Detailed explanation-1: -Cryptography is the process of converting between readable text, called plaintext, and an unreadable form, called ciphertext . This occurs as follows: The sender converts the plaintext message to ciphertext. This part of the process is called encryption (sometimes encipherment ).
Detailed explanation-2: -Answer: Encryption converts plain text into cipher text. Explanation: The process of converting between plaintext, which is readable text, and ciphertext, which is unreadable text, is known as cryptography.
Detailed explanation-3: -A cryptographic system takes plaintext as input and produces ciphertext as the result. In cryptography, algorithms convert ciphertext into plaintext and vice versa.
Detailed explanation-4: -In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption-a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.
Detailed explanation-5: -The process of transforming plain text or data into cipher text that cannot be read by anyone other than the sender and the intended receiver is called Encryption.
