LITCRYPT 
Is a short name of "Literal Encryption", a Rust proc macro that encrypts text using a basic XOR method. It protect plain text from static analysis tools and helps keep your important app safe from cracking activity.
LITCRYPT encrypts strings when compiling, keeping them encrypted in both disk and memory while running, and only decrypting them when needed.
USAGE
Dependencies:
[dependencies]
litcrypt = "0.3"Example:
#[macro_use]
extern crate litcrypt;
use_litcrypt!();
fn main(){
println!("his name is: {}", lc!("Voldemort"));
}use_litcrypt! macro call should be called first for initialization before you can
use lc! macro function. The first parameter is your secret key used for encrypt your
literal string. This key is also encrypted and will not visible under static analyzer.
Please take note that you need to set your encryption key using environment variable
LITCRYPT_ENCRYPT_KEY before compile:
e.g:
$ export LITCRYPT_ENCRYPT_KEY="myverysuperdupermegaultrasecretkey"
Litcrypt will encrypt each string written inside lc! statically.
Check the output binary using strings command to verify:
$ strings target/debug/my_valuable_app | grep Voldemort
If the output is blank then your valuable string in your app is safe from static analyzer tool like Hexeditor etc.
For working example code see ./examples directory, and test using:
$ cargo run --example simple
