Is an MD2 hash reversible?

No. MD2 is a one-way hash; you cannot reverse it. You can only guess inputs and compare, which is what hashcat and John do.

What is the hashcat mode for MD2?

Use `-m -1` to tell hashcat to treat the input as MD2.

How long does it take to crack MD2?

MD2 is fast to compute, so weak passwords often fall in seconds to minutes on a GPU; strong, long passwords remain infeasible.

How to identify and crack an MD2 hash

MD2 is an raw / unsalted hash type. It is fast and typically unsalted, which makes weak passwords recoverable quickly on consumer GPU hardware. This page shows how to recognise it and the exact commands to attack it.

All identification runs locally in WebAssembly. The commands below write the hash to a local file on your machine — nothing is sent to this site.

Identifying the hash

The hash identifier on the home page detects MD2 entirely in your browser — your hash is never uploaded. A typical example looks like this:

Cracking MD2 with John the Ripper

John the Ripper can attack the same hash with the md2 format:

echo '8350e5a3e24c153df2275c9f80692773' > hash.txt && john --format=md2 --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
