Understanding VPN Encryption: Symmetric vs. Asymmetric 🔐

o There are two types of encryption keys symmetric and asymmetric encryption.
o Symmetric encryption uses a single key that needs to be shared among the people.
o Asymmetric encryption uses pair of public key & private key to encrypt and decrypt.
o Symmetric encryption is old technique while asymmetric encryption is relatively new.
o Asymmetric encryption takes relatively more time than the symmetric encryption.
o Symmetric key cryptography utilizes less resource as compared to Asymmetric key.
o Asymmetric key cryptography utilizes more resource as compared to symmetric key.
o An Asymmetric key is slower than symmetric key cryptography.
o A Symmetric key is faster than asymmetric key cryptography.
