Symmetric encryption uses the same secret key for both encryption and decryption, whereas asymmetric encryption uses a mathematically related public-private key pair. Symmetric encryption uses two distinct mathematical keys, whereas asymmetric encryption relies on a single shared secret passphrase. Symmetric algorithms like RSA are exclusively used for bulk data encryption, while asymmetric algorithms like AES are used for key exchange. Symmetric encryption provides non-repudiation natively without certificates, whereas asymmetric encryption cannot verify sender identity.
