I’m trying to activate our enterprise license on a Linux server in the CF admin portal, but got this error:

errorAn error occurred while trying to encrypt or decrypt your input string: Given final block not properly padded. Such issues can arise if a bad key is used during decryption..

Any advice?

Thanks,

I've seen errors of that sort, with other than the license activation feature, when the json being parsed as some response was incorrect.

Look at cf's logs, immediately after attempting that activation, to see what additional detail they may offer. Indeed, you may even find that attempting it again may just work, if the problem was just a temporary one.

If neither suggestion helps, email cfinstal@adobe.com to get more direct help from them.

I just thought of two more possibilities. First, look at that json file you're trying to use (cat, less, nano--but don't change it in any way). Does it look like pure json? If not, perhaps there was a mistake in the process of downloading that from Adobe or getting it to you, to use for this activation.

Second, confirm what user is running cf. You can view that with top, Ps, etc. Ensure that user has read access to that /opt folder you're pointing to.

Better still, just put the file in the cf folder (which may be /opt/coldfusion2025. CF will of course definitely have read access to that.
