1. A method for asynchronous side channel cipher renegotiation, comprising:
establishing, by a first computing device, a first communication channel and a second communication channel with a second computing device, where the first communication channel is an encrypted tunnel and packages exchanged using the encrypted tunnel are encrypted using a first cipher;
receiving, by a receiver of the first computing device, a renegotiation request from the second computing device using the second communication channel, where the renegotiation request includes at least a password value and a relative time;
generating, by a processor of the first computing device, a second cipher using at least an encryption protocol and the password value;
receiving, by the receiver of the first computing device, a new encrypted packet from the second computing device using the first communication channel; and
decrypting, by the processor of the first computing device, the new encrypted packet using the second cipher.
