LITCRYPT let's you hide your static string literal in the binary from naughty eyes seamlessly and protect your valuable app from illegal cracking activity.

LITCRYPT works by encrypting string literal during compile time and the encrypted string remain encrypted in both disk and memory during runtime until it will be used.

USAGE

Dependencies:

[dependencies]
litcrypt = { git = "https://github.com/anvie/litcrypt.rs" }
xor = { git = "https://github.com/anvie/xor-rs" }

Example:

fn main(){
    println!("his name is: {}", lc!("Voldemort"));
}

Before compiling, make sure you already set encryption key in XOR_ENCRYPT_KEY environment variable, e.g:

$ export XOR_ENCRYPT_KEY="myverysuperdupermegaultrasecretkey"

When compiling you may notice output like this:

[litcrypt] encrypted: `Voldemort` -> `Ow4CEAwOAAAR`

That is LITCRYPT in action encrypting every string literal placed in lc!.

Check the output binary using strings command, e.g:

$ 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 it using:

$ cargo run --example simple
