## Unreleased
### Added
- Key and KeyRing methods to check if a key/keyring can Encrypt or Verify
```go
(key *Key) CanVerify() bool
(key *Key) CanEncrypt() bool
(keyRing *KeyRing) CanVerify() bool
(keyRing *KeyRing) CanEncrypt() bool
```
- SessionKey methods to encrypt/decrypt and simultaneously sign/verify with an asymmetric key (embedded signature)
```go
(sk *SessionKey) EncryptAndSign(message *PlainMessage, signKeyRing *KeyRing) ([]byte, error)
(sk *SessionKey) DecryptAndVerify(dataPacket []byte, verifyKeyRing *KeyRing, verifyTime int64) (*PlainMessage, error)
```
- The mobile helper `DecryptSessionKeyExplicitVerify` to allow using session key decryption + verification operations via gomobile
