'''Books on [[cryptography]]''' have been published sporadically and with variable quality for a long time. This is despite the [[paradox]] that secrecy is of the essence in sending confidential messages – see [[Kerckhoffs' principle]].

In contrast, the revolutions in [[cryptography]] and secure [[information transfer|communications]] since the 1970s are covered in the available literature.
