Does a VPN use symmetric or asymmetric encryption?

PKI must use asymmetric encryption because it is managing the keys in many cases. This implies the use of public and private key pairs, which is asymmetric.


How many keys are utilized in asymmetric encryption?

Asymmetric encryption uses at least 2 keys - hence the asymmetry. The keys for encryption and decryption are not the same, so they are not "symmetric". Usually only 2 keys are used - a public key and a private key. The public key is published to a key registry or sent separately to those the key-pair owner wants to communicate with. The private key is retained by the owner. Messages encrypted with the private key can only be decrypted using the public key. If the source of the public key is trusted, this provides some proof of the source of the message. Messages encrypted with the public key can only be decrypted using the private key - so only the owner of the private key should be able to decrypt messages encrypted with their own private key.

How Asymmetric encryption normally how many keys are utilized?

Nearly all asymmetric encryption algorithms - and all the common ones, use 2 keys. Typically one key is held secret by the owner and is known as the "private key" while the other is published or distributed to the world and is known as the public key. Each key allows for decrypting something encrypted using the other key.


What is symmetric and asymmetric?

From another user: Symmetric cryptography uses the same secret (private) key to encrypt and decrypt its data whereas asymmetric uses both a public and private key. Symmetric requires that the secret key be known by the party encrypting the data and the party decrypting the data. Asymmetric allows for distribution of your public key to anyone with which they can encrypt the data they want to send securely and then it can only be decoded by the person having the private key. This eliminates the need of having to give someone the secret key (as with symmetric encryption) and risk having it compromised. The issue with asymmetric is that it is about 1000 times slower than symmetric encryption which makes it impractical when trying to encrypt large amounts of data. Also to get the same security strength as symmetric, asymmetric must use strong a stronger key than symmetric.


How many keys are used in triple encryption?

In 3DES, 3 distinct keys are used as K1, K2 and K3. First encrypt with K1, then Decrypt with K2 and finally Encrypt with K3 so actual key length used in 3DES is 168 excludin 8 bit party from each 64 bits means (56+56+56 becomes 168).
