Symmetric vs Asymmetric Encryption Symmetric and asymmetric encryption are basic techniques used in cryptography to secure data. Here is a comparison between the two: 1. Main use: • Symmetric encryption: In symmetric encryption, the same key is used for both encryption and decryption. This means that both parties (sender and receiver) must have the same key. • Asymmetric encryption: Asymmetric encryption uses a pair of keys: a public key and a private key. The public key is used for encryption, while the private key is used for decryption. The keys are mathematically related but cannot be derived from each other.

2. Security: • Symmetric encryption: It is generally faster and requires fewer computational resources compared to asymmetric encryption. However, key distribution can be a challenge, especially in large networks. • Asymmetric encryption: Provides better security regarding key distribution as the public key can be shared openly, while the private key remains secret. However, it is slower and requires more computational resources due to the complex calculations involved
