Hello Friends,

Any body help me to convert the code from Delphi to vb 6.0

const
C1 = 43941;
C2 = 16302;

function BorlandEncrypt(const S: String; Key: Word): String;
var
I: byte;
begin
SetLength(Result,Length(S));
for I := 1 to Length(S) do begin
Result := char(byte(S) xor (Key shr 8));
Key := (byte(Result) + Key) * C1 + C2;
end;
end;

function Encrypt(password : string) : string;
begin
{ ----old encrypt ----
result := '';
for i := 1 to length(password) do
result := result + char( (ord(password) xor 43) + 11 ); }

// new encrypt
password := BorlandEncrypt(password,17732);
Result := '<' + Encode64(password) + '>';
//Result := '<' + Encode64(password) + '>';
end;

function Encode64(st : string) : string;

var
i,idx : integer;

Result := '';
i := 1;
while i <= length(st) do
begin
// 1st char
idx := ord(st) and $FC shr 2;
Result := Result + Alphabet[idx+1];
// 2nd char
idx := (ord(st) 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,

hmm, it should as the encode64 function has a standard expectation.

Is the result even remotely similar?

Hello LizR,

when i m enter "pramod" as encode string in delphi code then it return me "NasK3DkF" after encoding.
