About this tool
Generates MD5, SHA-1, SHA-256, SHA-384, and SHA-512 digests of text or a file, with optional HMAC keying, all computed locally in your browser.
When you’d use it
- Verifying a downloaded file matches its published checksum.
- Producing a content hash to check whether two files or strings are identical without a byte-by-byte comparison.
- Generating an HMAC to test a webhook signature scheme during development.
Frequently asked questions
- Can I use this to hash passwords for storage?
- No, MD5 and the SHA-2 family are general-purpose hashes built to run fast, which is exactly the wrong property for password storage since a fast hash makes brute-forcing easier; use a purpose-built password hash such as bcrypt, scrypt, or Argon2 instead.
- Is MD5 still safe to use?
- Not for anything that depends on collision resistance; MD5 and SHA-1 are both cryptographically broken for that purpose. They're still fine here for non-adversarial uses like checksums, dedup keys, and cache keys.
- Does file hashing upload the file anywhere?
- No, hashing runs in your browser using the Web Crypto API, so the file itself never leaves your machine.
