Method Detail

DecodeFromBytes

public static Message DecodeFromBytes(byte[] rgbData)
                               throws CoseException

Decode a COSE message object. This function assumes that the message has a leading CBOR tag to identify the message type. If this is not true then use {#link DecodeFromBytes(byte[], MessageTag)}.

Parameters:

rgbData - byte stream to be decoded

Returns:

the decoded message object

Throws:

CoseException - on a decode failure

DecodeFromBytes

public static Message DecodeFromBytes(byte[] rgbData,
                                      MessageTag defaultTag)
                               throws CoseException

Decode a COSE message object. Use a value of MessageTag.Unknown to decode a generic structure with tagging. Use a specific value if the tagging is absent or if a known structure is passed in.

Parameters:

rgbData - byte stream to be decoded

defaultTag - assumed message type to be decoded

Returns:

the decoded message object

Throws:

CoseException - on a decode failure.

EncodeToBytes

public byte[] EncodeToBytes()
                     throws CoseException

Throws:
