[DanielG]

don't specify --hex-charset

[byte7a]

don't specify --hex-charset

Then the output is:
aaaa
aaab
aaa3

But i need to print as hex pairs like that:
abababab
ababab36
ababab54

don't specify --hex-charset

Then the output is:
aaaa
aaab
aaa3

But i need to print as hex pairs like that:
abababab
ababab36
ababab54

for this more specific purpose you have to generate your own dictionary with hashcat utils like this

file

Code:

ab
36
54
ee

using combinator to generate all possibilitis up to your desired length (given your example the fastest way is this)

combinator file file > 2
combinator 2 2 > 4

after this in file 4 there are all "hex-string-possibilities" with your given input ab, 36, 54, ee, so 4^4, 256 possibilities
