All Implemented Interfaces
org.apache.sshd.common.cipher.Cipher, org.apache.sshd.common.cipher.CipherInformation, org.apache.sshd.common.keyprovider.KeySizeIndicator, org.apache.sshd.common.AlgorithmNameProvider
Represents a no-op cipher. This cipher can not really be used during authentication and should only be used after, so that authentication remains secured, but not the remaining of the exchanges.
