CFML - Parse a String - Find Variables - coldfusion

Question

I know this is fairly simple. But I can't find my cut paste code or something that works.
I am encrypting a string.
<cfset encrlink = encrypt("uid=WWWDDD&email=BOBEMAIL#BOB.COM", APPLICATION.AesKeyForMails, "AES", "HEX")>
Which works fine. And then I decrypt it.
<cfset dncrlink = decrypt("#encrlink#", APPLICATION.AesKeyForMails, "AES", "HEX")>
<cfoutput>[#dncrlink#]</cfoutput>
Which works fine. Gives out "uid=WWWDDD&email=BOBEMAIL#BOB.COM"
I need to get "uid=" and "email=" out and use as variables of the decrypted string. By parsing. I'm just a bit stuck. Is it Trim? Find? I kinda have this working. But not sure how to build the cfset.
<cfoutput>
<cfset theUrl = "#dncrlink#" />
<cfloop list="#theUrl#" index="URLPiece" delimiters="&">
<br>#listFirst(urlPiece, "=")# = #listLast(urlPiece, "=")# <br>
</cfloop>
</cfoutput>

Answer 1

I was able to do a CFIF for the Variables.
<cfloop list="#theUrl#" index="URLPiece" delimiters="&">
<br>#listFirst(urlPiece, "=")# = #listLast(urlPiece, "=")# <br>
<cfif #listFirst(urlPiece, "=")# is "uid"><cfset uid = "#listLast(urlPiece, "=")#"></cfif>
<cfif #listFirst(urlPiece, "=")# is "email"><cfset email = "#listLast(urlPiece, "=")#"></cfif>
</cfloop>

Too long for comments ...
You could also "genericize" the logic into something which could be used with any query string. Extract the parameters and store them in a structure
<cfset dncrlink = "uid=WWWDDD&email=BOBEMAIL#BOB.COM">
<cfset params = {}>
<cfloop list="#dncrlink#" index="elem" delimiters="&">
<cfset params[ elem.listFirst("=") ] = elem.listRest("=")>
</cfloop>
Then to access parameter values:
<cfoutput>
uid = #params.uid#<br>
email = #params.email#<br>
</cfoutput>
