decryption

Decryption is the process of converting ciphertext, or scrambled information, back into its original, understandable form, known as plaintext. This is the inverse operation of encryption, which is the process of disguising information to make it unintelligible to unauthorized individuals.12

Key Concepts:
* Plaintext: The original, readable information.1
* Ciphertext: The disguised, unreadable information.12
* Key: A secret piece of information used to control the encryption and decryption process.12
* Algorithm: A set of procedures or instructions used in encryption and decryption.2

Codes and ciphers are often confused. A code replaces information with something else, like Morse code replacing letters with dots and dashes. A cipher, however, uses a secret key to transform plaintext into ciphertext, making it unreadable without the key.1

Decryption is crucial for secure communication, allowing intended recipients to access messages while keeping them secret from eavesdroppers.1345
