Decrypting A String of Numbers Using ColdFusion decrypt tag
Hi Experts,
I'm trying to write a script that will take a 20 digit string of base10 numbers (e.g., 1234-5678-9012-3456-7890) that is encrypted from an 18 digit base10 number (e.g., 123456789012345678) and decrypt back to the original 18 digit number. The 18digit number was encoded with 3DES (DESEDE). The three keys are in hex (e.g., key1=4e4e4e4e4e4e4e4e, key2=4e4e4e4e4e4e4e4e, key3=4e4e4e4e4e4e4e4e - yes I'm aware; this set of keys makes it very insecure and equivalent to single DES, it's just for example). My thinking was that the following code would work, but I was wrong. I'm guessing I have a simple syntax problem or it's passing a bad format and the hex number is not being recognized as an actual hex number, so it may be just setting the variable correctly as a hex that will fixit... Please help and thank you in advance!!

<cfset MyString="12345678901234567890"> *Note: the 20 dig encrypted base 10 number
<cfset MyKey="4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e4e">
<cfset decrypted_text= decrypt(MyString, MyKey, "DESEDE","HEX")>
<CFOUTPUT>#decrypted_text#

and... u have to put ## signs
<cfset decrypted_text=# decrypt(MyString, MyKey, "DESEDE","HEX")#>
<cfset decrypted_text=# decrypt(MyString, MyKey, "DESEDE","HEX")#>

I agree, you don't need hash marks ('#') to declare the var. The inputbasen function didn't work either, it gave me a "must input a valid base 16 number" error. Thoughts?

Oh and no, the encoding formula I don't have...
Web Servers
A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

<cfset theKey= "CFMX_COMPAT">
<cfset myEncoding = "Base64" >
<cfset eC=#Encryptform.name,theKe
and the variable eC is encrypted
in the same way u can decrypt
<cfset eC2= #Decrypt(form.name,theKey,
try this hope it helps u..
