Symmetric = same key for encrypt and decrypt.
Asymmetric = different keys (public key for encryption, private key for decryption).
Asymmetric allows drug dealers to publish an encryption key that enables their clients to encrypt their address but it can only be decrypted by the private key that only the dealer has so if the encrypted address is intercepted by the market platform, hackers, or feds, they can't use the published key to decrypt it. It relies on things like prime factorization, which quantum computers are supposed to be good at. Dealers are starting to move over to elliptic curve methods that quantum is no good at.
