Transfer files securely between devices using acoustic transmission. Flexible encryption: send unencrypted for speed, or use AES-256/RSA. Also works as standalone encryption/decryption tool. No internet, no cables, no network required.
Choose your security level: no encryption for speed, AES-256 for symmetric encryption, or RSA for asymmetric key-based encryption.
Transfer files between devices using only sound waves. No network connection, no physical contact required.
Works completely offline. No internet required, no cloud services, no data collection. Your data stays yours.
Use SonarLink as a file encryption/decryption utility without transmission. Perfect for preparing files before transfer.
Perfect for transferring data between isolated systems without compromising security perimeters.
Select any file you want to transfer - text, keys, configurations, or documents.
Select your security level: no encryption, AES-256 symmetric, or RSA asymmetric encryption.
Your encrypted file is transmitted via sound waves between devices.
Receive the encrypted file on the target device, then decrypt it using the tool with your password or private key.
Transfer sensitive credentials and configurations between air-gapped systems without physical media.
Share code snippets, API keys, and deployment secrets securely across environments.
