It must implement crypto.Signer and its Public() method must return a *rsa.PublicKey or a *ecdsa.PublicKey or a ed25519.PublicKey. (A *rsa.PrivateKey, *ecdsa.PrivateKey or ed25519.PrivateKey satisfies this.)

ECDSA sometimes causes confusion when interop'ing with other libraries like OpenSSL and Java. The problem usually reduces to OpenSSL and Java use an ASN.1/DER signature format, and Crypto++ uses a IEEE P1363 format.
