I've received this line:


and asked to crack the password. So, I created a crack.hash file and put the following in it:


And then ran the following command in the terminal:

hashcat -m 0 -a 0 -o /crackResult.txt --remove /crack.hash /passwords.txt

And the result is:

skip line: $1$25A116L54$7/IbiL1ZsUyPwYBx/zuNv/ (line length exception)

What's my mistake?

    try with -m 500 – Jor-el Oct 11 '13 at 10:01
  • Also spelling mistake in their error (lenght should be length) XD – DarkMantis Oct 11 '13 at 10:11

This looks like a unix password string.

-m 0 is for MD5 hashes


-m 500 for Unix hashes

See https://hashcat.net/wiki/doku.php?id=hashcat

  • Very useful tip. But doesn't solve the problem... Is that because the length of the salt which is 9 chars? – Amin Saqi Oct 12 '13 at 4:45
  • This does actually answer your question. The hashcat 'line-length exception' error is a bit unclear; what it means is that it was expecting a hash of a different length (because you've asked it to crack raw MD5 (-m 0) when you have a MD5crypt (-m 500) hash. Change your syntax to use -m 500, just as mbs and Jor-el said. – Royce Williams Jan 29 '18 at 7:34
