Seltsamerweise kann ich keine portable Anwendung finden, um einen bestimmten Hash (Typ wie SHA256, SHA512, Whirlpool, SHA3?) Für eine ausgewählte Datei zu berechnen! Das ist alles, was ich gefunden habe:
Es gibt Multihasher , aber es unterstützt einige wichtige Hash-Typen wie SHA-3 und Whirlpool nicht.
HashTab hat alles, was ich brauche, aber ... schade! Es ist eine installierbare DLL für die Systemintegration ohne portable Anwendung.
Eigentlich bin ich etwas geschockt von dieser Situation. Ich hätte nie erwartet, dass ich nicht in der Lage sein würde, die geeignete Software für ein so häufiges Problem zu finden.
Vor einiger Zeit habe ich ein kleines Befehlszeilenprogramm für mich erstellt. Laden Sie es herunter, wenn Sie es nützlich finden.
Das Programm wurde noch nie zuvor veröffentlicht (oder signiert), sodass es möglicherweise als Malware erkannt wird (zumindest sagt VirusTotal das).
Es ist in Python 3 geschrieben. Dies ist die Quelle:

Es kann eine Datei oder einen Ordner mit diesen Algorithmen hashen:
md4
md5
sha3_512
Sie können die gehashten Werte auch in einer Datei speichern oder sie zum einfachen Analysieren mit json formatieren.
Das Schöne daran ist, dass Sie ganz einfach eine .bat-Datei erstellen können, um sie zu automatisieren.
Wenn Sie dieses Programm tatsächlich brauchen, aber Ihrem Antivirus mehr vertrauen als mir, kompilieren Sie die obige Quelle mit pyinstaller .
pip install pyinstaller pyinstaller hasher.py4.5 Führen Sie optional Folgendes aus: pyinstaller hasher.py --onefilewenn Sie nur eine ausführbare Datei wünschenBeachten Sie, dass die Kompatibilität der kompilierten Exe nicht getestet wurde, da ich keine Zeit habe.
rhash ist ein cmdline-Tool, das einzelne Hashes berechnen kann.
Sie können mein Shellex.bat-Skript verwenden , um einen Eintrag im Kontextmenü des Explorers hinzuzufügen, der den Hash in einem Konsolenfenster anzeigt.
Beispielsweise wird dadurch jeder Datei ein „CRC32“-Befehl hinzugefügt (einfügen und aus einer Batch-Datei ausführen):
call shellex * CRC32 ""%~d0\PortableApps\ConEmu\ConEmu.exe" /cmd "%PROGRAMFILES%\Rhash\rhash.exe" -C --simple ""%%%%1"""
Eine weitere Option mit Certuil ist hier .
Übrigens, für kleine Dateien bevorzuge ich eigentlich HashMyFiles wegen der benutzerfreundlicheren GUI.
