The PublicKey "from" implementations didn't reverse the "encode" operation from PublicKey::as_byte, and so a stand-alone PublicKey could not be correctly constructed from bytes. (PublicKeys constructed from PrivateKeys were fine.) With this change the RFC8032 test-vectors in rfc8032.rs all pass even when verifying the signatures using a PublicKey constructed from bytes. A couple of unit-tests needed updating as not all 57-byte octet sequences are valid Ed448 public keys (which is correct).

I would love to see this PR to get merged into master and released as a new version since I really need the public key construction. @pdh11 thanks for this PR :) |

With this change an (unpublished) rust TLS client library can now successfully
connect to a GnuTLS server using ed448-rust signatures for certificates and ECDHE
parameters.
