AroCrypt is a next-gen, cross-platform encryption toolkit built to keep your data locked down with zero friction. Encrypt text, files, and even images using strong, battle-tested cryptography. The interface stays clean, fast, and developer-friendly while the security stays airtight. Whether you're protecting personal notes or building secure workflows, AroCrypt delivers serious protection without the complexity.

• Text Encryption and Decryption
  Secure plain text using strong AES encryption with safe shareable output.

• File Encryption and Decryption
  Encrypt or decrypt any file format with reliable AES encryption. Outputs .arocrypt secure containers.

• Image Steganography
  Hide files inside .png images with automatic encryption. Only the correct private key can extract the content.

• Cross-Platform Builds

  • Windows (x64 and x32): .exe Setup and Portable
  • Linux (x64): .AppImage and .deb
  • macOS 12+ (x64 and arm64): .dmg

• Modern UI
  Clean, responsive design built for fast workflows.

• Portable Options
  No installation needed for Windows Portable or .AppImage. Just run and go.

• KEM-based Key Exchange
  AroCrypt includes Key Encapsulation Mechanisms for safer, modern key handling without exposing sensitive data.

• Improved Encryption Engine
  Faster performance, simplified data packaging, cleaner metadata handling, and upgraded security flows.

1. Enter your text.
2. Click Encrypt.
3. Copy the Base64 Data Package containing public, non-sensitive data.

1. Paste the Base64 Data Package.
2. Click Decrypt to reveal the original message.

1. Select the file or files.
2. Click Encrypt File(s).
3. A .arocrypt file will be generated.

1. Select a .arocrypt file.
2. Click Decrypt File(s).
3. Your original file or files will be restored.

1. Pick a .png container image.
2. Select the files you want to hide.
3. Click Embed File(s).
4. A new .png with encrypted embedded data will be created.

1. Select the modified .png image.
2. Click Extract File(s).
3. You will receive the encrypted embedded files. A decryption key is still required to unlock them.

AroCrypt uses industry-standard algorithms:

• AES-GCM

  • AES-256-GCM
  • AES-192-GCM
  • AES-128-GCM

• AES-CBC

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

• AES-CTR

  • AES-256-CTR
  • AES-192-CTR
  • AES-128-CTR

Includes key and IV randomization and HMAC-based integrity checks. GCM uses its own authentication tag to prevent tampering.

Your encryption keys are never uploaded, logged, or stored anywhere.

• Built with Electron.js, powered by Node.js and React.js.
• Written entirely in TypeScript.
• Encryption logic is fully custom using native Node.js crypto APIs.
• Cross-platform architecture for Windows, Linux, and macOS.

macOS will warn you when opening apps not signed with an Apple Developer ID.

1. Download the .dmg.
2. Open the app once and wait for the warning.
3. Go to System Preferences > Security and Privacy > General.
4. Click Open Anyway.
5. Confirm the prompt.

You can also right-click the app and select Open to unlock it.

• Apple Developer ID certificates cost around 99 dollars per year.
• AroCrypt is free and open source.
