- a 	Angriffsart: 3 - BruteForce
- m	Hashverfahren: 
	0	- MD5
	10	- MD5 ($pass.$salt)   oclhashcat erwartet immer das Format "hash:salt" unabhängig, davon wie gehashd wurde
	20 	- MD5 ($salt.$pass)   oclhashcat erwartet immer das Format "hash:salt" unabhängig, davon wie gehashd wurde
	100	- SHA1
	500 	- md5crypt, MD5(Unix), FreeBSD MD5, Cisco-IOS MD5
	3200 	- bcrypt

- 1 	CustomCharset: ?l lower $u upper $d digit $s symbol 
	-1 ?l?u ?1?1?1?1?1?1?1?1 (8 Zeichen mit groß und Kleinschreibung in allen Stellen) 
- O 	Optimized Kernel (geringere Passwortlänge, höherer Hashrate)

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
