About This Tool

What is Hash-Generator?

A tool for generating hash values from text. Supports major hash algorithms including MD5, SHA-1, SHA-256, and SHA-512. Used for file integrity verification, password hashing, and data checksum validation.

How to Use

  1. Select a hash algorithm (MD5, SHA-1, SHA-256, SHA-512).
  2. Enter the text to hash in the input area.
  3. The hash value is automatically generated.
  4. Copy the result for your use.

Key Features

  • Supports MD5, SHA-1, SHA-256, SHA-512 algorithms
  • Automatic hash calculation on input
  • One-click result copying
  • Uses browser's built-in Web Crypto API

Tips

  • SHA-256 is the most widely used secure hash algorithm today.
  • MD5 and SHA-1 are not recommended for security purposes but still useful for checksums.
  • The same input always produces the same hash value, making it ideal for data integrity verification.

Frequently Asked Questions

Warum MD5/SHA-1 unsicher?

Bekannte Kollisionsschwachstellen. MD5-Kollisionen in Sekunden erzeugbar. SHA-256+ für Sicherheit verwenden.

Hash umkehren?

Nein — Einwegfunktion. Häufige Passwörter via Rainbow-Tabellen findbar, daher mit Salt hashen.

Hashing vs Verschlüsselung?

Hashing: einweg, fester Digest. Verschlüsselung: bidirektional mit Schlüssel. Hashing für Integrität; Verschlüsselung für Datenwiederherstellung.
