Question

I am trying to decode a Base64 string from my authentication headers in Java. I am certain that the request being sent has a valid Base64 encoded string in the authentication header. Here is my decoding code:

HttpServletRequest request = (HttpServletRequest) req;
byte[] test = new Base64().decode(request.getHeader("Authorization"));

Before I decode the request it looks like this Basic dXNlcjpmZGdmcw==

After I try to decode it it looks like this: «"qÕÍ•È陑™Ì

I am not sure what I am doing wrong, and no matter what decode utility I use it always ends up looking like gibberish. Thanks for reading.

Answer 1

sun.misc.BASE64Decoder decoder = new sun.misc.BASE64Decoder();
System.out.println(new String(decoder.decodeBuffer("dXNlcjpmZGdmcw==")));

Prints user:fdgfs. Note: Decode Base64 data in Java for better solutions. Have you checked what is returned by:

request.getHeader("Authorization")

?
