Method Summary

Modifier and Type	Method	Description
Barcode	encodeToBarcode(byte[] dcc, Instant expiration)	Based on the CBOR encoded DCC payload and a expiration time, the method signs it, deflates it, Base45 encodes it, and finally delivers it as a barcode.
Barcode	encodeToBarcode(DigitalCovidCertificate dcc, Instant expiration)	Based on the DCC payload and a expiration time, the method encodes the payload to CBOR, signs it, deflates it, Base45 encodes it, and finally delivers it as a barcode.

Method Detail

encodeToBarcode

Barcode encodeToBarcode(DigitalCovidCertificate dcc,
                        Instant expiration)
                 throws DGCSchemaException,
                        IOException,
                        SignatureException,
                        BarcodeException

Based on the DCC payload and a expiration time, the method encodes the payload to CBOR, signs it, deflates it, Base45 encodes it, and finally delivers it as a barcode.

Parameters:

dcc - the contents of the DCC

expiration - the expiration of the DCC

Returns:

a barcode containing 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

BarcodeException - errors creating the barcode

encodeToBarcode

Barcode encodeToBarcode(byte[] dcc,
                        Instant expiration)
                 throws IOException,
                        SignatureException,
                        BarcodeException

Based on the CBOR encoded DCC payload and a expiration time, the method signs it, deflates it, Base45 encodes it, and finally delivers it as a barcode.

Parameters:

dcc - the contents of the DCC in its CBOR encoding

expiration - the expiration of the DCC

Returns:

a barcode containing the signed DCC

Throws:

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

SignatureException - errors concerning signing the DCC

BarcodeException - errors creating the barcode
