How to identify and crack an SHA-384 hash

SHA-384 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 SHA-384 entirely in your browser — your hash is never uploaded. A typical example looks like this:

8b04ec6cdbb08f9aa7d5e6bcd47b48a3da6f7b5b3f6e3a3e7d

Cracking SHA-384 with hashcat

Save the hash to a file and run hashcat in mode -m 10800. Start with a wordlist such as rockyou.txt:

echo '8b04ec6cdbb08f9aa7d5e6bcd47b48a3da6f7b5b3f6e3a3e7d' > hash.txt && hashcat -m 10800 hash.txt /usr/share/wordlists/rockyou.txt

Add a rule set to mutate dictionary words (capitalisation, leetspeak, appended digits) and dramatically widen coverage:

echo '8b04ec6cdbb08f9aa7d5e6bcd47b48a3da6f7b5b3f6e3a3e7d' > hash.txt && hashcat -m 10800 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

Cracking SHA-384 with John the Ripper

John the Ripper can attack the same hash with the raw-sha384 format:

echo '8b04ec6cdbb08f9aa7d5e6bcd47b48a3da6f7b5b3f6e3a3e7d' > hash.txt && john --format=raw-sha384 --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
