What is the difference between symmetric and asymmetric encryption, and when would you use each type in a cybersecurity context?

Difference between Symmetric and Asymmetric Encryption in Cybersecurity

Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses a pair of public and private keys for these purposes.

When to use Symmetric Encryption in Cybersecurity:

Symmetric encryption is faster and more efficient for encrypting and decrypting large amounts of data. It is commonly used for secure communication between two parties who already have the shared key, such as in VPNs or encrypting files locally.

When to use Asymmetric Encryption in Cybersecurity:

Asymmetric encryption is preferred for securing communication between parties who don't have a shared key initially. It ensures secure key exchange and authentication, commonly used in SSL/TLS for secure web browsing, digital signatures, and secure email communication.

Understanding the differences between symmetric and asymmetric encryption is crucial in implementing effective cybersecurity measures to protect sensitive information and communication.
