i,idx : integer;
begin
Result := '';
i := 1;
while i <= length(st) do
begin
// 1st char
idx := ord(st[i]) and $FC shr 2;
Result := Result + Alphabet[idx+1];
// 2nd char
idx := (ord(st[i]) and $3 shl 4);
if i+1 <= length(st) then idx := idx + (ord(st[i+1]) and $F0 shr 4);
Result := Result + Alphabet[idx+1];
// 3rd char
if i+1 <= length(st) then
begin
idx := (ord(st[i+1]) and $F shl 2);
if i+2 <= length(st) then idx := idx + (ord(st[i+2]) and $C0 shr 6);
Result := Result + Alphabet[idx+1];
end
else
Result := Result + '=';
// 4th char
if i+2 <= length(st) then
begin
idx := (ord(st[i+2]) and $3F);
Result := Result + Alphabet[idx+1];
end
else
Result := Result + '=';
// next source char
Inc(i,3);
end;
end;
Thanks,
