V2Ray: VMess, VLESS, and Trojan Protocol Comparison

The modern digital era requires high data protection and privacy. In light of this, V2Ray is becoming a popular tool that offers a wide range of solutions for creating private networks. V2Ray is a powerful platform for creating private networks and ensuring online privacy. It was developed as part of the V project in 2015 and was originally intended as an alternative to Shadowsocks. V2Ray works with protocols such as VMess, VLESS, Trojan and others, making it a flexible tool for various scenarios. In this review, we will consider the key differences between these protocols and their possible applications.

V2Ray Main Protocols and Their Main Features

V2Ray supports several protocols that are used for secure data transfer and bypassing blocking:

• VMess is a TCP protocol designed for secure and anonymous data transfer. Main features: a wide range of encryption algorithms, including AES-128-GCM and AES-256-CBC; support for custom headers allows adding random data, making it more difficult to identify traffic; an asymmetric encryption system eliminates the need for traditional handshake methods (a handshake is a method by which a client and server exchange data to establish a secure connection), which increases the connection speed.
• VLESS is a newer protocol that appeared in 2020. It was designed to optimize resource usage. Key features: fast handshake by reducing data exchange between the client and server; high performance due to the use of ChaCha20-Poly1305 encryption, which is faster than AES-GCM; ideal for users who value speed and resource savings.
• Trojan is a protocol that disguises traffic as regular HTTPS, making it difficult to detect. It offers the following features: encryption using TLS makes traffic virtually indistinguishable from standard HTTPS requests; flexible port settings and WebSocket support allow it to be used in most modern browsers; protection from active detection thanks to advanced traffic masking.

Technical differences:

• Encryption. VMess supports several encryption algorithms. VLESS more easily carries out the encryption process thanks to ChaCha20-Poly1305. Trojan reliably encrypts based on TLS.
• Traffic masking. All three protocols support obfuscation, but Trojan provides a better level of masking due to the use of standard HTTPS requests.
• Performance. VLESS and Trojan have high performance due to a simplified handshake process.

VMess, VLESS, and Trojan Usage Examples

Due to its flexibility and complex structure, VMess can use more system resources, which may not be suitable for weak or outdated devices. Optimal use of this protocol may require a deep understanding of network settings, which makes it difficult for novice users to configure. For users living in countries with high levels of Internet censorship (for example, China or Iran), VMess may be a better choice. Its flexibility and the ability to disguise traffic as standard HTTP requests allow you to successfully bypass blocking, providing access to blocked resources such as YouTube or Google.

Despite its high performance, VLESS has limited functionality compared to VMess, not supporting some features such as custom headers or advanced encryption methods. While VLESS is a fast protocol, its encryption is limited, which may be a drawback for users who require a more sophisticated data protection system. VLESS is ideal for those who use VPN on mobile devices, especially in conditions of limited Internet speed. For example, users who want to maintain a high level of security when connecting to public Wi-Fi in cafes or airports can choose VLESS for a more stable and faster connection.

Despite its high level of protection, Trojan is not as widely used as VMess or VLESS, which limits the number of applications and clients that support this protocol. Trojan requires more complex configuration and knowledge of network protocols, which can be a problem for regular users who do not have experience in setting up VPN connections. Trojan is often used by users who work in networks where strict censorship measures and deep packet inspection are active, for example, on corporate networks with an increased level of security. It can also be useful in countries with increased internet monitoring, such as Turkey or Russia, where VPN services are often blocked.

All three protocols - VMess, VLESS and Trojan - offer advanced capabilities for data protection and bypassing blocking. The choice of protocol depends on the user's priorities: flexibility, performance or protection from detection. VMess is suitable for those who value customization and security options, VLESS is better for low-power devices, and Trojan is for those who require maximum privacy.

Private VPN server in action

Using a private VPN server, especially with V2Ray support, significantly increases the level of security and flexibility of connections. When using a private VPN, you can configure support for all three protocols - VMess, VLESS and Trojan, which allows you to choose the best solution for each case, providing maximum protection and privacy.

If you value complete confidence in your digital security, the best solution is to buy a private VPN server on Private VPN server. Unlike standard services, everything here is customized to your individual needs, which minimizes the risks of surveillance and data leaks.
