shc v4.0.1 releases: Shell script compiler

Shell Script Compiler

A generic shell script compiler. Shc takes a script, which is specified on the command line and produces C source code. The generated source code is then compiled and linked to produce a stripped binary executable.

The compiled binary will still be dependent on the shell specified in the first line of the shellcode (i.e shebang) (i.e. #!/bin/sh), thus shc does not create completely independent binaries.

shc itself is not a compiler such as cc, it rather encodes and encrypts a shell script and generates C source code with the added expiration capability. It then uses the system compiler to compile a stripped binary which behaves exactly like the original script. Upon execution, the compiled binary will decrypt and execute the code with the shell -c option.
