Encryption Manager на Android

Разработчик приложения Encryption Manager: giraone

Encryption Manager is a file manager, that offers a comfortable and secure way to keep files with confidential data encrypted on the internal or external SD card.

Keywords: file encryption, data encryption, file manager, crypto, SD card, encryption algorithm, AES, Twofish

A master password is both used to access the application and to encrypt the encryption keys, that are generated random for each file, that is managed by Encryption Manager. Confidential files are accessible directly after the login. With one click on the file, the file is decrypted to its original location and can be shown by the installed viewer or editor apps. When you are finished working with the decrypted copy, the file is re-encrypted with one click and the decrypted file is wiped from the SD card. This wipe process will overwrite the data with random bytes before the file is deleted. So even if the device is lost or stolen, it is not possible to access your confidential data.

Encrypting new files is very simple: they can be chosen with the built-in file manager or by using "send/share" from another app.
