Welcome to the Rot13 in Rust page! Here, you'll find the source code for this program as well as a description of how the program works.
use std::env;
fn rot13(input: String) -> String {
let mut output = String::new();
for character in input.chars() {
let offset;
if character.is_ascii_lowercase() {
offset = 'a' as u8;
}
else if character.is_ascii_uppercase() {
offset = 'A' as u8;
}
else {
output.push(character);
continue;
}
let mut rotated = character as u8;
rotated -= offset;
rotated += 13;
rotated %= 26;
rotated += offset;
output.push(rotated as char);
}
return output;
}
fn main() {
let args: Vec<String> = env::args().collect();
if (args.len() == 1) {
println!("Usage: please provide a string to encrypt");
return;
}
let input = args[1].to_string();
if (input.is_empty()) {
println!("Usage: please provide a string to encrypt");
return;
}
let output = rot13(input);
println!("{}", output);
}
