What is MD5?

A one-way fingerprint of any text.
MD5 (Message-Digest Algorithm 5) produces a 128-bit hash from any input. It's widely used for checksums and data-integrity checks. It is not collision-resistant — don't use MD5 for password hashing or digital signatures. For that, use bcrypt/argon2 or SHA-256.
The same input always produces the same MD5 hash, but the tiniest change in input produces a completely different hash. An MD5 hash is typically displayed as a 32-character hexadecimal string.
Frequently asked
Is MD5 secure?
No. MD5 is cryptographically broken — practical collision attacks have existed since 2004 — so never use it for passwords, signatures, or anything an attacker could forge. It's still fine as a fast checksum against accidental corruption.
Can an MD5 hash be reversed?
Not directly — MD5 is one-way. But because it's fast and unsalted, short or common inputs are easily recovered from precomputed lookup tables, which is another reason not to hash passwords with it.
MD5 or SHA-256 — which should I use?
Use SHA-256 for anything security-related. Reach for MD5 only when you need a quick, non-security fingerprint and both sides agree on it.
