history

Project history and usage

croc is a cross-platform CLI for simple, encrypted file and folder transfer between two computers. It combines a relay, password-authenticated key agreement, resumable transfers, and package-manager-friendly binaries into a tool aimed at replacing ad hoc local servers, port forwarding, or manual cloud handoffs.

Project history

The project began in 2017 and later standardized around a Go module and release binaries. Its README describes the core promise as allowing any two computers to transfer data through a relay while preserving end-to-end encryption using PAKE.

Over time the feature set grew beyond one-shot file sending: multiple files, interrupted-transfer resume, IPv6-first behavior with IPv4 fallback, proxy support, text transfer, pipes, QR codes, Docker usage, and platform-specific install paths are all part of the official documentation.

Adoption history

The official install section documents Homebrew and MacPorts on macOS, Scoop, Chocolatey, and Winget on Windows, Nix and NixOS, pacman on Arch, dnf on Fedora, portage on Gentoo, Termux, FreeBSD pkg, conda-forge, Docker, and Go source builds. That breadth made croc a common package-index entry for secure peer-to-peer-ish file transfer even though the protocol uses relays.

How it is used

A sender runs croc send with files or folders and receives a code phrase; the recipient runs croc with that phrase. The phrase establishes the PAKE-derived shared secret used for end-to-end encryption, while the relay helps two machines connect without a local server or port forwarding.

Why package nerds care

croc is interesting to package maintainers because it is a network CLI where usability depends heavily on reproducible, cross-platform binary distribution. The same project appears in many package ecosystems, and its runtime behavior is intentionally simple enough to be useful from ephemeral shells, developer machines, and constrained environments.

Timeline

  • 2017: Repository created.
  • 2020: v8 release line published on GitHub releases.
  • 2020s: Official installation instructions expanded across macOS, Windows, Linux distributions, BSD, Termux, Conda, Docker, and Go.

Related projects

  • PAKE is the cryptographic primitive used to derive the transfer secret from the code phrase.
  • Package ecosystems including Homebrew, MacPorts, Scoop, Chocolatey, Winget, Nix, pacman, dnf, portage, FreeBSD pkg, Termux, and conda-forge distribute or document croc installation.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for croc. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • Homebrew bottle metadata is available for 6 platform targets.
  • Build metadata lists 1 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
