Encryption key not decrypting form issue

Hi,

A few days ago (Friday 20th jan 2017) while testing an encrypted form the encryption key suddenly stopped decrypting the form, I generated a new key and re-submitted the form and it still didnt decrypt the submission, I tried this a few times with no success, today however (Tues 24th Jan 2017) I regenerated a new key again, resubmitted the form and it all seems to work correctly, what would be the reason behind this? had I generated too many keys maybe? or was there something "down" on Friday. This is a bit worrying as the forms in question are of a very sensitive nature and if the keys stop working at random it could be catastrophic.

any advice would be much appreciated

thanks in advance

As far as I know we did not experience any issue with the encryption feature, this may be an isolated temporary glitch that did not allow you to use your de-crypt keys. 

Please, do note that when you generate a new de-crypt key it will remove the previous one from the form, which means that the previous encrypted data will not de-crypt with the new generated key. 

Having multiple keys is not bad, in fact, it is recommended to have one key per form, but it's not recommended to generate more than one key per form due to the explained above. 

What I would suggest you is to first check this guide about encryption: Encrypted-Forms-and-How-to-Use-Them

And also let  us know if you experience the issue again, we will be glad to check the issue for you and report it to our developers. 

Thanks for your response Kevin, I'll keep an eye on the situation
