What is the reverse process of encryption used to decode secured data?

• A. Decryption
• B. Encryption
• C. Hashing
• D. Encoding

Answer: (A)

Reversing encryption means turning ciphertext back into the original message. This is decryption, which uses the appropriate key (same key in symmetric systems or the matching private key in asymmetric systems) to recover the plaintext. Encryption hides data by transforming it into unreadable form, while decryption restores readability by applying the correct key. Hashing is one-way and cannot be reversed, encoding is just data formatting, and the forward encryption step is not the reversal. So the reverse process of encryption used to decode secured data is decryption.
