By cipher is also understood a mode of secret writing .
Public ministers and other public agents frequently use ciphers in their correspondence ,
and it is sometimes very useful so to correspond in times of war .
A key is given to each minister before his departure ,
namely ,
the cipher for writing ciphers , (
chiffre chiffrant ,)
and the cipher for deciphering (
chiffre dechiffrant .)
Besides these ,
it is usual to give him a common cipher , (
chiffre banal ,)
which is known to all the ministers of the same power ,
who occasionally use it in their correspondence with each other .
3 .
When it is suspected that ,
a cipher becomes known to the cabinet where the minister is residing ,
recourse is had to a preconcerted sign in order to annul ,
entirely or in part ,
what has been written in cipher ,
or rather to indicate that the contents are to be understood in an inverted or contrary sense .
A cipher of reserve is also employed in extraordinary cases .
