CDSA stands for Common Data Security Architecture. It provides a security framework that includes cryptographically signed modules to present an abstracted unified API to the application developer to perform cryptographic and security related operations. It also includes hardware support for cryptographic tokens and biometric devices, such as thumbprint scanners. Intel has implemented the CDSA 2 specification and released it as open source.
cdrtools (formerly cdrecord) creates home-burned CDs/DVDs with a CDR/CDRW/DVD/BluRay recorder. It works as a burn engine for several applications. It supports CD/DVD/BD recorders from many different vendors; all SCSI-3/mmc- and ATAPI/mmc-compliant drives should also work. Supported features include IDE/ATAPI, parallel port, and SCSI drives; audio CDs, data CDs, and mixed CDs; full multi-session support; CD-RWs, DVD-R/-RW, DVD+R/+RW, BD-R/BD-RE; and TAO, DAO, RAW, and human-readable error messages. cdrtools includes remote SCSI support and can access local or remote CD/DVD/BD writers.
Cdrdao records audio/data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents (toc-file). Features include full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks. Control over sub-channel data like catalog numbers, copy, pre-emphasis, 2-/4-channel flags, ISRC code, and index marks are provided as well. GCDMaster is a Gnome GUI front-end that lets you import MP3 and WAV files, select track markers and cut/copy/paste audio snippets before burning.
CDR-Toaster is a Tk frontend for writing CDs. It is a graphical front-end for the excelent programs 'mkisofs', 'cdrecord' and 'cdparanoia'. It may be used to burn audio, data, bootable, and combo CDs. It can also rip audio and data tracks. CDR-Toaster can even burn mp3s as audio CDs.
cdparanoia reads audio from the CDROM directly as data, with no analog step between, and writes the data to a file or pipe in WAV, AIFC or raw 16 bit linear PCM. Cdparanoia will read correct, rock-solid audio data from inexpensive drives prone to misalignment, frame jitter and loss of streaming during atomic reads. cdparanoia will also read and repair data from CDs that have been damaged in some way.
