In its simplest form it uses a shifted alphabet. This is often called a Caesar Cipher, as it was used by Julius Caesar for communication with his generals. It is also known as Strip Cipher, as some implementations use sliding alphabets printed on strips (made of paper, plastic or wood). Subsitution tables, matrix ciphers and some versions of the One-Time Pad (OTP) can also be seen as manual cipher methods. Over the years hand methods have been used for a variety of purposes, with varying degrees of success. Bewlo are some examples.
