VPN Encryption

The data you send and receive over the Internet, shouldn't it be all private? We think it should, however, the reality is such that any third party can find, access and even make use of your digital data.

To ensure the privacy and security of your data, top-notch encryption is a must. Cargo VPN strives to provide you with the safest access to the open Internet. This is why this VPN service offers super secure AES-128 and AES-256 encryption algorithms to effectively protect your personal data.

What is encryption?

Encryption is the process of converting data or information into a code that only authorized parties can decipher and access. The main point of encryption is to protect the confidentiality of data either stored on a device or transferred through a network, either local or Internet.

Encryption algorithms act like a barrier between your sensitive information and everyone else, making sure the data is safe from any unauthorized access. Encryption algorithms take the data and transport it through a secure "tunnel" where everything is scrambled and becomes gibberish until a decryption key is applied to get everything back to the way it was. Without a decryption key the data stays a complete nonsense to someone trying to get in possession of it.

Is Cargo VPN encryption secure?

The team behind Cargo VPN service scrupulously evaluates possible threats in order to offer the strong and most relevant data protection. We offer the most secure 128-bit and 256-bit encryption algorithms, depending on the protocol and operating system. Both these encryption types are military level and are intended for the top-level protection from brute-force attacks.


Cargo VPN offers various protocols that have their unique strengths and features. Depending on which protocols your device supports, which of them your network allows, and what gives you enough freedom and security, you can apply what's best for your data.

By default, Cargo VPN will apply the most optimal protocol for your network, but it offers flexible settings where you can configure the protocol that you want to be used.


Cargo VPN uses RSA as an authentication method. RSA is a secure authentication form that is independent from the network, router, domain name servers, or a computer. The only thing it relies on is a private key, which works in such way that even though it may be published online with anyone being able to send a message to the publisher, only the publisher will know how to read it properly.

Cryptographic handshake

Cargo VPN uses a Diffie-Hellman (DH) method with a minimum 4096-bit key, and Elliptic curve Diffie-Hellman (ECDHE) protocol with 256 bits. In this instance such connection is highly secure, because in cryptographic handshake the longer the key, the more secure your connection is.

Such type of encryption is extremely hard to hack, thanks to the fact the the key establishment happens independently of the server’s private key.

So, in a rather unlikely situation that your private key was somehow exposed, this algorithm protects your personal data from being decrypted.

Cargo VPN fights for your privacy

Cargo VPN is a highly efficient method to protect your personal information and communications when you are travelling, browsing online space, connecting to a public hotspot, or simply being concerned about over-the-top surveillance and data theft.
