💡 How to Use

🔏 Encrypting Text

2. Click Encrypt.
3. Copy the result — it's a Base64-encoded string containing only the public keys, safe to share.

🔓 Decrypting Text

1. Paste the Base64 public key string.
2. Click Decrypt to reveal the original message.

📁 Encrypting Files

1. Select the file(s) you want to encrypt.

🖼️ Embedding Files into PNG (Steganography)

1. Select a .png image (used as a container).
2. Upload the file(s) you want to hide.
3. Click Embed File(s).
4. You’ll get a .png image that secretly contains your encrypted data.

🧩 Extracting Files from PNG

1. Select the .png image that has embedded data.
2. Click Extract File(s).

🛡️ Security

AroCrypt uses industry-standard encryption algorithms such as:

• AES-256-CBC
• AES-192-CBC
• AES-128-CBC

With key/IV randomization and optional HMAC protection for integrity. We’re committed to expanding our supported algorithms in future releases. Your encryption keys are never uploaded or stored.

🧪 Dev Notes

• Built with Electron.js, powered by Node.js and React.js.
• Entirely written in TypeScript for type safety and maintainability.
• Encryption logic is fully custom, using Node.js crypto APIs — no third-party libraries for core encryption.
• Portable architecture: runs on Windows, Linux and macOS.

🛠️ How to Install on macOS (Unsigned App Warning)

Since this app isn’t signed with an official Apple Developer ID, macOS will warn you during installation or launch.

To install and run the app:

1. Download the .dmg file.
2. Open the app — macOS will block it and show a warning like: “App can’t be opened because it is from an unidentified developer.”
3. To bypass this:

• Open System Preferences > Security & Privacy > General tab.
• You’ll see a message about the blocked app with an “Open Anyway” button. Click it.
• Confirm when prompted.

4. Alternatively, you can right-click (or Control + click) the app and choose Open, then confirm the warning.

> [!CAUTION] > This warning is a macOS security feature to protect your system. Only bypass if you trust the source.

Why no official signing?

• Official Apple Developer ID certificates cost money (~$99/year).
• This app is free and open source, so we rely on you to verify and trust the app yourself.

For future updates

Check GitHub releases or the official website to download new versions manually.
