## breaking Changes
> \[!CAUTION]
> Please be aware of breaking changes
| Version | status | Comment |
| ------- | --------------------------------------- | ------------------------------------------------------------------ |
| v0.1.0 | **NOT** compatible to higher versions. | initial creation, text mode |
| v1.0.0 | **NOT** compatible with lower versions. | optimized input/output, text mode limited to some text-based files |
| v2.0.0 | **NOT** compatible with lower versions. | binary-mode, works on every readable file. No filesize limit. |
# Documentation
> \[!TIP]
> _see also_ [Screenshots](#screenshots)
## Encryption
- 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 `.aes`
> \[!WARNING]
> don't loose your password. Decryption/Recovery without valid password is impossible!
## Decryption
- 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 ``)
## Test / Performance
**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
- fallocate -l 1G test.img
**read / write binary mode of 1 GB file with a chunk size of 4 MB**
| type | val |
| ---- | --------- |
| real | 5m52,734s |
| user | 5m49,905s |
| sys | 0m2,391s |
**read / write binary mode of 1 GB file with a chunk size of 16 MB**
| type | val |
| ---- | --------- |
| real | 5m50,753s |
| user | 5m48,691s |
| sys | 0m2,049s |
> \[!NOTE]
> so compiled chunk size is 4 MB to give better feedback about the process status.

# Installation
## Linux
Several installation packages are available, depending on your Linux system (deb, rpm, zip, AppImage).
> \[!Note]
> see (latest) Release for packages
## MacOS
- make DiskImage executable (eg. `chmod 755 file_encryption-decryption.dmg`)
- execute / double-click on the `.dmg` file. 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.
## Windows
### Set-Up
- doubleclick `setup__file_encryption-decryption__x86_amd64_v.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"
### Set-Up - De-Installation
For de-installation, go to Windows `Settings -> Apps -> installed Apps` and choose within the hamburger menu "deinstallation"
### without set-up
- unzip `file_encryption-decryption__x86_amd64_v.zip` (eg.: `file_encryption-decryption__x86_amd64_v1.1.0.zip`) to a folder
- execute/doubleclick the executable `file_encryption-decryption_x86_amd64.exe`
