MD5 Hash Generator

What is MD5?

MD5 produces 128 bits for any input: 16 raw bytes, or 32 hexadecimal characters. It is cryptographically broken, but decades of software still emit MD5 values, and reproducing one from such a system is a legitimate reason to compute it.

How to use the MD5 generator

Data

Type text or upload files. Text can be up to 100 MiB, read as UTF-8, and each file up to 2 GiB. Every input is hashed on its own.

Output

The raw digest bytes and the hexadecimal form.

Why MD5 is still here

MD5 is cryptographically broken. Collisions can be produced on demand, which means two different inputs can be made to share a digest deliberately and cheaply.

It survives because it is embedded in decades of software. Legacy file formats, old database columns, package metadata and internal deduplication schemes all still emit MD5. Reproducing a value from such a system is the use this tool is for.

MD5 alternatives

For any new cryptographic fingerprint, use BLAKE3, SHA-256 or SHA3. All are unbroken and none are meaningfully harder to use.

If the goal is detecting accidental corruption rather than resisting an attacker, CRC-32 and Adler-32 are faster and honest about being non-cryptographic. For passwords, Argon2id Hash Generator is the only appropriate option here.

Things to know about MD5

The distinction that matters: a matching MD5 can still tell you a file survived a transfer intact, because random corruption will not accidentally land on a colliding value. What it cannot do is tell you nobody changed the file on purpose.
