About this tool
The MD5 Generator computes the MD5 digest of a string in your browser using a Web Worker so even long texts hash instantly. The output is the familiar 32-character hex string, available in lower or upper case with a copy button, and matches every standard implementation.
For modern hashes use SHA256 or the SHA family generator; random digests for test data are on Random MD5 Hash.

Frequently asked questions
Is MD5 still safe?
For checksums, cache keys and deduplication, yes. For passwords, signatures or anything an attacker could forge, no: collisions are cheap to produce.
Can an MD5 hash be reversed?
Not mathematically, but short or common inputs are found in precomputed tables, which is why MD5 must not be used for passwords.
Is the hash identical to the command-line tools?
Yes. The input is encoded as UTF-8 and the digest matches md5sum, sha256sum, OpenSSL and PHP's hash() byte for byte, including for Unicode text.
Does a trailing newline or space change the hash?
Yes, any change produces a completely different digest. Check for invisible whitespace when values do not match.
Are my files or data uploaded?
No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
