An ed25519 public key is 32 bytes. 32 bytes in base32 encoding is 56 characters (or 52 with the '=' padding removed). Do we want a different URL encoding or are we happy with addresses like: mfrggzdfmztwq2lknnwg23tpobyxe43uov3ho6dzpjaueq2eivda.onion ?

What was the other encoding that Dan tested? Was that one shorter but with crazier characters, maybe?

Y64?

"Y64 is a base64 variant used at Yahoo! when base64 information needs to be transmitted as part of a GET request. Regular base64 has three characters that aren’t URL-safe: plus (+), slash (/), and equals (=). Y64 encoding replaces these with dot (.), underscore (_), and dash (-), respectively."

Or would case sensitivity be too crazy?
