Problems with decrypt. Any Thoughts?

I am using encrypt and decrypt on my site. Encrypt works fine. When I decrypt I get the following error.

Lucee 5.0.0.254 Error (java.lang.ArrayIndexOutOfBoundsException)

This is the code I have written…

<cfset thiscode = “works”>
<cfset codetest = encrypt(thiscode, ‘123456’)>
<cfoutput> #thiscode# - #codetest#</cfoutput>
<cfset codetest = decrypt( thiscode, ‘123456’)>
<cfoutput> #thiscode# - #codetest#</cfoutput>

Thank you

<cfset codetest = decrypt( thiscode, '123456')>

thiscode isn’t encrypted so decrypt can’t decrypt it.

Change it as follows (I changed your variable names so you can follow the path from plaintext to decrypted plaintext):

<cfset originalPlaintext = "works">
<cfset encryptedText = encrypt( originalPlaintext, '123456')>
<cfoutput>#originalPlaintext# - #encryptedText#</cfoutput>
<cfset decryptedPlainText = decrypt( encryptedText, '123456')>
<cfoutput>#originalPlaintext# - #decryptedPlainText#</cfoutput>

I am in idiot. Thank you!

We’ve all been there. More than once.

I see the error in the code you have pointed out @Juan_Aguilar, however, do you think that should cause the code to error? I feel like it would be more sensible for it to return a blank string or something to indicate it couldn’t decrypt it.
