Project history and usage
ccrypt is Peter Selinger's file and stream encryption utility based on the Rijndael block cipher, the cipher family selected for AES. It packages encryption, decryption, key changes, and terminal-friendly helpers into the ccrypt, ccencrypt, ccdecrypt, ccat, and ccguess commands.
Project history
The official site identifies ccrypt as software by Peter Selinger, with copyright years 2000-2018. Its documentation emphasizes Unix-style operation on files and streams, a gzip-like interface, and aliases for common modes.
The project reached release 1.9 in 2009 with portability fixes for systems including Mac OS X, Ubuntu, FreeBSD, and Solaris 10. Release 1.10 in 2012 added libccrypt.a and ccguess, and release 1.11 in 2018 updated portability, bugs, Emacs 26 compatibility, and translations.
Adoption history
The official download page lists source distributions, binaries for several operating systems, Debian packages, Redhat RPMs, Solaris packages, and OS/2 packages. The input package facts also show Homebrew, Debian, MacPorts, Nix, and Ubuntu packaging.
How it is used
ccrypt encrypts and decrypts files in place by default, adding or removing the .cpt suffix. It can also work as a filter, decrypt directly to stdout with ccat, change keys, use key files, recurse over directories, and provide Emacs integration through ps-ccrypt.
Why package nerds care
ccrypt is historically interesting as a small AES-era replacement for older Unix crypt workflows. Package maintainers care about it because it is portable C software with many CLI entry points, old platform support, and security-sensitive defaults around key prompting and in-place file updates.
