panic: interface conversion: interface is ed25519.PublicKey, not []uint8

[stevenroose]

I'm trying to encode an ed25519.PublicKey (type PublicKey []byte) and I get the following panic.

For some reason, asn1 seems to expect a []uint8 and does not accept a []byte.

panic: interface conversion: interface is ed25519.PublicKey, not []uint8
