Public Member Functions
	COSEKey (byte[] xCoordinate, byte[] yCoordinate, int algorithm=-25, int curve=1, int keyType=2)
	Initializes a new instance of the COSEKey class.

Properties
int	Algorithm [get, set]
	Algorithm identifier - Corresponds to the COSE "alg" parameter (algorithm). Represents the cryptographic algorithm used with the key. For example, -25 for ES256 (ECDSA with SHA-256). See IANA COSE Algorithms registry.
int	Curve [get, set]
	Elliptic curve identifier - corresponds to the COSE "crv" parameter (curve). Specifies the elliptic curve used for the key. For example, 1 for P-256. See IANA COSE Elliptic Curves registry.
int	KeyType [get, set]
	Key type - Corresponds to the COSE "kty" parameter (key type). According to FIDO CTAP2 Specification, this should be 2 for Elliptic Curve keys (EC2).
byte[]	XCoordinate [get, set]
	Byte array representing the X coordinate. Corresponds to the COSE "x" parameter.
byte[]	YCoordinate [get, set]
	Byte array representing the Y coordinate. Corresponds to the COSE "y" parameter.

Detailed Description
