I'm struggling with creating a mask to brute-force using Hashcat a password of variable length, but with a known suffix.
Say the known suffix is
123$ but the variable-length "prefix" can contain between 4 and 7 characters (i.e. total length 8 to 11 characters)
Do I need to define a charset? I'm aware of "increment mode", but how do I stipulate a variable length mask - looking at examples it seems to only let me define each character independently, how would this work with a variable length?
