Albert,

Yes I use the single function call. It wasn't obvious ( for me ;-) ) but testing revealed that the result was correct with the single function call. I have a question related to this subject. I am using your MD5() function to generate fingerprints for files that we import into SQL Server. This allows us to very quickly detect if a given file has already been imported. So far I've been using the code from the wiki. I'm wondering if I could use the single function call MD5()? What's the difference between these two methods?

Thanks again for this great utility!

>>I just found a solution. Albert Ballinger's great utility FoxCrypto.fll (see http://fox.wikis.com/wc.dll?Wiki~FoxCrypto~VFP) has a function called HexEncoder which does exactly this. This function is soooooo fast. My StrToHex() version written in VFP took 127 seconds to convert a 180KB file. Albert's function does it in 0.1 second!!!
