vxZIP Decoder Architecture
Decoders are ELF executables for x86-32
- Can be written in any language, safe or unsafe
- Compiled using ordinary tools (GCC)
Decoders have access to five “system calls”:
- read stdin, write stdout, malloc, next file, exit
- open files, windows, devices, network connections, ...
- get system info: user name, current time, OS type, ...
