When we decrypt it, the fault will affect the plaintext. One bit and one block.

<h3>What are encryption and decryption?</h3>
  • The process of encryption converts plain text data (plaintext) into something that would seem random and meaningless (ciphertext). Decryption is the process of converting ciphertext to plaintext.
  • Encryption is the process of transforming information it in to a secret code that hides its true intent. The study of information encryption and decryption is known as cryptography. Ciphertext and plaintext are terms used to describe different types of data in the computer world.
  • Data is encrypted so that only those with the secret key (formally referred to as a decryption key) or password may decipher it in its new form, or code.
