There are manual pages included in every distribution which describe the API quite extensively: look under the docs directory. Those for the bleeding egde development version are also available online too, see: http://www.openssl.org/docs/ the API doesn't change that much so those will be largely accurate for older versions of OpenSSL. The examples at the bottom of some pages can help and sometimes include code snippets. There are also some very basic sample programs under demos/ in each distribution. > I'm aiming to eventually develop a secure messaging system, but I'm > completely new to cryptography and OpenSSL (I still need guides to > walk me through generating keys, and I don't fully understand which > keys fit which "locks"...). > Well you wont find a cryptography tutorial in OpenSSL.
