SessionKeyAndNonce (I2P Anonymous Network - Java Documentation - Version 1.5.0)

java.lang.Object
- net.i2p.data.SimpleDataStructure
- - net.i2p.data.SessionKey
  - - net.i2p.router.crypto.ratchet.SessionKeyAndNonce

All Implemented Interfaces:

DataStructure
```
class SessionKeyAndNonce
extends SessionKey
```
A session key is 32 bytes of data. Nonce should be 65535 or less. This is what is returned from RatchetTagSet.consume(). RatchetSKM puts it in a RatchetEntry and returns it to ECIESAEADEngine.

Since:

0.9.44
