

the remail email client uses MailCore iOS email library wrapper, which in turn uses the multi-purpose libetpan email library, which in turn uses SASL, an authentication layer, which in turn uses your beloved openSSL.

So if you're a believer in the learn-by-example methodology, the above gives you a lot to work with and practice on.
