history
Project history and usage
reop, short for reasonable expectation of privacy, is a minimalist command-line tool for signatures and file encryption.
Project history
The README frames reop as an extension of ideas from signify rather than an OpenPGP clone. It was written by Ted Unangst and uses NaCl/libsodium primitives for signing and encryption.
Adoption history
reop was adopted mainly by BSD and Homebrew-style packaging channels as a compact alternative to larger tools such as GnuPG or OpenSSL for simple signing and encryption workflows. Homebrew packages version 2.1.1 from a ports distfile and marks it unmaintained.
How it is used
The manual documents modes for generating keys, encrypting, decrypting, signing, and verifying. It searches ~/.reop for default key files named seckey, pubkey, and pubkeyring, while command-line options can point to explicit key and message files.
Why package nerds care
reop is notable to package maintainers because it is a small cryptographic CLI with a tight dependency story around libsodium, explicit limits, a simple trust model, and source releases that remain useful even without broad ecosystem adoption.
Timeline
