Disable Encryption

[LinAdmin2]

I've searched the forums, but can't find an answer. When I first activated my Pine Phone, I selected full disk encryption to see how it behaved. Now, after deciding that it was a mistake, and getting tired of having to enter my password so much, I want to get rid of it. However, I can't find any instructions on how to do that.

Can anyone point me to instructions on how to start over from scratch? I'm looking for a factory reset.

I also was bored to enter that long password so many times and therefore executed from remote ssh as root: cryptsetup luksAddKey. 
The system then first prompts for the original password and then I added a 3 character long password for convenience use.

Whenever confidentiality should become important, that additional key can be deleted by using: cryptsetup luksRemoveKey.
