Public Member Functions
	COSEKey (byte[] xCoordinate, byte[]? yCoordinate=null, 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]
	Curve identifier - corresponds to the COSE crv parameter. Applies to both EC2 and OKP key types. For example, 1 for P-256, 6 for Ed25519, 7 for X25519. See IANA COSE Elliptic Curves registry.
int	KeyType [get, set]
	Key type - Corresponds to the COSE kty> parameter (key type). Common values: 1 for OKP (e.g. Ed25519), 2 for EC2 (e.g. P-256). See IANA COSE Key Types registry.
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. null for OKP keys (e.g. Ed25519, kty=1) which carry only an X parameter.
