How to identify and crack an IBM Lotus Notes / Domino 6 hash

IBM Lotus Notes / Domino 6 is an application 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 IBM Lotus Notes / Domino 6 entirely in your browser — your hash is never uploaded. A typical example looks like this:

(GDpO798JjmpcDFsKtcEHKb)

Cracking IBM Lotus Notes / Domino 6 with hashcat

Save the hash to a file and run hashcat in mode -m 8700. Start with a wordlist such as rockyou.txt:

echo '(GDpO798JjmpcDFsKtcEHKb)' > hash.txt && hashcat -m 8700 hash.txt /usr/share/wordlists/rockyou.txt

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

echo '(GDpO798JjmpcDFsKtcEHKb)' > hash.txt && hashcat -m 8700 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

Cracking IBM Lotus Notes / Domino 6 with John the Ripper

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

echo '(GDpO798JjmpcDFsKtcEHKb)' > hash.txt && john --format=dominosec --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
