What program can encrypt / password files on Android?

Question

Android

Can you tell me a decent software for Androd that can encrypt and spill data on Android?
That is, it is not a super crypter that is of interest, but rather to protect against a simple shkolota, so that you can quickly use the file when entering a password.
And, well, files need to be encrypted / password-protected on a memory card (like my ES Explorer for some reason does not know how to do this) ...
