I think you'd need multiple classes. For things done once a program life time, a C++ class (singleton) may not be suited, a simple ordinary init function may be sufficient. However, such an instance could make sense for instance if used on stack around main in something like this: int main() { OpenSSLAllEverything allocation; return main_(); } to ensure that it is released exactly once even in case of exceptions. Maybe the class assert()s that it is constructed only once to help application developers to find usage problems quickly. I think it is essential and required to call RAND_seed once and only once.

Maybe having a static instance counter, so resources could be freed if the last instance is destroyed? But to much automagic handling may not be good; imagine, this would be linked with a similar class that also has its own instance counter... oki, Steffen About Ingenico Throughout the world businesses rely on Ingenico for secure and expedient electronic transaction acceptance.
