PinUvAuthProtocolTwo()	Constructs a new instance of PinUvAuthProtocolTwo.

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[], int, int)	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(bool)	Release resources, overwrite sensitive data.
Encrypt(byte[], int, int)	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.
