AES-Encrypt-CLI

AES-Encrypt is a CLI-tool to encrypt any file you want. Simply start the program, enter the file name, your key and encrypt it using AES-256.

This tool uses the GCM (Galois/Counter Mode) because it allows messages longer than the block length of the block cipher to be encrypted.

A GUI version is likely.

‼️ Trust, but verify ‼️

THIS IS FOR EDUCATIONAL PURPOSES. DON'T RELY ON IT!!! (it works though)

Installation

Clone the repository:

  git clone https://github.com/realPJL/encrypt-file-cli.git
  cd encrypt-file-cli

Go to the cmd folder and build the app (replace theApplicationName with your desired name):

  cd cmd
  go build -o theApplicationName

Move the new application to the folder containing your secret and key file. Keep in mind that the key needs to be 32 bytes big.

---

The application, the key and the desired file need to be in the same folder when running the program.

Usage

On Windows:

  theApplicationName.exe

On macOS, Linux

  ./theApplicationName

After starting the program choose your desired mode E (Encryption) or D (Decryption). Then, please type in the name of the file you want to en-/decrypt:

  secret.md

The file will be read. After it has been read enter your key file:

  key.txt

Your encrypted file will be stored inside a new folder encryptedFiles and have the name of your original file and the prefix ENCRYPTED_ as well as a new file ending .enc.

Contributing

Feel free to contribute your desired functionality. Just fork the repo and start working. I'll probably abon this CLI version for the GUI version (it's just better UX for normal people). You can find the GUI version here: TBD
