title: is cryptoapi good?
body: <p>i'm writing a crypto program that does stuff like hashing (sha1), encryption, digital signatues for win32 in c++
  is built in cryptoapi secure, or should i use some other library like crypto++
  i need maximum security and works on all systems xp and vista (and optionally 2000), but at same time i need to minimize exe size and so don't want uneeded external libs</p>
