Crypt::RSA is a pure-perl, cleanroom implementation of the RSA public-key cryptosystem. It uses Math::Pari(3), a perl interface to the blazingly fast PARI library, for big integer arithmetic and number theoretic computations. Crypt::RSA provides arbitrary size key-pair generation, plaintext-aware encryption (OAEP) and digital signatures with appendix (PSS). For compatibility with SSLv3, RSAREF2, PGP and other applications that follow the PKCS #1 v1.5 standard, it also provides PKCS #1 v1.5 encryption and signatures. Crypt::RSA is structured as bundle of modules that encapsulate different parts of the RSA cryptosystem. The RSA algorithm is implemented in Crypt::RSA::Primitives(3). Encryption schemes, located under Crypt::RSA::ES, and signature schemes, located under Crypt::RSA::SS, use the RSA algorithm to build encryption/signature schemes that employ secure padding. (See the note on Security of Padding Schemes.) The key generation engine and other functions that work on both components of the key-pair are encapsulated in Crypt::RSA::Key(3). Crypt::RSA::Key::Public(3) & Crypt::RSA::Key::Private(3) provide mechanisms for storage & retrival of keys from disk, decoding & encoding of keys in certain formats, and secure representation of keys in memory. Finally, the Crypt::RSA module provides a convenient, DWIM wrapper around the rest of the modules in the bundle.

The main advantages to the Sun format utility are: - Working surface analyze that will detect defective blocks that are going to get bad. - Analyzing program that detects defective bearings in the disk (-randrw). - Will repair nearly any defective disk, that has no firmware bug or electric defect. - Allows to clear the grown defect list if a disk. - Disk geometry and label geometry are separated. - Allows cheating in the label geometry to deal with the problems with the limitation to 16 bit data types in the Sun disk label. - Large database of disks including firmware specials. - You need no desk calculator to generate a partition table. Shorthands for: - MBytes - cylinders/head/sectors - size partition to end on end of disk - partition following another partition - partition ending before another partition - shifting partition on the disk (allows growing part 0 and shrinking part 1) - Partition consistency checker with (ascii) graphical display. - Mode page interpreter allows to set easily all mode pages you will ever find in a manual, sformat needs not to know about them. NOTE: Sformat has its full functionality on SunOS/Solaris on sparc and Motorola systems, on all other systems sformat will create Sun disk labels with wrong byte-order, but formatting/analysis/ repair will work.

This is open source implementation of the world-famous ARJ archiver. This version has been created with an intent to preserve maximum compatibility and retain the feature set of the original ARJ archiver as provided by ARJ Software, Inc. New ARJ features on Unix-like platforms: - Support for symbolic and hard links - Archiving of special entities: pipes and devices - Support for UID/GID storage in a variety of methods - World's smallest native self-extracting modules - Interoperability with ARJ for DOS, Windows, and OS/2 Warp

[ excerpt from developer's web site ] JZlib is a re-implementation of zlib in pure Java. The first and final aim for hacking this stuff is to add the packet compression support to pure Java SSH systems. - Why JZlib? Java Platform API provides packages 'java.util.zip.*' for accessing to zlib, but that support is very limited if you need to use the essence of zlib. For example, we needed to full access to zlib to add the packet compression support to pure Java SSH system, but they are useless for our requirements. The Internet draft SSH Transport Layer Protocol says in the section '4.2 Compression' as follows,

LASzip is a compression library for compressing ASPRS LAS format data. It has been provided as an LGPL-licensed stand-alone software library to allow other softwares that handle LAS data to read and write LASzip-compressed data. The BSD-licensed libLAS and the LGPL-licensed LASlib can take advantage of LASzip to read and write compressed data. LASzip is completely lossless. It compresses bulky LAS files into compact LAZ files that are only 10-20 percent of the original size, accurately preserving every single bit.

gnormalize decodes the MP3/MP4/MPC/OGG/APE/FLAC file to WAV, then normalizes the WAV to a targeted volume level and re-encodes it. Moreover, gnormalize can extract Audio CD track and output as various popular audio formats (MP3, MP4, MPC, OGG, APE, FLAC, WAV) with fast speed and high quality. gnormalize can also convert audio format between MP3, MP4, MPC, OGG, APE and FLAC with high fidelity, which meets your need to play and collect audio files. It can change the encoding and Metadata (tag) properties of final normalized files.

Game_Music_Emu is a collection of video game music file emulators that support the following formats and systems: AY ZX Spectrum/Amstrad CPC GBS Nintendo Game Boy GYM Sega Genesis/Mega Drive HES NEC TurboGrafx-16/PC Engine KSS MSX Home Computer/other Z80 systems (doesn't support FM sound) NSF/NSFE Nintendo NES/Famicom (with VRC 6, Namco 106, and FME-7 sound) SAP Atari systems using POKEY sound chip SPC Super Nintendo/Super Famicom VGM/VGZ Sega Master System/Mark III, Sega Genesis/Mega Drive,BBC Micro

Tired of reaching for your volume knob every time your MP3 player changes to a new song? MP3Gain analyzes and adjusts MP3 files so that they have the same volume. MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear. Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the MP3 file directly, without decoding and re-encoding.

MikMod is a portable modules player originally written by of Jean-Paul Mikkers (MikMak) for DOS. Current MikMod'Unix maintainer (since version 3.0.4) is Miodrag Vallat <miodrag@mygale.org> It uses the OSS /dev/dsp driver including in all recent kernels for output, and will also write wav files. Supported file formats include mod, stm, s3m, mtm, xm, and it. The player uses ncurses for console output and supports transparent loading from gzip/pkzip/zoo archives and the loading/saving of playlists. Full source included, use of this library for music/sound effects in your own programs is encouraged!

Vorbis is a general-purpose audio and music encoding format contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond MPEG audio layer 3. Unlike the MPEG sponsored formats (and other proprietary formats such as RealAudio G2 and Windows' flavor of the month), the Vorbis CODEC specification belongs to the public domain. All the technical details are published and documented, and any software entity may make full use of the format without royalty or patent concerns. This package contains utilities to encode, decode, and cut vorbis streams, and to add comments to them.
