Tracy, George and Chen,

I'm starting to use CryptPack, which you can download at
http://milan.jikos.cz/CryptPak/

As the readme says, it can:
ENCRYPT/DECRYPT - encrypts/decrypts string using strong BlowFish encryption algorithm
SHA1 - calculate SHA1 messsage digest for string passed as parameter
MD5 - calculate MD5 messsage digest for string passed as parameter
CRC32 - calculate 32-bit CRC (SYS(2007) calculates 16-bit CRC)

BTW, i have give up on my idea of using MD5 instead of encryption for passwords. The reason is that MD5 creates always the same string from a source string, and if someone looks into the DBF and extracts the MD5 string he can try thousands of source strings until he will surely find the right one (aided with a fast machine and dictionaries I don't think it will take too long).

Regards,
Javier.

PD: thanks to Milan Kosina for writing CryptPack and giving it for free.

>>I am wondering how can one incorporate MD5 or the like technology into a VFP application. Is there a class or component ready to be used in a VFP application so that keys can be generated and records be signed? I really need this function in my application but am not sure the best approach. TIA
