HEXSecure Beta description

WARNING! The file encryption is beta stage yet, so it is under development. We hope, that it will soon be ready, but you can test it if you want (please use small files, the decryption of bigger files can take really much time! <5MB). In the next versions, the algorithm may change, which will result in the disability to decrypt older files.
====================
This application is designed to encrypt smaller files or simple text. It is the improvement of the old app TXTEncrypt, with slightly better algorithms, and more user-friendly and modern interface. This app uses non-standard, closed-source algorithms, which makes it perfectly suitable for encrypting sensitive data. Though the strength of these algorithms is not officially tested, they seem to be quite strong.
You can choose between 5 algorithms, which have similar bases. The strongest one is "Threedog2", which is also used for the encryption of the files. A pro version is available from now, it disables the ads, and enables the encryption of larger files (>2 MB)
(A future feature may be a safe password storage.)
====================
Usage:
If you encrypt a text, the result will be copied to the clipboard of your device, which means, that you have to go to the desired place, (for example open the SMS application) and paste the text.
If you decrypt a text, paste it to the text-field, or write there manually, and enter the correct key, then press the decrypt button.
If you encrypt or decrypt a file, first, press the file chooser button. In the opened window, navigate to the file, which you'd like to en/decrypt, and click on it. Automatically, the file will be saved to the same place with the same name, but a ".encrypted" extension will be added. If the output file already exists, check the overwrite box, to replace it with the new one. In the non-beta versions, only a paid version will include file en-/decryption!
The android.permission.INTERNET will be used by the ads.
