Key Material Formats
HUKS defines a set of formats for the material of key pairs, public keys, and private keys of different cipher algorithms.
Key Pair Material
Key pair material = Key pair material header + Original key pair material
The following uses the RSA key as an example. The application needs to apply for a Uint8Array and assign the variables to the corresponding positions based on the memory structure of the RSA key pair material.

Public Key Material
When a public key is exported or imported, the key material is encapsulated in the DER format defined in X.509.
The following is ECC public key in EDR format:
let eccP256PubKey = new Uint8Array([
0x30, 0x59, 0x30, 0x13, 0x06, 0x07, 0x2a, 0x86, 0x48, 0xce, 0x3d, 0x02, 0x01, 0x06, 0x08, 0x2a,
0x86, 0x48, 0xce, 0x3d, 0x03, 0x01, 0x07, 0x03, 0x42, 0x00, 0x04, 0xc0, 0xfe, 0x1c, 0x67, 0xde,
0x86, 0x0e, 0xfb, 0xaf, 0xb5, 0x85, 0x52, 0xb4, 0x0e, 0x1f, 0x6c, 0x6c, 0xaa, 0xc5, 0xd9, 0xd2,
0x4d, 0xb0, 0x8a, 0x72, 0x24, 0xa1, 0x99, 0xaf, 0xfc, 0x3e, 0x55, 0x5a, 0xac, 0x99, 0x3d, 0xe8,
0x34, 0x72, 0xb9, 0x47, 0x9c, 0xa6, 0xd8, 0xfb, 0x00, 0xa0, 0x1f, 0x9f, 0x7a, 0x41, 0xe5, 0x44,
0x3e, 0xb2, 0x76, 0x08, 0xa2, 0xbd, 0xe9, 0x41, 0xd5, 0x2b, 0x9e]);
Private Key Material
The private key material is in the same format as the key pair material. When the private key material is encapsulated, the public key length in the header of the key pair material is set to 0 and original key pair material and the private key material are combined.
Private key material = Header of the key pair material + Original private key material
The following uses the RSA private key material as an example:
let rsa2048PrivateKeyMaterial = new Uint8Array([
0x01, 0x00, 0x00, 0x00, // Key algorithm: huks.HuksKeyAlg.HUKS_ALG_RSA = 1

0x00, 0x00, 0x00, 0x00, // Length of the public key exponent e (byte): 0
