remove the new line characters to the encoded base64 string


Failed to remove the new line characters to the encoded base64 string,

As CRYPT_STRING_NOCRLF is used but it is not supported in Windows Server 2003 and Windows XP, How to get the desired result in windows xp and 2003 without using CRYPT_STRING_NOCRLF

Procedure TForm1.Button1Click(Sender: TObject);
var
  sLen : Cardinal;
  temp : String;
  a : Array[0..1] of Byte = ($00,$00);
Begin
  CryptBinaryToStringA(@a[0],Length(a),CRYPT_STRING_BASE64 Or CRYPT_STRING_NOCRLF,nil,@sLen);
  SetLength(temp,sLen);
  CryptBinaryToStringA(@a[0],Length(a),CRYPT_STRING_BASE64 Or CRYPT_STRING_NOCRLF ,@temp[1],@sLen);
  ShowMessage(temp);
end; 

CryptBinaryToString


Solution

  • Isn't it just to do this:

    uses StrUtils;
    
    Procedure TForm1.Button1Click(Sender: TObject);
    var
      sLen : Cardinal;
      temp : String;
      a : Array[0..1] of Byte = ($00,$00);
    Begin
      CryptBinaryToStringA(@a[0],Length(a),CRYPT_STRING_BASE64 Or CRYPT_STRING_NOCRLF,nil,@sLen);
      SetLength(temp,sLen);
      CryptBinaryToStringA(@a[0],Length(a),CRYPT_STRING_BASE64 Or CRYPT_STRING_NOCRLF ,@temp[1],@sLen);
      temp:=StrReplace(temp,#13#10,'');
      ShowMessage(temp);
    end;
    

    ie. replace the CR/LF pairs with empty strings to remove it from the output string?
