Frequently asked questions
Why is MD5 still here if it's broken?+
MD5 is cryptographically broken for security but is still required by tons of legacy software — htpasswd, MySQL native_password, OpenStack hashes, etc. We keep it for compatibility with a clear warning to never use it for new code.
Can I hash binary files?+
This page hashes text only. For files use sha256sum (Linux/macOS) or CertUtil -hashfile (Windows). The output is byte-identical for matching input.
Does the tool send my text anywhere?+
No. All four algorithms run in your browser — SHA-1/256/512 via the WebCrypto API, MD5 via an inline RFC 1321 implementation. Nothing is uploaded.
