Why Use Free Online Hash Generator?
Five Algorithms
Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes all at once. Compare or choose the one you need.
File Hashing
Hash any file type to verify integrity or create checksums. Perfect for verifying downloads or detecting file changes.
100% Private
All hashing uses the Web Crypto API in your browser. Your data and files never leave your device.
Instant Results
Hash generation is fast even for large files. Results appear immediately with one-click copy functionality.
Common Uses for Hash Generator
File Verification
Verify downloaded files match their published checksums to ensure integrity.
Password Hashing
Understand how password hashing works for secure storage in databases.
Data Integrity
Create checksums to detect file corruption or unauthorized modifications.
Development & Testing
Generate hashes for API authentication, caching keys, and testing purposes.
How It Works
Choose Input Type
Select "Text Input" to hash a string, or "File Input" to generate hashes for any file like documents, images, or executables.
Enter or Upload Data
Type or paste your text, or click the upload area to select a file. The tool processes data of any size directly in your browser.
Copy Your Hashes
All five hash algorithms generate simultaneously. Click the copy button next to any hash to copy it to your clipboard instantly.
Hashing Best Practices
Use SHA-256 for Security
For any security-sensitive application (passwords, signatures, integrity checks), always use SHA-256 or SHA-512. Avoid MD5 and SHA-1.
Verify Downloads
Always compare the hash of downloaded software with the publisher's checksum to ensure the file hasn't been tampered with.
MD5 is Broken
MD5 has known collision vulnerabilities. Never use it for security purposes. It's included here only for legacy compatibility.
