Summary

Description

One-time pads (OTP) are used to encode/decode agent communications. They are issued in matching sets of two: one for the encoder and one for the decoder, and no two pages are alike. Each sheet contains a random key in the form of five-digit groups. Once a sheet has been used to encode a message, it is torn off the pad and destroyed. If used as designed, encryption by OTP is virtually unbreakable.
