Which description best defines Data Decryption?

• A. Data Decryption
• B. Process of converting encrypted data back to original form
• C. Data Recovery
• D. Data Masking

Answer: (B)

Data decryption is the process of converting encrypted data back to its original form. When data is encrypted, it becomes unreadable to protect confidentiality; decryption uses the correct key and algorithm to restore it to plaintext so authorized users can access it. This distinguishes it from data recovery, which is about restoring lost or damaged data, and data masking, which hides sensitive values rather than reversing encryption.
