My contact with assembly was during the 90s. I wanted to do cracks and keygens like the ones I saw cool groups like The Phrozen Crew and similar. I learned to use SoftIce, IDA, W32dasm and later OllyDBG to step through assembler code. I started doing simple JZ/JNZ cracks but eventually progressed to reverse engineer keygens and implement them in little C programs. My top crack was with a niche program that was distributed in 3 1/2 diskettes and checked for sectors marked as Bad (B in ScanDisk), if the disk didn't have those bad sectors it failed the copy verification. We had a 1 semester assembler class in my uni. While most of the other students didn't get why were we studying assembler, I was extatic.
