Yes, I stumbled across it a while ago trying to decrypt YAR into something. The online cipher tool I was using was set to encrypt instead of decrypt and all of sudden I saw CIA as the result. I’ve posted it on this sight before under the K3/YAR heading.
Also Encrypting YAR with palimpsest results in OHM
OHM-the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
I thought that was interesting as well considering Sanborn’s fascination with electro magnetism and such.
