What Does Pigpen Cipher Mean?
The pigpen cipher is a specific type of written code that uses a variety of symbols made from spatial constructs to represent letters of an alphabet, rather than replacing one alphabetic letter with another, versus traditional ciphers.
The pigpen cipher, which dates back to the 18th century, is also known as the Masonic cipher or Freemason cipher because of its use by secretive groups that purportedly shield their practices from public scrutiny. The term also is known as the Rosicrucian cipher, is attributed to a esoteric religious group or secret society of medieval Germany.
