title: RSA Encryption/decryption within windows crypto library dll?
body: <p>I'm in a situation that I need to use AES-256, SHA1,2 and RSA, but these functions need to be loaded from an intrinsic windows dll file (something like cryptoAPI in advapi32.dll, which can be found in C:\Windows\system32).</p>
  
  <p>I've found almost everything I need in advapi32.dll except RSA encryption. So,do you know any other crypto libraries from windows (XP2 should be supported)?</p>
  
  <p>In the worst case, any free external crypto library in dll format is appreciated.</p>
