What are some common encryption techniques used in web APIs?

Common encryption techniques for web APIs include AES, RSA, and TLS. AES is widely used for symmetric encryption, while RSA is used for asymmetric encryption. TLS secures data in transit.

Can you explain how AES works?

AES, or Advanced Encryption Standard, is a symmetric encryption algorithm that uses the same key for both encryption and decryption. It operates on blocks of data and can use key sizes of 128, 192, or 256 bits.

What is the difference between symmetric and asymmetric encryption?

Symmetric encryption uses the same key for both encryption and decryption, making it faster but less secure for key distribution. Asymmetric encryption uses a pair of keys (public and private), enhancing security but being slower.

How does TLS ensure secure communication?

TLS, or Transport Layer Security, ensures secure communication by encrypting data in transit, authenticating the parties involved, and ensuring data integrity through checksums.
