I came across this URL (Uniform Resource Locator) today that has some base64 encoded data in it. Curious as to what it might be, I tossed the data into a base64 decoder only to have it reject the data as bad.
Okay. It certainly looks like base64 encoded data. But the data doesn't match the RFC-2045 [1] specification. Don't tell me there's more than one … oh for heaven's sake [2]! Really? Thirteen variations?
Standards! There are so many to choose from!
