Example

To use the library, you have to provide a COSE as binary data. Next, it will be decoded and validated against the DGC Spec.

As a result you will receive a CoseResult, which contains

• a map which contains the payload
• a bool verified, which indicates that the COSE signature could be verified
• a CoseErrorCode errorCode, that indicates the type of error

// binary representation of the COSE structure
final List<int> cose = ...
// Map containing kid => Base64 encoded DER, or String PEM.
final Map<String, String> keys = ...

var result = Cose.decodeAndVerify(cose, keys);

print(result);
