[AccessD] Hash MD5 (Crypto) (was: OT- I am a luckywinner??)

Bryan,

I just wanted to say thanks for pointing me to this site.  I have imported
into my framework the MD5 class as well as two of the registration key
generators.

I have been looking for some way to generate a unique ID like a SSN given
the lack of an SSN. The MD5 applied to an append of the lastname & firstname
& Phone (or something like that) will give me a unique identifier to use to
prevent duplicates and so forth.

The registration key classes likewise give me a new view of copy protection.

Thanks again,

John W. Colby

The VB6 class for MD5 is drop and go, IIRC.

To use it all you need to do is:

Dim md5 As CMD5
Dim strEncrypted as String

Set md5 = New CMD5
strEncrypted = md5.md5("PlainTextToEncrypt")

That's all there is too it.

Actually this sounds like a better option than the one I'm using.  As I
need to
put a dll in the system path.  (not referenced directly thankfully)

I might take a look at this (and the other hash algorithm on this site)
and see
about converting to access.  (assuming its not drop in and play)
