ASCII

ASCII is a 7-bit encoding standard which allows the representation of text using the integers 0-127.

Challenge:Using the below integer array, convert the numbers to their corresponding ASCII characters to obtain a flag.

[99, 114, 121, 112, 116, 111, 123, 65, 83, 67, 73, 73, 95, 112, 114, 49, 110, 116, 52, 98, 108, 51, 125]

Solution (python) :To solve the above challenge I used the chr() function to convert each ASCII value into character.

Code  python
ary = [99, 114, 121, 112, 116, 111, 123, 65, 83, 67, 73, 73, 95, 112, 114, 49, 110, 116, 52, 98, 108, 51, 125]
for a in ary:
    print(chr(a),end="") # crypto{ASCII_pr1nt4bl3}

After running the above python code the output flag is : crypto{ASCII_pr1nt4bl3}

Solution (rust) :

Code  rust
fn main() {
    let asci = vec![99, 114, 121, 112, 116, 111, 123, 65, 83, 67, 73, 73, 95, 112, 114, 49, 110, 116, 52, 98, 108, 51, 125,];
    let mut result: String = String::from("");
    for i in asci {
        match char::from_u32(i as u32) {
            Some(a) => result.push(a),
            None => todo!(),
            }
    }
    println!("{}", result); // crypto{ASCII_pr1nt4bl3}
}
