Type or paste any text and get MD5, SHA-1, SHA-256, and SHA-512 hex digests, updating live with every keystroke. SHA-1, SHA-256, and SHA-512 run through the browser's native Web Crypto SubtleCrypto API — the same engine used for TLS and WebAuthn — so results match any standard implementation exactly. Web Crypto deliberately doesn't include MD5 since it's cryptographically broken, so a small, well-known open-source library handles that one instead. Because people frequently hash API keys, tokens, passwords, and file contents with tools like this, everything runs locally — nothing you type is ever uploaded anywhere.

Frequently Asked Questions
Is my text uploaded anywhere?
No. SHA hashes are computed with the browser's built-in Web Crypto SubtleCrypto API, and MD5 with a small local library — both run entirely on your device. Nothing you type is ever sent to a server, which matters since people often hash passwords, tokens, or file contents here.
Which hash algorithm should I use?
SHA-256 is the modern default for checksums, integrity verification, and most application use — it's the algorithm behind Git commit hashes and TLS certificates. MD5 and SHA-1 are still common for legacy compatibility and quick file-integrity checks, but are considered cryptographically broken and unsuitable for security-sensitive use like password storage. SHA-512 offers a larger digest for cases that need extra collision resistance.
Why does MD5 use a different method than the others?
The browser's native Web Crypto API deliberately doesn't implement MD5, since it's cryptographically broken and Web Crypto only exposes algorithms considered safe for real security use. This tool uses a small, well-known open-source MD5 implementation for the cases where you still need an MD5 checksum — for example, matching a legacy system's hash.
Should I use this to hash passwords for storage?
No — raw SHA-256 or MD5 are fast general-purpose hashes, not password hashes. Storing passwords requires a slow, salted algorithm built for that purpose, like bcrypt, scrypt, or Argon2. This tool is meant for checksums, integrity verification, cache keys, and similar use cases.
Does the hash update as I type?
Yes — all four hashes recompute live with every keystroke, so you can watch the output change in real time as you edit the input.
