Transforming a Plain Text message to Cipher Text - GeeksForGeeks

WebA cipher is an algorithm which is used to encrypt or decrypt the data. Plain text is converted in cipher text with help of this. The transforming process is performed using a key. This key is like a pattern to encrypt the data. If we wanted to decrypt the data then we need to reverse the process. Example: The history of cryptography began thousands of years ago. Cryptography uses a variety of different types of encryption. Earlier algorithms were performed by hand and are substantially different from modern algorithms, which are generally executed by a machine. Historical pen and paper ciphers used in the past are sometimes known as classical ciphers. They include:
