Sherlocked v3. by elfmaster@zoho.com 2014 from Bitlackeys About: Sherlocked is a protector for scripts of any type. It uses a simple xor cipher with a provided key. Unless '-r' option is used, the key is stored (encrypted) within the binary and the binary will run without the user providing the key. Sherlocked takes your script, encrypts it, and stores it in an output ELF x86_64 executable file. The ELF executable at runtime will decrypt the script and temporarily write it to a random file in /tmp. It passes the script and cmdline args to the interpreter, and then deletes the script. NOTE: Protected files that are also locked with a password (e.g. -r) won't accept cmdline args. In other words you can't password protect your script and expect it to take cmdline args. This is a temporary restriction due to my lazy programming since there is no quick way to seperate the command line args from the password you would have to give on the command line. If you don't like this, then implement it yourself :) Compile: make Usage: ./sherlocked <infile> <outfile> <key> <interpreter> [-r] Options: <infile> <-> The script file <outfile> <-> The protected output file <key> <-> The key string used to encrypt the script [-r] <-> Require the user who runs the protected executable supplies the key for it to run I.E ./script.elf <key>
