[hashcat] MD5 frrom Linux

[jAm]

Hi,

I have this /etc/shadow from a Suse Linux (hash has been volontary modified)

$2a$10$71vP25lx/c4IN9t12FFx0eosfpc2qA7.6sFtBK9PoAAeFjq7Bvrx.

I tried hashcat bruteforce with -m 500, but it doen't work : "Skipping line"

Is my hash not the good format or I don't put the right -m parameter ?

Thank you.
