What process reverses encryption to reveal the original plaintext?

Explanation:
Decryption is the process that reverses encryption to reveal the original plaintext. Encryption transforms readable data into scrambled ciphertext to protect it, and decryption performs the reverse operation, turning that ciphertext back into readable text using the appropriate key. A cipher is the method used to perform these steps, while a bit is just a single binary digit and isn’t a process.
