Editing Pigpen cipher (section)

==Insecurity==
The Pigpen cipher offers little [[cryptographic]] security. It differentiates itself from other simple [[monoalphabetic substitution]] ciphers solely by its use of symbols rather than letters, the use of which fails to assist in curbing [[cryptanalysis]]. Additionally, the prominence and recognizability of the Pigpen leads to it being arguably worthless from a security standpoint. Knowledge of Pigpen is so ubiquitous that an interceptor might not need to actually ''break'' this cipher at all, but merely ''decipher'' it, in the same way that the intended recipient would.

Due to Pigpen's simplicity, it is very often included in children's books on ciphers and secret writing.<ref name="Gardner">Gardner</ref>
