Hi there, ;D
I have recently tried to encrypt my WordPress plugin and I must say it worked as described. I had the issue of hackers always getting through this Quiz plugin because of the forms that it used and this exposed me to a lot of injections where they modify my code and crash my client's site. I had to restore backup up to 5/10 times a day and this freaked me out couldn't lose my client of 8 years.
I came across this website and it decided I want to try it because I used so many other encryptions and it never worked. I later discovered that all of them are using methods and code that are readable and easy to figure out and are already out there. But since I used CipherDefence I noticed my code was completely changed I even tried using Open Ai to try and decrypt the code but it could not. I am glad I finally found a solution that actually works.
Now the actual part I want to get to is that I noticed 1 particular problem.
I followed the instruction to the teeth, I swear, after the encryption I noticed that WordPress sends me 1/2 mails a day reporting that there was a fatal crash on the plugin that I encrypted but when I checked by visiting the site, it was perfectly fine. I could not find any problem whatsoever it's really strange though. I double checked to see if there is any readability issues by updating the plugin and it updated the plugin perfectly fine without crashing anything neither was there any corrupt files detected also it reverted my code back to the original and I had to encrypt it again.
The reason I am mentioning this it does not happen everyday where I get notified about the fatal error through mail as long as the site is up and running and there are no issues for us its perfectly fine. Just trying to figure out why I am getting this error every time if this is temporary or if there is a fix for it or something.
Thank you for your valuable feedback. I have updated the script. Please re-encode your plugin and let me know
