Qus : Which type of cryptography uses a single key for both encryption and decryption?
Qusकिस प्रकार की क्रिप्टोग्राफी एन्क्रिप्शन और डिक्रिप्शन दोनों के लिए एक ही कुंजी का उपयोग करती है?
A. Symmetric cryptography B. Asymmetric cryptography
C. Hash cryptography D. Quantum cryptography
Solution
A. Symmetric cryptography
Explanation
Symmetric cryptography, also known as secret-key cryptography, uses a single secret key for both encryption and decryption processes, making it faster and more efficient for large volumes of data.
