What happened was, I was fooling around with zero-knowledge proof ideas and needed to post public keys on the Internet in textual form. I picked ed25519 keys (elliptic-curve, also known as EdDSA) so I asked the Internet “How do you turn ed25519 keys into short text strings?” The answer took quite a bit of work to find and, after I posted it, provoked a discussion about whether I was doing the right thing. So today’s question is: Should these things be encoded with the traditional PKIX/PEM serialization, or should developers just blast the key-bits into base64 and ship that?...
