HMAC-SHA1 with binary Key

[philsmd]

pro tip with hashcat 3.6+ or newer you could just use the --encoding-to command line option (if the word list is not already using the correct encoding):

Code:

$ cat hash.txt

$ cat dict.txt
hashcat
$ xxd -p dict.txt

$ hashcat -m 160 --hex-salt --encoding-to=utf-16le hash.txt dict.txt
