## Projektgeschichte und Nutzung

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.

### Projektgeschichte

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.

### Adoptionsgeschichte

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.

### Wie es verwendet wird

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.

### Warum Paket-Nerds sich dafür interessieren

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.

### Zeitleiste

- 2000: Copyright period begins for ccrypt.
- 2009: Version 1.9 released with portability fixes for multiple Unix-like systems.
- 2012: Version 1.10 released with libccrypt.a and ccguess.
- 2018: Version 1.11 released with portability fixes and Emacs 26 compatibility.

### Related projects

- ps-ccrypt provides Emacs support for encrypted .cpt files.
- The official site lists GUI and integration tools such as Qccrypt and CCRYPTGUI.
