Yes, KMS supports both symmetric and asymmetric encryption. Symmetric encryption uses a single key for both encryption and decryption processes, making it efficient for encrypting large amounts of data. Asymmetric encryption, on the other hand, uses a pair of keys: a public key for encryption and a private key for decryption. KMS manages both types of encryption by providing mechanisms to generate, store, and utilize these keys securely. This versatility allows KMS to be applicable for a wide range of security needs and encryption scenarios.
