WebThus, TLS starts with asymmetric encryption (with two keys) and moves to symmetric encryption (with one key). Both sides use the same keys during the communication session, but when they start a new session, they will … Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can decrypt this d…
