MD5 / SHA-256 Hash Generator

Generate MD5 and SHA-256 hashes of any text instantly. Useful for checksums, deduplication, and verifying data integrity. SHA-256 uses your browser's native Web Crypto API; no data is uploaded.

All computations run locally in your browser, no data uploaded to server.

How To Use

  1. Paste or type the text you want to hash.
  2. Choose MD5 or SHA-256.
  3. Click Generate hash to see the hex digest.
  4. Copy the result — for MD5, each format row (32/16-bit, lower/upper) has its own Copy button.

Usage Example

Input:

Hello, devtoolkit!

SHA-256 digest (32 bytes, hex):

f295446766779f3832ad91f78defafe987fe529759266941e46f5eb2cd8468dc

MD5 digest (16 bytes):

674f27bd44c7382bea7ab038083175f5

Frequently Asked Questions

Which hash should I use?

Prefer SHA-256 for modern checksums. MD5 is faster but cryptographically broken, so use it only for non-security tasks like deduplication.

Is my text uploaded?

No. SHA-256 runs through your browser's crypto.subtle and MD5 is computed locally. Nothing is sent to a server.

What if SHA-256 is not available?

SHA-256 uses your browser's native Web Crypto for speed when it is available, and automatically falls back to a built-in JavaScript implementation otherwise — so it works on any connection, including plain HTTP. MD5 is always computed locally.
