Chiffre gasigasy na koa hoe Système de chiffrement par substitution tsotra kely sady fampiasan'ny sasany eto Dago indraindray.

Mampahatsiahy ny fahazazana ary indrindra indrindra ny Code César izay fianarana mamindra ho an'ireo rehetra mandalina cryptographie/cryptanalyse eo ampiandohana.

Nitsidika an'i Serasera Malagasy dia sendra azy, tsy naharitra ka niakatra ny aingampanahy... 😆😆😆

Miala any ary ny code Rust...

pub fn arb(text: &str) -> String {
    let input  = "BDFGHJKLMNPRSTVZbdfghjklmnprstvz";
    let output = "ZVTSRPNMLKJHGFDBzvtsrpnmlkjhgfdb";

    text.chars()
        .map(|c| match input.find(c) {
            Some(i) => output.chars().nth(i).unwrap(),
            None => c,
        })
        .collect()
}

fn main() {
    let str_in: &str = "LIAHARAZA AKAHEO HEREFHA FHAFHY KY FAOKA E";

    println!("Teny adika  <<<: {}", str_in);
    println!(">>> Dika mazava: {}", arb(str_in));
}

Raha hanadrana azy dia ampidiro hoe cargo run dia tsindrio return.

Teny adika  <<<: LIAHARAZA AKAHEO HEREFHA FHAFHY KY FAOKA E
>>> Dika mazava: MIARAHABA ANAREO REHETRA TRATRY NY TAONA E

Marihana fa sady fanaovana encodage no ampiasana koa amin'ny décodage pub fn arb(text: &str) -> String. Pimaso ho an'ireo namana rehetra mankafy Marika: Involution, na Fonction involutive no resaka izany 👀

Manaraka izany, tsy adino koa ny code D...

import std.stdio : writeln;
import std.algorithm : map;
import std.conv: text;
import std.string: indexOf;
import std.typecons : Yes;

string arb(string text) {
    string input  = "BDFGHJKLMNPRSTVZbdfghjklmnprstvz";
    string output = "ZVTSRPNMLKJHGFDBzvtsrpnmlkjhgfdb";
	
    return text.map!(c => indexOf(input, c, 1, Yes.caseSensitive) != -1 ? output[indexOf(input, c, 1, Yes.caseSensitive)] : c).text;
}

void main() {
    string str_in = "LIAHARAZA AKAHEO HEREFHA FHAFHY KY FAOKA E";

    writeln;
    writeln("Teny adika  <<<: ", str_in);
    writeln(">>> Dika mazava: ", arb(str_in));
}

Farany nefa tsy bitika, indro ny code Delphi...

program DelphiArb;

uses
  System.SysUtils, System.StrUtils;

function Arb(const Text: string): string;
const
  Input = 'BDFGHJKLMNPRSTVZbdfghjklmnprstvz';
  Output = 'ZVTSRPNMLKJHGFDBzvtsrpnmlkjhgfdb';
var
  CharMap: array [Char] of Char;
  Index: Integer;
begin
  for Index := Low(Input) to High(Input) do
    CharMap[Input[Index]] := Output[Index];

  Result := Text;
  for Index := 1 to Length(Result) do
    if CharMap[Result[Index]] <> #0 then
      Result[Index] := CharMap[Result[Index]];
end;

var
  StrIn: string;

begin
  StrIn := 'LIAHARAZA AKAHEO HEREFHA FHAFHY KY FAOKA E';

  Writeln('Teny adika  <<<: ', StrIn);
  Writeln('>>> Dika mazava: ', Arb(StrIn));

  Readln;

end.
