I'm looking for a way to create an encrypted folder on the sd-card and provide password protected access to its contents. Ideally, this would provide a UI to encrypt new files by moving files to it and retrieve them back.
I know there is EncFS but it only works in rooted devices. And also BoxCryptor which is only for Google Drive or DropBox.
I need a solution which would work with sd-card folders and on unrooted devices.
