C# to PHP base64 encode/decode

http://stackoverflow.com/questions/257462/c-sharp-to-php-base64-encode-decode We should probably URL Encode your Base64 string on the C# side before you send it. And URL Decode it on the php side prior to base64 decoding it. C# side byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("the string"); string enc = Convert.ToBase64String(encbuff); string urlenc = Server.UrlEncode(enc); and php side: $data = $_REQUEST['in']; $decdata = urldecode($data); $raw = base64_decode($decdata);
