Croc

Croc is a command-line utility for sending files and folders between computers using end-to-end encrypted peer-to-peer connections. It employs elliptic curve encryption and key agreement to secure data transmission between remote endpoints.

The tool allows users to coordinate transfers using a shared code phrase and supports the operation of custom relay servers to facilitate connections without relying on public infrastructure. It also includes a proxy client to route encrypted traffic through SOCKS5 proxies.

Additional capabilities include resumable data transmission for unstable connections, content filtering to exclude specific files or folders, and stream-based data piping for integration with shell pipelines via standard input and output.

4,628View on GitHub
Ockam is a zero-trust networking framework designed to secure data transit between distributed applications using an identity-based network overlay. It provides the primitives necessary to establish mutually authenticated and end-to-end encrypted connections, removing the reliance on traditional network-layer security. The project is distinguished by its use of attribute-based access control and verifiable credentials to manage trust at scale. It implements cryptographic identity rotation to maintain identity continuity and integrates with hardware-backed key management systems to secure priv

Magic-wormhole is a peer-to-peer file transfer tool used to send files, directories, and text strings between computers. It functions as a secure data relay that establishes ephemeral encrypted network tunnels for ad hoc data exchange without requiring permanent accounts or shared folders. The system utilizes a password-authenticated key exchange to establish a shared secret from a short, human-readable code. This single-use secret handshake ensures the connection is invalidated after a successful pair to prevent replay attacks, while a rendezvous server helps peers exchange connection detail

Piknik is an encrypted clipboard relay and multiplexer that coordinates the sharing of text, binary data, and shell content across multiple network hosts. It utilizes a centralized relay architecture to manage secure client connections, providing an end-to-end encrypted system for synchronizing session state and data streams. The project distinguishes itself through the use of multi-stage key derivation and API key access control to secure remote shell access. It employs end-to-end encryption and digital signatures to protect relayed content, ensuring that data is encrypted at the source befo

Send is an end-to-end encrypted file sharing service that encrypts files on the sender's device before upload, ensuring the server never sees plaintext content. It generates secure download links that are designed for single use, automatically removing access after the first successful download, and associates each share with a time-limited access token that expires after a set duration. The service operates without requiring user accounts, lowering friction for ephemeral sharing, and uses cryptographic key derivation to generate decryption keys from the download URL, eliminating server-side
