In both of the above cases, I suspect the predominant use will be
scripts written to take a token store and import the tokens. This is
mostly a non-UI case.
RFC 6030 uses Base64 for unencrypted tokens. Base32 is also in wide use.
This is largely because, with fewer characters and no case-sensitivity,
Base32 is easier to type. I don't know of any other encodings in wide
It would be nice to support both of them, but I'm not sure how this is
possible. Suggestions are welcome.
