Methods

Name	Description
Authenticate(Byte[])	Returns the result of computing HMAC-SHA-256 on the given message using the AuthenticationKey. With protocol 1, the result is the first 16 bytes of the HMAC, and with protocol 2 it is the entire 32-byte result.
Authenticate(Byte[], Byte[])	Returns the result of computing HMAC-SHA-256 on the given message using the provided keyData. With protocol 1, the result is the first 16 bytes of the HMAC, and with protocol 2 it is the entire 32-byte result.
Decrypt(Byte[], Int32, Int32)	Returns the AES-256-CBC decryption of ciphertext using an IV specified by the protocol and the EncryptionKey. With protocol 1 the IV is all 00 bytes. With protocol 2, it is the first block size bytes of ciphertext.
DeriveKeys(Byte[])	The key derivation function to run while performing ECDH. This will derive both the EncryptionKey and the AuthenticationKey.
Dispose(Boolean)	Release resources, overwrite sensitive data.
Encrypt(Byte[], Int32, Int32)	Returns the AES-256-CBC encryption of plaintext using an IV specified by the protocol and the EncryptionKey. With protocol 1 the IV is all 00 bytes. With protocol 2, it is a new, random value.
