Cdrkit is a suite of programs for recording CDs and DVDs, blanking CD-RW media, creating ISO-9660 file system images, extracting audio CD data, and more. It's mostly compatible with cdrtools.

Optical media (CD,DVD,BD) keep their data only for a finite time (typically for many years). After that time, data loss develops slowly with read errors growing from the outer media region towards the inside.

Dvdisaster stores data on CD/DVD/BD (supported media) in a way that it is fully recoverable even after some read errors have developed. This enables you to rescue the complete data to a new medium.

Data loss is prevented by using error correcting codes. Error correction data is either added to the medium or kept in separate error correction files. Dvdisaster works at the image level so that the recovery does not depend on the file system of the medium. The maximum error correction capacity is user-selectable.

cdrtools is a collection of command line utilities to create CD's, DVD's or Blue Ray discs. The most important components are cdrecord, a burning program, cdda2wav, a CD audio ripper which uses libparanoia, and mkisofs, which can create various disc images.

Cdparanoia retrieves audio tracks from CDDA capable CDROM drives. The data can be saved to a file or directed to standard output in WAV, AIFF, AIFF-C or raw format. Most ATAPI, SCSI and several proprietary CDROM drive makes are supported; cdparanoia can determine if the target drive is CDDA capable. In addition to simple reading, cdparanoia adds extra-robust data verification, synchronization, error handling and scratch reconstruction capability.

The GNU Compact Disc Input and Control Library (libcdio) is a library for CD-ROM and CD image file access. It allows the developer to add CD access to an application without having to worry about the OS- and device-dependent properties of CD-ROM or the specific details of CD image formats. It includes pycdio, a Python interface to libcdio, and libcdio-paranoia, a library providing jitter-free and error-free audio extraction from CDs.

Asunder is a graphical audio CD ripper and encoder. It can save audio tracks as WAV, MP3, Ogg Vorbis, FLAC, Opus, Wavpack, and Musepack. It can use CDDB to name and tag each track automatically, and it allows for each track to be by a different artist. Asunder can encode to multiple formats in one session, and it can create M3U playlists.

libMirage is a CD-ROM image access library. It supports the following formats: B6T, C2D, CCD, CDI, CIF, CUE, ISO, MDS, MDX, NRG, TOC. It is written in C and based on GLib. Its aim is to provide uniform access to the data stored in various image formats.

Libisofs creates ISO 9660 (also known as ECMA-119) file system images which can either be written to POSIX file objects or handed over to libburn for being written directly to optical media. It can read metadata of ISO 9660 filesystems, manipulate them, and use them to produce new complete file system images or add-on images to be appended to the read file system image. Supported extensions to ISO 9660 are Rock Ridge, Joliet, AAIP, zisofs.

Libburn is a library for reading and writing optical discs. Supported media are: CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW, DVD-R, DVD-R/DL, BD-R, and BD-RE.

cdrdao records audio or data CDs in disk-at-once (DAO) mode, based on a textual description of the contents. This mode writes the complete disc – lead-in, one or more tracks, and lead-out – in a single step and is commonly used with audio CDs. cdrdao can also handle the bin/cue format, commonly used for VCDs or disks with subchannel data.

abcde is a front-end command-line utility (actually, a shell script) that grabs tracks off a CD, encodes them to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+ (Musepack) format, and tags them, all in one go.

GNU ccd2cue is a preprocessor for CD burning software that allows the conversion of the proprietary CCD format to the CUE format, which is well-supported by free software. These files are commonly distributed with CD images and are used to describe how tracks are laid out on the image.

libcdio-paranoia is an implementation of CD paranoia libraries based on libcdio.

The deSEC can be used to obtain certificates with certbot DNS ownership verification. With the help of this hook script, you can obtain your Let's Encrypt certificate using certbot with authorization provided by the DNS challenge mechanism, that is, you will not need a running web server or any port forwarding to your local machine.

This package provides a certificate store containing only the Let's Encrypt root and intermediate certificates. It is intended to be used within Guix.

mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration.

This is a C version of the certdata2pem Python utility that was originally contributed to Debian.

Testscenarios provides clean dependency injection for Python unittest style tests.

This package provides a Pytest plugin which enables running each test in a subprocess and will report if a test crashed the process. It can be useful to isolate tests against undesirable global environment side-effects (such as setting environment variables).

Python-subunit is a Python implementation of the subunit test streaming protocol.

The libfaketime library allows users to modify the system time that an application "sees". It is meant to be loaded using the dynamic linker's LD_PRELOAD environment variable. The faketime command provides a simple way to achieve this.

Fixtures provides a way to create reusable state, useful when writing Python tests.

CBehave is a behavior-driven development implemented in C. It allows the specification of behaviour scenarios using a given-when-then pattern.

This package provides a go test runner with output optimized for humans, JUnit XML for CI integration, and a summary of the test results.
