    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer...

    LZ4

    LZ4

    Extremely fast compression algorithm

    LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's...

    Reliable PostgreSQL Backup & Restore

    Reliable PostgreSQL Backup & Restore

    Reliable PostgreSQL backup and restore

    pgBackRest aims to be a reliable, easy-to-use backup and restore solution that can seamlessly scale up to the largest databases and workloads by utilizing algorithms that are optimized for database-specific requirements. Compression is usually the bottleneck during backup operations but, even with now-ubiquitous multi-core servers, most database backup solutions are still single-process. pgBackRest solves the compression bottleneck with parallel processing. Utilizing multiple cores for...

    LibSecRm - Secure Removal Library

    LibSecRm - Secure Removal Library

    A library for secure deleting data on-the-fly

    LibSecRm (LIBrary for SECure ReMoval) is a set of replacements for these standard C functions which cause data removing from files. The data is first securely wiped on-the-fly, to protect the user's privacy, then the original functions are called. There is NO NEED to rebuild your software, because LibSecRm is a pre-loadable library, meaning you just need to RUN the software with LibSecRm loaded. LibSecRm is also a development library. The following wiping methods are supported:...

    FreeOTFE

    FreeOTFE

    A free "on-the-fly" transparent disk encryption program for PC & PDAs.

    An upstream source site housing the original files for this mirror is no longer available. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.

    Firefly's Clean Lzo

    A human-readable ISC-Licensed implementation of the LZO1X algorithm.

    LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In...
