Ciphers and Symbols

Ciphers and symbols are tools used to convey information in a concealed or alternate form. A cipher is a method of transforming text to keep its meaning hidden from those not authorized to read it. For example, a simple substitution cipher replaces each letter with another letter. Symbols, on the other hand, are images or characters that represent ideas, concepts, or objects, like the sun symbolizing life. Both are used in various fields, from cryptography in secure communications to graphic design in conveying messages visually. Understanding ciphers and symbols enhances comprehension of communication methods throughout history and modern culture.
