Question

I am porting opera recovery from already existing C++ code

http://pastebin.com/ViPf0yn6

I struck at this function

MD5(tmpBuffer, sizeof(opera_salt) + DES_KEY_SZ, hashSignature1);

Where can I get that MD5 unit?

steve0, the code in your link reference to the md5 openssl implementation, you can find the original declaration of the MD5 function used in the code in this link

 unsigned char *MD5(const unsigned char *d, unsigned long n, unsigned char *md);

you can use the MessageDigest_5 (since Delphi 2007) unit to calculate the md5 for a buffer or the TIdHashMessageDigest5 class from the indy components.
