Cyphering or Ciphering: Which Is Correct?

"Cyphering" is the British spelling of the American word "ciphering," which refers to the act of putting a message into a secret code or performing mathematical calculations. However, since the 1800s, the spelling "ciphering" has become more common than "cyphering" even in the UK, and some software may even tell you that the older "cyphering" is a misspelling of the now more widely accepted "ciphering." Therefore, it is a safe choice to spell the word as "ciphering" instead of "cyphering."

As a noun, a "cipher" can mean the code for writing a secret or disguised message. In this code or system of secret writing, letters and symbols are substituted for other characters to conceal the meaning of the text. In mathematics and computing, a "cipher" (noun) can refer to the number zero or a null value.

In a broader sense, "cipher" (noun) can refer to a method, trick, or way of doing something, often with the implication of it being hidden or difficult to understand.
