Default Mask:
If -a 3 is requested without specifying a mask, the following default mask is used:
?1?2?2?2?2?2?2?3?3?3?3?d?d?d?d
Bereits berechnete Hash-Werte:
Hashcat speichert bereits berechnete Werte in ~/.local/share/hashcat/hashcat.potfile
MD5-Hash erzeugen:
echo -n „testTest“ | openssl md5 > hashfile_md5_testTest
Hashcat starten:
hashcat -a 3 -m 0 hashfile_md5_testTest -1 ?l?u ?1?1?1?1?1?1?1?1 -0
