Jimmy, You could md5 something and send it encrypted and then verify the md5, something similar to sharing keys...md5 is similar to a key...i use it as something similar to kerberos...
And yes, MD5 is a one-way hash...which comes in handy... Just remember that bigger is almost always better. I would suggest trying all three (blocksize, keylength, and both) and see which one works best for you. You should see how your system deals with it and then decide...I like to have bigger keylenghts personally...

Part 2 Thanx for the suggestions! Someone mentioned that I could use MD5 and then encrypt the hash, how would I ever decrypt that? Is'nt MD5 a 1-way thing only? Another question? Should I go for bigger keylength or bigger blocksize or both? What makes for the best encryption? / Jim (and before someone suggest that I read the book Applied cryptography it's already orderd and on it's way :-) ) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
