Alternate RAND_poll for XP/2003 Server/Vista

[Adrià Massanet]

Hi all,   I’m using OpenSSL as a module in PHP (php_openssl), and I need to call the CGI page may times per second  but the initialization process in RAND_poll is too slow.   I’m thinking to modify OpenSSL to use the rtlGenRandom call available in XP/2003 Server/Vista OSs (see http://blogs.msdn.com/michael_howard/archive/2005/01/14/353379.aspx for comments on rtlGenRandom )   the new function likes:     int RAND_poll() { if_any_error_in_block_return_old_RAND_poll() {   HMODULE hlib; BOOLEAN (APIENTRY *rtlgenrandom)(void*, ULONG); char buffer[1024]; int c;   hlib=(HMODULE)LoadLibrary("ADVAPI32.DLL"); tlgenrandom=(BOOLEAN (APIENTRY *)(void*,ULONG))GetProcAddress(hlib,"SystemFunction036"); for(c=0;c<1+(ENTROPY_NEEDED/sizeof(buffer));++c) {             rtlgenrandom(buffer,sizeof(buffer)):             RAND_add(buffer,sizeof(buffer),sizeof(buffer)); }               } }   a bad idea? Any thing bad here?   Thanks in advance,   Adrià
