AES-256 encryption

AES-256 encryption

AES-256 Encryption is a symmetric key algorithm. It uses block cipher encryption technology with a fixed-length block size. Its high safety and anti-attack solid capabilities make it widely used in many fields.



Obfuscation techniques involve activities such as disguising the protocol traffic to make it appear like other types of traffic or encrypting it in a way that makes it difficult to distinguish from random noise.

Frequently asked questions

Should I choose the Everest-SMTP protocol?

We would recommend you choose the 'Auto' protocol, but sure, you choose the Everest-SMTP protocol to try. If it connects fast and works well, it's a good choice for you. If Everest-SMTP doesn't work for you, X-VPN will automatically connect you to other protocols.

Why isn't my chosen protocol the one that successfully connects in the end?

X-VPN will attempt to connect using your chosen protocol as the first option. If the connection fails, X-VPN will automatically try other protocols until it finds one that successfully connects.

What's the difference between Everest-SMTP and SMTP?

SMTP is a network transport protocol, and Everest-SMTP is a proprietary protocol developed by X-VPN. It utilizes SMTP as the network transport protocol while also incorporating AES-256 encryption and obfuscation, thereby enhancing both security and bypassing capabilities.
