Input byte array has incorrect ending byte at 40

Question

I have a string that is base64 encoded. It looks like this:

eyJibGExIjoiYmxhMSIsImJsYTIiOiJibGEyIn0=

Any online tool can decode this to the pro

Answer 1

I was trying to use the strings from the args. I found that if I use arg[0].trim() that it made it work. eg

Base64.getDecoder().decode(arg[0].trim());

I guess there's some sort of whitespace that gets it messed up.
