Method Summary

Modifier and Type	Method	Description
String	encode(byte[] dcc, Instant expiration)	Based on the CBOR encoded DCC payload and a expiration time, the method signs it, deflates it, and delivers it in Base45 encoding (with a HCERT header).
String	encode(DigitalCovidCertificate dcc, Instant expiration)	Based on the DCC payload and a expiration time, the method encodes the payload to CBOR, signs it, deflates it, and delivers it in Base45 encoding (with a HCERT header).
byte[]	sign(byte[] dcc, Instant expiration)	Given the CBOR-encoding of the DCC payload the method creates a CWT and signs it.
byte[]	sign(DigitalCovidCertificate dcc, Instant expiration)	Given the DCC payload the method creates a CWT and signs it.

Method Detail

encode

public String encode(DigitalCovidCertificate dcc,
                     Instant expiration)
              throws DGCSchemaException,
                     IOException,
                     SignatureException

Based on the DCC payload and a expiration time, the method encodes the payload to CBOR, signs it, deflates it, and delivers it in Base45 encoding (with a HCERT header).

Specified by:

encode in interface DGCEncoder

Parameters:

dcc - the contents of the DCC

expiration - the expiration of the DCC

Returns:

the Base45 encoding of the signed DCC

Throws:

DGCSchemaException - for DCC schema errors

IOException - for errors encoding data, for example CBOR related errors

SignatureException - errors concerning signing the DCC

encode

public String encode(byte[] dcc,
                     Instant expiration)
              throws IOException,
                     SignatureException

Based on the CBOR encoded DCC payload and a expiration time, the method signs it, deflates it, and delivers it in Base45 encoding (with a HCERT header).

Specified by:

encode in interface DGCEncoder

Parameters:

dcc - the contents of the DCC in its CBOR encoding

expiration - the expiration of the DCC

Returns:

the Base45 encoding of the signed DCC

Throws:

IOException - for errors encoding data, for example CBOR related errors

SignatureException - errors concerning signing the DCC

sign

public byte[] sign(DigitalCovidCertificate dcc,
                   Instant expiration)
            throws DGCSchemaException,
                   IOException,
                   SignatureException

Given the DCC payload the method creates a CWT and signs it.

Specified by:

sign in interface DGCEncoder

Parameters:

dcc - the DCC payload

expiration - the expiration time of the DCC

Returns:

the CBOR encoding of the signed DCC (CWT)

Throws:

DGCSchemaException - for DCC schema errors

IOException - for errors encoding data, for example CBOR related errors

SignatureException - errors concerning signing the DCC

sign

public byte[] sign(byte[] dcc,
                   Instant expiration)
            throws IOException,
                   SignatureException

Given the CBOR-encoding of the DCC payload the method creates a CWT and signs it.

Specified by:

sign in interface DGCEncoder

Parameters:

dcc - the DCC payload in its CBOR encoding

expiration - the expiration of the DCC

Returns:

the CBOR encoding of the signed DCC (CWT)

Throws:
