The word cipher in former times meant zero and had the same origin: Middle French as cifre and Medieval Latin as cifra, from the Arabic ifr = zero (see Zero Etymology). Cipher was later used for any decimal digit, even any number. There are many theories about how the word cipher may have come to mean encoding:

Encoding often involved numbers.
The Roman number system was very cumbersome because there was no concept of zero (or empty space). The concept of zero (which was also called cipher), which we all now think of as natural, was very alien in medieval Europe, so confusing and ambiguous to common Europeans that in arguments people would say talk clearly and not so far fetched as a cipher. Cipher came to mean concealment of clear messages or encryption.
The French formed the word chiffre and adopted the Italian word zero.
The English used zero for 0, and cipher from the word ciphering as a means of computing.
The Germans used the words Ziffer ...more
