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.

There are many available choices, depending on the features you need:

  • Cryptonite uses EncFS and requires root
  • LUKS also requires root and provides on-the-fly encryption (AES by default) to virtual folders
  • Eds provides encrypted containers and does not require root. It even is compatible to TrueCrypt.
  • DroidCrypt can encrypt single files or full directories. No root needed.
  • Encryption Manager is a file manager providing file encryption support, and so is AnDisk
  • FilesCrypter supports encrypted files and folders

And many more.¹ Just check the examples, and take a look at the "also recommended" stuff on their market pages to find more.

  • Thanks, I will buy and try Eds. It seems to have everything I needed. – Behzad Momahed Heravi Jul 11 '12 at 10:58
  • @BehzadMomahedHeravi There's also a free trial available if you want to check it first. Eds looks like the best choice to me as well, though I did not (yet) try any of those apps. Good thing about the TrueCrypt containers is, this way you can even safely store data in the cloud ;) – Izzy Jul 11 '12 at 11:43
  • Most of these links are dead. Are there new pages for these apps—were they renamed? Only EDS and Encryption Manager still have pages at the given URLs. – intuited Aug 17 '18 at 14:06
  • @intuited you've noticed that answer is 6 years old? That's half an eternity technically :) May I suggest you check with my corresponding app listing? That's kept updated. – Izzy Aug 17 '18 at 14:10
  • It might be helpful to update answers every half-eternity or so—otherwise they cease to be useful. That link to your app listing doesn't seem to work: it required a name and password. – intuited Aug 17 '18 at 14:35
  • @intuited please count the number of answers I've given here. Can't track them all. Core answers I update from time to time, but keeping track of all would be a full-time job. Apart from that: This is not app recommendations. So the apps linked are just examples. Even if the links die, the answer is still valid: There are apps for this, and their names look like that. // Included the link to my corresponding app listing, which (as I already wrote) is kept up-to-date. – Izzy Aug 17 '18 at 19:37

There's LUKS Manager which is available in the Play Store. It also requires your device to be rooted, however.

It's also open source. I have not tried it myself however, so I can't comment on how well it works.

The closes you can get without a rooted device is probably full disk encryption.
