BLAKE3
BLAKE3 ist eine Hochleistungs-Implementierung des kryptografischen BLAKE3-Hash-Algorithmus zur Berechnung sicherer Daten-Digests und Fingerabdrücke. Es fungiert als paralleles kryptografisches Hash-Tool, das Workloads über mehrere Prozessor-Threads verteilt, um große Datensätze schnell zu verarbeiten.
Das Projekt bietet spezialisierte Tools für Keyed-Hashing und die Generierung von Message Authentication Codes. Es enthält zudem Funktionen für die kryptografische Schlüsselableitung, die die Erstellung eindeutiger geheimer Sub-Keys aus einem Master-Key und Kontext-Strings ermöglichen.
Die Implementierung unterstützt die Integritätsprüfung von Daten durch parallele Hash-Berechnung und verifiziertes Daten-Streaming. Diese Funktionen werden als sprachübergreifende Bibliothek für Rust- und C-Umgebungen bereitgestellt und enthalten eine Kommandozeilenschnittstelle zur Berechnung von Digests für Dateien oder Standard-Eingaben.
