Questions, answered
Is Base64 encryption?
No. Anyone can decode it without a key. Do not use Base64 to protect passwords or private information.
What is different about Base64URL?
It uses hyphens and underscores instead of plus and slash. This tool omits padding when generating Base64URL and accepts padded or unpadded input when decoding.
