What is runic cipher?

Runic Cipher is a encryption method that involves the use of the alphabets of the Runic script. Runic is an early form of writing used by Germanic-speaking peoples from about the 3rd century CE to the 16th or 17th century CE. In a Runic cipher, the letters of the alphabet are replaced with runic characters.

There are several different variations of the Runic cipher. One common method involves using the Younger Futhark, a runic alphabet of 16 characters used during the Viking Age. Each runic character stands for a different letter of the alphabet.

To encode a message using the Runic cipher, a person replaces each letter in the original message with its corresponding runic character. The recipient would use a key to convert the runic characters back into the original message.

The Runic cipher was used primarily during the medieval period in Scandinavia, Germany, and England. It was used in both military and diplomatic communications, as well as in personal messages. Today, the Runic cipher is considered a historical encryption method and is no longer commonly used.
