I'm looking for a lightweight Android app, that:
- lets the user choose a file
- asks for the password
- opens this file and displays the decrypted content in a textarea (scrollable)
However, the app:
should not write the decrypted file on disk (internal or external microSD card) but only displays it,
it should not require network access at all.
the app should use a standardized AES encryption (the input file will be encrypted on PC / Windows, and it has to be read on the phone).
the app should be able to deal with > 300 kB files (so it seems that opening a file in a text editor, Select All, Copy, go in encrypt/decrypt app, Paste won't work, because I noticed that clipboard doesn't seem to support Copy/paste with > 300 kB files).
Also I've looked at this list of apps, and none of them really meets all these criteria.
I'm pretty sure it will be difficult to find an app that meets all criteria, so if there is an open-source app that does most of them, I'll be happy to fork it.
Application: Sometimes I have a big text file (written on PC / Windows), and I'd like to read it (read-only) on my phone.
