- Method Detail
  - sign
```
byte[] sign(byte[] dccPayload,
            Instant expiration)
     throws SignatureException
```
    Creates a CWT including the CBOR encoded DCC payload and signs it.
    Note: It is the caller's responsibility to ensure that the validity of the issued DCC does not exceed the validity of the signer's certificate (see getSignerExpiration()).
    
    Parameters:
    
    dccPayload - the CBOR encoding of the DCC payload
    
    expiration - the expiration time for the DCC
    
    Returns:
    
    the CBOR encoding of the signed CWT holding the DCC payload
    
    Throws:
    
    SignatureException - for signature errors
  - getSignerExpiration
```
Instant getSignerExpiration()
```
    Gets the point in time when this signer's certificate expires. For maximum interoperability, the validity of a DCC should not stretch beyond this time.
    
    Returns:
    
    the signer certificate expiration time
  - getSignerCountry
```
String getSignerCountry()
```
    Gets the ISO-3166 country code of the signer (issuer).
    
    Returns:
    
    the country code of the signer
