Decodes a Base64 String into octets. Note that this method handles both URL-safe and
non-URL-safe base 64 encoded strings.
For the compatibility with the old version that used Apache Commons Coded's decodeBase64,
this method discards new line characters and trailing whitespaces.
Encodes binary data using a URL-safe variation of the base64 algorithm but does not chunk the
output. The url-safe variation emits - and _ instead of + and / characters.
