Class ArmedProtocolMessage
- All Implemented Interfaces:
io.netty.util.ReferenceCounted
,AutoCloseable
,PartialReadMessage
,RemoteMessage
Only the message recipient can decrypt and authenticate the message by calling disarm(Crypto, SessionPair)
.
This is an immutable object.

disarm
public FullReadMessage<?> disarm(Crypto cryptoInstance, SessionPair sessionPair) throws InvalidMessageFormatException Returns a disarmed version (FullReadMessage
) of this message.Disarming will authenticate the nonce, network id, sender, sender's proof of work, recipient, agreement id, and decrypt all remaining bytes.
- Parameters:
cryptoInstance
- the crypto instance that should be usedsessionPair
- theSessionPair
to decrypt this message- Returns:
- the disarmed version of this message
- Throws:
InvalidMessageFormatException
- if disarming was not possible
-
disarmAndRelease
public FullReadMessage<?> disarmAndRelease(Crypto cryptoInstance, SessionPair sessionPair) throws InvalidMessageFormatException Returns a disarmed version (FullReadMessage
) of this message and then releases this message.Disarming will authenticate the nonce, network id, sender, sender's proof of work, recipient, agreement id, and decrypt all remaining bytes.
- Parameters:
cryptoInstance
- the crypto instance that should be usedsessionPair
- theSessionPair
to decrypt this message- Returns:
- the disarmed version of this message
- Throws:
InvalidMessageFormatException
- if disarming was not possible
-
