HCLTech SOC Analyst Interview Questions and Answers for Experienced

Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses different keys.

• Symmetric encryption is faster and more efficient than asymmetric encryption.

• Examples of symmetric encryption algorithms include AES and DES.

• Asymmetric encryption is more secure as it uses a public key for encryption and a private key for decryption.

• Examples of asymmetric encryption algorithms incl
