NimProtect is a tiny macro library for protecting sensitive strings in compiled binaries.
I built it in order to fullfill the need for compile-time string encryptor that will decrypt the strings at runtime whenever needed, just as the great but abandoned nim-strenc did.
Every string is RC4 encrypted with different MD5 key (quick disclaimer: remember that RC4 is insecure algorithm and all strings can be decrypted with some reverse engineering work).
Compile with: --benchmarkVM:on
Added splitString() macro to split and hide big suspicious strings (takes LONG to compile!)
nimble install NimProtect
import nimprotect
let c2_url = protectString("https://protected-c2-server.com")
let malicious_base64_shellcode_blob = protectString(splitString(""H4sIAAAAAAAACuy9eXgUxdYw3hMyEBCYY...")) # Takes long to compile, be patient
