В общем пытаюсь перенести js код в делфи, но при проверки выдаёт обрезок в delphi, не весь текст шифрует
Тут js
function rc4(key, str) {
/* jshint bitwise: false */
var s = [], j = 0, x, res = '';
for (var i = 0; i < 256; i++) {
s[i] = i;
}
for (i = 0; i < 256; i++) {
j = (j + s[i] + key.charCodeAt(i % key.length)) % 256;
x = s[i];
s[i] = s[j];
s[j] = x;
}
i = 0;
j = 0;
for (var y = 0; y < str.length; y++) {
i = (i + 1) % 256;
j = (j + s[i]) % 256;
x = s[i];
s[i] = s[j];
s[j] = x;
res += String.fromCharCode(str.charCodeAt(y) ^ s[(s[i] + s[j]) % 256]);
}
return res;
}
а тут delphi
function RC4Encrypt(key, Text: String): String;
var
i, j, X, Y: Integer;
s: array [0 .. 255] of Integer;
charCode: Integer;
ct: String;
ctInt: Integer;
begin
for i := 0 to 255 do
begin
s[i] := i;
end;
j := 0;
for i := 0 to 255 do
begin
charCode := Ord(char(key[(i MOD Length(key)) + 1]));
j := (j + s[i] + charCode) MOD 256;
X := s[i];
s[i] := s[j];
s[j] := X;
end;
i := 0;
j := 0;
ct := '';
for Y := 0 to (Length(Text) - 1) do
begin
i := (i + 1) MOD 256;
j := (j + s[i]) MOD 256;
X := s[i];
s[i] := s[j];
s[j] := X;
ctInt := Ord(char(Text[Y + 1])) xor (s[((s[i] + s[j]) MOD 256)]);
ct := concat(ct, String(Chr(ctInt)));
end;
Result := ct;
end;
