How to identify and crack a Sybase ASE hash

Sybase ASE is a database 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 Sybase ASE entirely in your browser — your hash is never uploaded. A typical example looks like this:

0xc0074BE393C06BE420AD541BB5879667D8CB39F2DBDBB7B0563CB6C9

Cracking Sybase ASE with hashcat

Save the hash to a file and run hashcat in mode -m 8000. Start with a wordlist such as rockyou.txt:

echo '0xc0074BE393C06BE420AD541BB5879667D8CB39F2DBDBB7B0563CB6C9' > hash.txt && hashcat -m 8000 hash.txt /usr/share/wordlists/rockyou.txt

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

echo '0xc0074BE393C06BE420AD541BB5879667D8CB39F2DBDBB7B0563CB6C9' > hash.txt && hashcat -m 8000 hash.txt /usr/share/wordlists/rockyou.txt -r /usr/share/hashcat/rules/best64.rule

Cracking Sybase ASE with John the Ripper

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

echo '0xc0074BE393C06BE420AD541BB5879667D8CB39F2DBDBB7B0563CB6C9' > hash.txt && john --format=sybasease --wordlist=/usr/share/wordlists/rockyou.txt hash.txt
