So doubling the number of bits to add that extra layer of protection brings one drawback – speed. The RSA-2048 bit key would take approximately 300 trillion years for an ordinary conventional computer to crack. ProtonVPN uses a 4096-bit version of the RSA (Rivest-Shamir-Adleman) encryption key, but the 2048-bit version is already secure enough. Hence, some consider the latter to be faster, although the differences in speed and complexity are minor. Both are very similar, but the main difference is that AES-256 divides data into blocks, whereas ChaCha20 ciphers each bit of data separately. Data encryptionĪlong with AES-256 encryption, Surfshark and ProtonVPN also use ChaCha20 encryption for the WireGuard protocol. Both providers offer the same VPN protocols, Kill Switch, and use robust AES-256 (Advanced Encryption Standard) encryption. Encryptionįrom VPN protocols to data encryption, you can see that most of the security features between Surfshark and ProtonVPN are similar. Also, both VPN providers ensure that your DNS requests will be handled by their private DNS so no one can access them in an unencrypted format.
They both offer WireGuard, OpenVPN, and IKEv2.
There is no crucial difference regarding VPN protocols and DNS (Domain Name System) status when comparing Surfshark and ProtonVPN.
