➤ Algorithms: Everything is encrypted using strong encryption algorithms: AES (Rijndael) 256bit RC6 256bit Serpent 256bit Blowfish 448bit Twofish 256bit GOST 256bit + Threefish 1024bit and SHACAL-2 512bit (for S.S.E. Pro Version) ciphers are available.
➤ Steganography: The Text Encryptor contains a steganographic feature (concealing a text within an image - JPG). A steganographic algorithm (F5 algorithm) is used in combination with chosen symmetric cipher algorithm to make a final steganogram (JPEG image).

★★★ FAQ ★★★
Issue: File Encryptor sub application - My file(s) are still visible after the encryption.
Answer: The SSE File Encryptor works as an archiver (a new .enc file is created). You can delete/wipe the original file(s) after the encryption process is completed or it can be done automatically: Settings: File Encryptor → Wipe Source After Encryption

Issue: KitKat (Android 4.4) - File Encryptor sub application - External SD Card is read only - message: EACCESS (Permission denied).
Answer: Android 4.4 does not allow write access to the external SD card to any app except for preinstalled apps (preinstalled by device or system image manufacturer). We can do absolutely nothing about this issue. The only solution is to root your device and change permissions (for example: http://technofaq.org/posts/2014/04/fixing-external-sd-card-write-issue-on-android-kitkat ) or upgrade to Android 5+ and use SAF mode.
Alternatively - Create the following directory (on your external SD card):
Android/data/com.paranoiaworks.unicus.android.sse
The app should have write permissions in this folder.
