I have a shell script I want to encrypt in order to hide my code.



Please do not suggest SHC, because it is breaking (editor's note: explanation needed).

  • Is there a reason simply using GPG is insufficient? You can encrypt any file, not just scripts, using the method outlined here: gnupg.org/gph/en/manual/x110.html

    I presume that you do not expect to be able to execute an encrypted script?

    Sorry @MeMaTi what you are asking is not possible. A Bash script is a plain text list of commands, that need to be clear so they can be interpreted. Even if for some reason you can encrypt it in at rest file, I could easily see what your code was by doing bash -x <script.sh>. That will output every command the script is about to execute before executing it, this is very useful for debugging scripts.

I want to hide my code.




Well, ... this smells, no offence. Why do you want to hide your code is a mystery to me.



Anyway, to answer your question:




How to encrypt a shell (bash) script?




You probably wish to achieve the impossible task as was poked by Rob in his comment, I will borrow it as it stands, because from my standpoint it is sufficient:

I would only add, there is one method I know of, which you for some reason call breaking, which without knowledge of your code is impossible to establish as to why, so I will not even bring it up.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
