Common Use Cases
File integrity
Verify downloaded files haven't been tampered with by comparing hashes.
Password hashing
Hash passwords with salt before storing (though bcrypt is preferred for passwords).
Git commit verification

FAQ About Hash Tool
Is MD5 secure?
No. MD5 has known collision vulnerabilities. Use SHA-256 or SHA-512 for security. MD5 is OK for non-security checksums.
What is a salt?
A random string added to a password before hashing to prevent rainbow table attacks. bcrypt includes salt automatically.
Is my data private?
Yes. All hashing happens in your browser. Nothing is uploaded.
