Each of the two keys is kept hidden in public-key cryptography. 5: The personal key is symmetric since only one key is known as a private key. Asymmetric is the public key, so two types of keys exist: private and public. 6: The sender and receiver will use the same key in this encryption. op blocks prisonModern 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).
