Using Ed25519 signing keys for encryption

@Benjojo12 and I are building an encryption tool that will also support SSH keys as recipients, because everyone effectively already publishes their SSH public keys on GitHub. For RSA keys, this is dangerous but straightforward: a PKCS1 v1.5 signing key is the same as an OAEP encryption key...
