Which of the following describes decryption?

Decryption is accurately described as the technique used to understand encrypted data. This process involves converting unintelligible, scrambled information (ciphertext) back into its original, readable format (plaintext). When data is encrypted, it is transformed using an algorithm and a key, making it secure against unauthorized access. Decryption reverses this process, allowing authorized users who possess the correct key to access and interpret the data.

Understanding this concept is crucial in cybersecurity, as effective encryption and decryption practices are essential for maintaining data confidentiality and integrity. This ensures that sensitive information remains secure during storage and transmission, and that it can be accessed by legitimate users when necessary.
