FAQ — Hash Tool Free Online 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.
