I had encrypted a folder using ES File explorer. Then later on, I upgraded my ROM from cm12 to cm13. And then, I was not able to decrypt the data with ES file explorer, after the OS update.
I know the key used for encryption. Is it possible to decrypt the data manually?
I thought it was not possible, but then i saw this post How to decrypt Adopted Storage? And now i believe there is a solution for my problem too.
