Installation

Build

• To build the application run below command. Build files will be output to bin/Desktop directory.

npm run electron:dev

• This application is built and tested on Windows 10. Other platforms are not tested yet.

• After building the application, run the setup in bin/Desktop directory. After the installation app will automatically open.

• To directly run the app without installing, run the executable file in bin/Desktop/win-unpacked.

Usage

Initial UI.

Symmetric encryption and decryption (AES)

• A symmetric key can be generated by clicking on the Generate Key button.
• A password can be supplied, or it can be left empty to automatically generate a random password.

• After generating a key, enter your secret message into below textarea and click encrypt button.

• Upon clicking encrypt, the message will be replaced by the ciphertext.

• Copy both ciphertext and key into clipboard. Switch to decrypt mode and paste key and ciphertext into relevant fields.

• Upon clicking decrypt button, decrypted text will be displayed.

Asymmetric encryption and decryption (RSA)

• A key pair can be generated and saved in .pem format by clicking on generate key pair button. It will open a dialog to indicate save location.

• Select your desired location in the computer and pub.pem and pri.pem will be saved there. It may take a few moments to generate keys.

• Then, enter a secret message in the field and select the generated public key using select public key button in order to encrypt it. The selected key name will be displayed next to the button.

• Click the encrypt button, and the ciphertext will be displayed in the below textarea.

• Copy the ciphertext and switch to decrypt mode.

• Paste the ciphertext into the textarea and select the private key using select private key button.

• Click the decrypt button to decipher the text.

• Done!

Code quality is pretty ridiculous. Contributions are welcome.
