Exploring Early Ciphers: Atbash, Pigpen, Vigenère, and Polybius Techniques

This document delves into early cipher techniques used for plaintext encryption, focusing on methods such as the Atbash, Pigpen, Vigenère, and Polybius ciphers. The Atbash cipher transforms the word "MALTEPE" into "NZOGVKV". In contrast, the Pigpen cipher encodes "sadi evren seker" with a unique graphical substitution. The Vigenère technique uses the key "HUSEYIN" to convert "MALTEPE" into "TUDXCXR". Lastly, the Polybius square is utilized for positional encoding, showcasing the versatility and creativity of early cryptographic methods.
