I have received the decode
String from a server by using this encoding process var
data = System.Text.Encoding.UTF8.GetBytes (text); text = System.Convert.ToBase64String (data);
on my android app we using
byte  data = Base64.decode(base64data,Base64.DEFAULT);String text1 = new String (data, "UTF-8");
but when we set this setting to text view it does not show formatted.
This question already has an answer here:
I was implementing password hashing with salt, so I generated salt as binary, hashed the password, base64 encoded the password and salt then stored them into database.
Now when I am checking password, I am supposed to decode the salt back into binary data, use it to hash the supplied password, base64 encode the result and check if the result matches the one in database.
The problem is, I cannot find a method to decode the salt back into binary data. I encoded them using the Buffer.toString method but there doesn't seem to be reverse function.
Hi all I have used a Base64 Decoder (every decoder I use outputs the same format) which looks like below:
5a 2cc, a9, c, 54, 2cf, 97, b0, 1df, 148, 1005a 24, 31, 122, 198, 155, ca, 72, f5, fe, 2d1a3 13f 5a 5fa3 285.ec.285 5a 11ba3 285.ec.22b 5a 204
I thought it was HEX that it's decoded to so I have run it through a HEX to ASCII converter and it just comes out jibberish.
Any idea what that format of text is?
I am trying to get an UIImage from base64String but I am facing an interesting problem. Even though the encoded string is full, decoding it returns nil.
let base64String = imageFilePath as! String print(base64String) // returns encoded value let decodedData = NSData(base64EncodedString: base64String, options: NSDataBase64DecodingOptions(rawValue: 0)) print(decodedData) // returns nil
Edit: It goes like

For my project user send me a base64 encoded code. I need to convert into pdf document.
I am using the below code for the same.
string AsBase64String = "base64code";byte tempBytes = Convert.FromBase64String(AsBase64String);File.WriteAllBytes(@"C:\d\hh.pdf", tempBytes);
and this is working successfully but in some cases it is generating the pdf. When opening the pdf it is showing it is not valid format.
I use the same code in the below online website
Pasted the code and decode it and saved as a file and try to open in pdf. It gave the same error. Then I open the file in notepad and copy the code inside and decode it in the above website again. Then save it as file. When i open the second file it opened successfully.
Steps I done
but most of the cases first decode itself open successfully in pdf. Rare cases it needed two time decoding.
What may be the trick happening here. I am new to this base64 decoding. Please show some light on this issue
