Piknik

Piknik is a secure network-based clipboard tool that allows users to copy and paste data seamlessly across different machines, even when they are on separate networks or behind firewalls. It enables the transfer of virtually any type of data, including text, files, and binary streams, through a staging server that relays encrypted content between clients. The system is designed with strong end-to-end encryption and signing, ensuring that intermediaries cannot access or modify the transmitted data. Piknik operates using simple command-line interactions, allowing users to push or pull data through standard input and output streams, making it highly scriptable and automation-friendly. It also supports real-time streaming, enabling multiple receivers to consume data simultaneously from a single sender. The tool is cross-platform and works across Linux, macOS, and Windows, making it versatile for development, DevOps, and secure data transfer workflows.
