MD5 Hash

Computes the MD5 hash of text (non-cryptographic; legacy use).

MD5 Hash computes the MD5 digest of any text you paste in, returning the standard 32-character lowercase hexadecimal checksum. It's handy for generating quick checksums, comparing values, or working with legacy systems that still rely on MD5. Note that MD5 is non-cryptographic and should not be used for password storage or security-sensitive hashing.

Common uses

  • Generate a checksum to compare two pieces of text for equality
  • Reproduce or verify MD5 digests expected by a legacy API or database column
  • Create cache keys or deduplication identifiers from string content
  • Debug code that produces MD5 hashes by checking the expected output for a known input
  • Compute ETag-style or fingerprint values for short strings during development

FAQ

Is my data sent to a server?

No. The MD5 hash is calculated entirely in your browser using a JavaScript implementation, and nothing you type is uploaded or stored anywhere.

What format is the output?

The result is the MD5 digest as a 32-character lowercase hexadecimal string, which is the conventional MD5 representation.

Is MD5 secure for passwords?

No. MD5 is considered cryptographically broken and is unsuitable for passwords or security-sensitive use. It remains useful only for non-cryptographic purposes like checksums, fingerprints, and legacy compatibility.

Does it hash files or only text?

This tool hashes the text you enter in the input field. It treats the input as a string and returns the MD5 digest of that text.

Why isn't this using the Web Crypto API?

MD5 is not provided by the browser's built-in Web Crypto API, so the tool uses a small pure-JavaScript MD5 implementation that still runs fully client-side.
