Hash Generator (MD5, SHA-1, SHA-256)

What are these hashes used for

Hash functions turn any input into a fixed-length fingerprint. Developers use them to verify file integrity, compare data without storing the original, and generate cache keys or checksums. SHA-256 is the standard today; MD5 and SHA-1 are considered cryptographically broken and should not be used to protect passwords or sensitive data.

Computed entirely in your browser

SHA hashes are generated with the browser's native crypto.subtle API, and MD5 runs through a small local implementation. Your text is never sent to a server.

Frequently asked questions

Is MD5 safe to use?

No. MD5 has known collision vulnerabilities and should only be used for non-security purposes, like quick checksums, not for hashing passwords.

Which algorithm should I use for passwords?

None of the hashes here are appropriate for password storage; use a dedicated password-hashing algorithm like bcrypt, scrypt or Argon2 with a proper salt.

Can I hash a file, not just text?

This tool currently hashes text input only.
