What is the issue you’re encountering

Verification of Turnstile Site Key returns true when adding additional characters to site key

What are the steps to reproduce the issue?

When verifying a site key and pasting the key from Cloudflare; it verifies successfully
When adding another character say 1 to the end of the key, it verifies successfully still

I am going to be asking users for their own keys for a service I’m providing as part of a site builder.

I assume that when verifying the key Turnstile is LEFT(24) as that appears to be the length of the keys but that seems really weird.

Can somebody confirm if the site keys are always 24 characters? Should I force that through my user experience?
