Which process converts encrypted data back into its original form?

Which process converts encrypted data back into its original form?

• A. Decryption
• B. Encryption
• C. Cryptography
• D. Cipher Text

Answer: (A)

The essential idea is that cryptographic systems use two opposite operations to protect and recover data: encryption and decryption. Decryption is the process of converting ciphertext back into the original plaintext using the appropriate key. This is precisely how a message recovered by the recipient becomes readable again after it has been encrypted for secure transmission. Encryption, on the other hand, turns plaintext into ciphertext to hide content. Cryptography is the broader field covering these methods, and cipher text refers to the encrypted data produced by encryption. So the act that restores the original form is decryption.
