The TSEC/KL-7, also known as Adonis was an off-line non-reciprocal rotor encryption machine. The KL-7 had rotors to encrypt the text, most of which moved in a complex pattern, controlled by notched rings. The non-moving rotor was fourth from the left of the stack. The KL-7 also encrypted the message indicator.

==History and development== In 1945, the Army Security Agency (ASA) initiated the research for a new cipher machine, designated MX-507, planned as successor for the SIGABA and the less secure Hagelin M-209. In 1949, its development was transferred to the newly formed Armed Forces Security Agency (AFSA) who named the machine AFSAM-7, which stands for Armed Forces Security Agency Machine No 7.
