Hello all,
--
I'm trying to speed up the initialization of a legacy HTTP client application. Debugging that code, I found the following functions being called each application startup:
initialization
SSL_library_init()
SSL_load_error_strings()
OpenSSL_add_all_algorithms()
RAND_screen()
however, the execution of RAND_screen() spends about 3 seconds.
The first idea was commenting this line, but I don't know if I really can do that. After some "googling" I found someone doing something like this:
initialization
SSL_library_init()
SSL_load_error_strings()
OpenSSL_add_all_algorithms()
//RAND_screen()
unsigned char c;
RAND_bytes(&c, 1);
anyway I don't know if it is really necessary, so I just commented RAND_screen() line and without add this call to RAND_bytes().
So I have a question: do I really need to call some function like RAND_* at each application initialization?
This project has that same initialization: https://github.com/svn2github/Ararat-Synapse/blob/master/trunk/ssl_openssl_lib.pas#L2001 .
