String to MD5

Generate the MD5 hash of any text instantly. Free online MD5 tool — plus why MD5 is fine as a checksum but broken for security.

Paste text and get its MD5 digest — a 32-character hex fingerprint. MD5 is fast and fine for detecting accidental changes, but broken for anything security-sensitive.

Use MD5 only as a checksum

MD5 is great for a quick non-adversarial integrity check — confirming a file downloaded without corruption, or deduplicating content. It is fast and widely supported.

Why it is not secure

Researchers can cheaply craft two different inputs with the same MD5 (a collision), so it must never be used for signatures, certificates, or password hashing. For those, use SHA-256 or a proper password KDF.

FAQ

Is MD5 safe?›
Only as a non-security checksum. It is broken for anything that must resist tampering — use SHA-256 there.
Can MD5 be reversed?›
No, but weak or common inputs can be guessed from precomputed tables, which is another reason not to use it for passwords.
