Introduction
In this tutorial we learn how to install shc on Kali Linux.
What is shc
shc is:
SHC is a generic shell script compiler.
It 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.
The compiled binary will still be dependent on the shell specified in
the first line of the shell code, 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 shells’ -c option.
There are three methods to install shc on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
