Cryptographic hashing is essential for data integrity verification, password security, and file authentication. Our hash generator supports multiple algorithms (MD5, SHA-1, SHA-256, SHA-512) and processes data entirely in your browser, ensuring your sensitive information never touches external servers.
🔐 Multiple algorithms - MD5, SHA-1, SHA-256, SHA-512, and more
⚡ Instant hashing - Generate hashes in milliseconds
📁 File & text support - Hash both text input and uploaded files
🔒 100% private - All hashing happens locally in your browser
📋 Quick copy - One-click hash copying for immediate use
✅ Integrity verification - Compare hashes to verify file authenticity
Choose Secure Algorithms
Use SHA-256 or SHA-512 for security-critical applications. Avoid MD5 and SHA-1 for security purposes—they're only suitable for checksums and non-security use cases due to known vulnerabilities.
Verify File Downloads
Compare file hashes after downloading to ensure integrity. Many software providers publish SHA-256 hashes alongside downloads. Match them to verify the file hasn't been tampered with.
Never Hash Passwords Directly
For password storage, use specialized algorithms like bcrypt, Argon2, or PBKDF2 with salt. Simple SHA-256 is vulnerable to rainbow table attacks. This tool is for learning and checksums only.
Document Hash Verification
Hash important documents and store the hash separately for future verification. This proves document integrity and can serve as evidence that content hasn't been altered.
Batch File Verification
Generate hashes for multiple files to create a verification manifest. This is useful for software releases, backup verification, and ensuring dataset integrity in scientific research.
UUID Generator
Generate unique identifiers (UUID v4) for your applications.
