Crypto

Authenticates the received Secure Network beacon using the given Beacon Key.

Calculates the AID for a given ApplicationKey.

Calculates the provisioning confirmation based on the confirmation inputs, device random, shared secret and the auth value.

Calculates the device public key based on the provisioners public key.

Calculates Electronic Code Book (ECB) for the given data and key.

Generates Node Identity Hash using the given Identity Key

Calculates the NID, EncryptionKey, PrivacyKey, NetworkID, IdentityKey, BeaconKey, PrivateBeaconKey for a given NetworkKey

/** Calculates the Friendship Credentials NID, EncryptionKey, PrivacyKey, NetworkID, IdentityKey, BeaconKey, PrivateBeaconKey for a given NetworkKey

Calculates the Session Key, Session Nonce and the Device Key based on the Confirmation Inputs, 16 or 32-byte Provisioner Random and 16 or 32-byte device Random.

Calculates the 64-bit Network ID. The Network ID is derived from the network key such that each network key generates one Network ID.

Calculates the salt based on a given input.

Calculates the shared secret based on the given public key and the local private key.

Creates a 16-bit virtual address for a given UUID.

Decodes and authenticates the received Private Beacon using the given Private Beacon Key.

Decrypts the given data with the EncryptionKey, Nonce and authenticates the generated MIC(Message Integrity Check).

Encrypts the data with the EncryptionKey , Nonce and concatenates the MIC(Message Integrity Check).

Generates a pair of Private and Public Keys using P256 Elliptic Curve.

Generates a random number of the given size in bits.

Generates a 128-bit random key using a SecureRandom.

Obfuscates or De+obfuscates given data by XORing it with PECB, which is calculated by encrypting Privacy Plaintext (encrypted data (used as Privacy Random) and IV Index) using the given key.

Returns the public key encoded as a 64-byte array
