You are asking about encryption which is covered very well in the latest CFDJ article by Wayne Graham. It includes step by step implementation.
The areticle is here: http://www.sys-con.com/story/?storyid=46359&DE=1#RES (scroll down to 2nd page for article) You can make calls like: encrypted = encrypted(password,symmetricKey); decrypted = decrypted(encrypted,symmetricKey); Ryan Duckworth Macromedia ColdFusion Certified Professional Uhlig Communications 10983 Granada Lane Overland Park, KS 66211 (913) 754-4272 -----Original Message----- From: Richard Meredith-Hardy [mailto:[EMAIL PROTECTED] Sent: Thursday, October 21, 2004 10:26 AM To: CF-Talk Subject: what is it called..? ...when you have a value eg 22 which is made up of 2+4+16 so you know of all your options valued 2,4,8,16,32 Etc only 2 and 4 and 16 apply. I know there must be a mathematical name for this, but what? Does anyone have some example CF code to 'decrypt' such numbers? Are there other [simple] ways to do this to handle a large number of options (>25, so I don't start having giant numbers?) Something to do with prime numbers perhaps? You can tell I'm not a mathmatician can't you!
