Functions

func AddSignaturesAndGenerateQRBaerCode

func AddSignaturesAndGenerateQRBaerCode(
	signMessage *cose.SignMessage,
	signatures [][]byte,
) (qrcode []byte, err error)

AddSignaturesAndGenerateQRBaerCode takes a SignMessage and its digests, inserts the signatures, And returns the raw baercode in bytes.

func AddSignaturesAndGenerateRawBaerCode

func AddSignaturesAndGenerateRawBaerCode(
	signMessage *cose.SignMessage,
	signatures [][]byte,
) (baerCode []byte, err error)

AddSignaturesAndGenerateRawBaerCode takes a SignMessage and its digests, inserts the signatures, And returns the raw baercode in bytes.

func CreateBaerCode

func CreateBaerCode(
	firstName string,
	lastName string,
	dob time.Time,
	procedures []credential.Procedure,
	operator string,
	result bool,
	kid []byte,
	ecdsaPrivateKey *ecdsa.PrivateKey,
	aesKey []byte,
) (qrcode []byte, err error)

CreateBaerCode creates the credential, cbors it, encrypts it, signs it and returns the byte array.

func CreateBaerCodeQR

func CreateBaerCodeQR(
	firstName string,
	lastName string,
	dob time.Time,
	procedures []credential.Procedure,
	operator string,
	result bool,
	kid []byte,
	ecdsaPrivateKey *ecdsa.PrivateKey,
	aesKey []byte,
) (qrcode []byte, err error)

CreateBaerCodeQR creates the credential, cbors it, gzips it, encrypts it, signs it, base64s it, encodes it in a QR code and returns the base64ed image.

func CreateUnsignedBaerCodeWithDigests

func CreateUnsignedBaerCodeWithDigests(
	firstName string,
	lastName string,
	dob time.Time,
	procedures []credential.Procedure,
	operator string,
	result bool,
	kid []byte,
	ecdsaPublicKey *ecdsa.PublicKey,
	aesKey []byte,
) (signMessage *cose.SignMessage, digests [][]byte, err error)

CreateUnsignedBaerCodeWithDigests creates the credential, puts in into an encrypt0 message, encrypts it, and puts it in a signed message envelope, and creates the signature digests. It doesn't sign it, nor does it add the version. The point of this function is to be able to sign the digest in a different location.

func VerifyBaerCode

func VerifyBaerCode(
	b64code string,
	publicKey *ecdsa.PublicKey,
	cryptKey []byte,
) (cred credential.Credential, version uint16, err error)

VerifyBaerCode verifies a baercode. Used mainly for testing right now, so forgive some small shortcuts, like expecting the b64 code instead of the qr code.
