All hashing runs locally — your input never leaves the browser. MD5 and SHA-1 are unsafe for security; use SHA-256 or stronger for cryptographic needs.
How it works
- 1Type or paste text.
- 2Every hash is computed live.
- 3Copy a single hash with one click.
Use cases
- Generate cache-busting keys.
- Verify file integrity by comparing hashes.
- Produce content-addressable IDs for small strings.
Frequently asked questions
Are MD5 and SHA-1 safe for passwords?
No. Both are cryptographically broken for security use. Use SHA-256 or stronger for any security-sensitive purpose, and prefer purpose-built password hashing (bcrypt, argon2).
Where does the hashing happen?
Entirely in your browser. SHA-1/256/384/512 use the Web Crypto API; MD5 uses a small embedded pure-JS implementation.
Can I hash a file?
Not yet. File hashing is on the roadmap.

How to use MD5, SHA-1, and SHA-256 without getting fooled
What hashes are for, why MD5 and SHA-1 are still useful (just not for security), and the three cases where SHA-256 is the right answer.
