FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Ciphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can’t be read until it has been converted into plaintext (decrypted) with a key. The decryption cipher is an algorithm that transforms the ciphertext back into plaintext.

Detailed explanation-2: -In cryptography, algorithms transform plaintext into ciphertext, and ciphertext into plaintext. These respective processes are called encryption and decryption. The basis for using such a system is to ensure that the data can only be read by its intended recipient.

Detailed explanation-3: -The process of transforming plaintext into ciphertext using a cryptographic algorithm and key. The process of changing plaintext into ciphertext using a cryptographic algorithm for the purpose of security or privacy.

Detailed explanation-4: -➢ Symmetric encryption is a form of cryptosystem in which encryption and decryption are performed using the same key. ➢ It is also known as conventional encryption. ➢ Symmetric encryption transforms plaintext into cipher text using a secret key and an encryption algorithm.

Detailed explanation-5: -In cryptography, plaintext is usually ordinary readable text before it is encrypted into ciphertext, or readable text after it is decrypted. Data input to or output from encryption algorithms is not always plaintext.
