username [0x63] -> 2404 -> 43a2
password [0x63] -> 2404 -> 43b5
r4: return addr: 43cc
Min len stored at 43b3
username +0x11 index 17
Max len stored at 43b4
username +0x12 index 18
43c6 must be 00
-> password must be 16 chars
so strcpy places 00 there
-> password: "passwordpassword"
username[0x11] = 01
username[0x12] = 7f
username[0x42+]= 4a44
Don't put important constants on the stack?
Strcpy does copy the last null byte
