- choose a file to encrypt
- activate the checkbox to encrypt the source file (original file will be replaced with the encrypted one)
- keep checkbox unchecked to encrypt the given file into a new (encrypted) file.
- encrypted file will be stored as
<filename>.aes
Warning
don't loose your password. Decryption/Recovery without valid password is impossible!
- choose a file to decrypt (only files with extension ".aes")
- activate the checkbox to decrypt the source file (original file will be replaced with the decrypted one)
- keep checkbox unchecked to decrypt the given file into a new (decrypted) file.
- decrypted file will be stored as
<originalfilename>)
tested on
- x86_64 Ubuntu 24.04.2 LTS
- Intel(R) Core(TM) i5-9600K CPU @ 3.70GHz with 6 cpu cores
- average SSD storage

Several installation packages are available, depending on your Linux system (deb, rpm, zip, AppImage).
Note
see (latest) Release for packages
- make DiskImage executable (eg.
chmod 755 file_encryption-decryption.dmg) - execute / double-click on the
.dmgfile. A window should appear showing the program you are installing and the Applications Folder. - drag the program into the Applications Folder; macOS will automatically install the software for you.
- doubleclick
setup__file_encryption-decryption__x86_amd64_v<VERSION>.exe(eg.:setup__file_encryption-decryption__x86_amd64_v1.1.0.exe) - choose "install for all users" (Administrator rights needed)
- choose "install for current user only" (no Administrator rights needed)
- choose "select language (DE|EN) to use during installation"
For de-installation, go to Windows Settings -> Apps -> installed Apps and choose within the hamburger menu "deinstallation"
- unzip
file_encryption-decryption__x86_amd64_v<VERSION>.zip(eg.:file_encryption-decryption__x86_amd64_v1.1.0.zip) to a folder - execute/doubleclick the executable
file_encryption-decryption_x86_amd64.exe
