    xxHash

    xxHash

    Extremely fast non-cryptographic hash algorithm

    xxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. It successfully completes the SMHasher test suite which evaluates collision, dispersion and randomness qualities of hash functions. Code is highly portable, and hashes are identical across all platforms (little / big endian). Performance on large data is only one part of the picture. Hashing is also very useful in constructions like hash tables and bloom filters. In these use cases, it's frequent to hash a lot of small data (starting at a few bytes). Algorithm's performance can be very different for such scenarios, since parts of the algorithm, such as initialization or finalization, become fixed cost. The impact of branch misprediction also becomes much more present.

    v1pad

    One-time-pad encryption using a virtual pad

    v1pad is a command-line tool that encrypts and decrypts files using one-time-pad encryption. v1pad uses a virtual pad, meaning that the one-time pad is generated dynamically based on user input instead of being stored in a file. The name v1pad is an abbreviation for Virtual One-Time Pad.

    FinalCrypt - Unbreakable One-Time Pad Encryption

    Why FinalCrypt? 1. Most people choose Disk-Encryption as it's easier to unlock a whole drive, but Big-Brother or Malware can then also read all your files. Only use File-Encryption! 2. Most software uses recently broken AES encryption. 3. Soon The Shor's algorithm will instantly break all assymmetric encryption with Quantum Computers. 4. FinalCrypt uses Symmetric One Time Pad Encryption, which is the most unbreakable encryption there is. 5. FinalCrypt is the only "One Time Pad", OpenSource, Cross-Platform, (Bulk) File Encryption Software available.

    NTK Ultra-Compression

    NTK Ultra-Compression

    Logiciel de compression de fichiers maximal indépendant du temps.

    Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

    file digest

    A command-line utility for calculating and verifying file checksums.

    Digest is a command-line utility which can be used to calculate and verify checksums of any files, similar to md5sum or RHash, but using modern hash algorithms. Supported algorithms: BLAKE, BLAKE2, Grøstl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, Skein, SM3, Streebog, Whirlpool. Usage: digest [-c] <algorithm> <filename(s)> For example, if you want to calculate the checksums using skein512/256 algorithm, use this command: digest skein512/256 * > checksums.skein To verify the checksums: digest -c skein512/256 checksums.skein You can get a full list of supported algorithms and test the performance of different algorithms on your PC using the command: digest test <iterations> <filename> This will calculate hash sum of <filename> multiple times (number of times is specified by <iterations>) and output the results with precise timings. Note: if you have a 64-bit operating system, use 64-bit binary of the utility, because it is significantly faster for large files.
