Ensuring Authenticity: ForestVPN’s Robust Security Measures

Published Categorized as News

Verifying the authenticity of server connections is paramount. ForestVPN takes the lead in providing top-notch security, safeguarding users against potential threats like man-in-the-middle attacks. Let’s delve into the meticulous process ForestVPN employs to confirm the legitimacy of its servers.

Certificate Exchange: Unveiling the Key Information

When ForestVPN users connect to an OpenVPN server through the app, a crucial step unfolds—server identification through a certificate exchange. This certificate comprises three vital components:

  1. Cryptographically Secure Signatures
    • The certificate’s signature, computed using the private key of the ForestVPN Certificate Authority (CA), ensures the integrity of the connection.
    • ForestVPN’s CA employs a robust 4096 bit RSA key, surpassing the security standards of many popular websites.
  2. Unique Server Identification
    • ForestVPN app verifies the common name embedded in the certificate, ensuring it matches the expected server name.
    • An unexpected common name prompts the app to terminate the connection, maintaining a vigilant stance against potential threats.
  3. Server’s Public Key for Encryption
    • After confirming the server’s identity, ForestVPN establishes a secure and encrypted channel using the server’s public key.
    • Standard cryptographic techniques are employed to produce a symmetric key pair, ensuring a robust and private connection.

Unparalleled Certificate Security

ForestVPN stands out in certificate security compared to mainstream browsers. While browsers rely on a multitude of potentially variable certificate authorities, ForestVPN employs a single, unchangeable CA shipped with the application. Additionally, ForestVPN’s certificates boast SHA512 hashing and a 4096 bit RSA key, setting a higher standard for security.

Verifying ForestVPN’s Encryption

To validate ForestVPN’s encryption, follow these steps:

  1. Log in and download a ForestVPN config from the setup page.
  2. Extract the Certificate Authority from inside the tags and save it to a file.
  3. Run the following command from a shell: openssl x509 -text -noout -in $SAVED_FILE.

Confirming the Common Name

ForestVPN’s meticulous approach includes verifying the common name of the server. When connected, check the OpenVPN output for a line containing VERIFY X509NAME OK to confirm the common name.

ForestVPN’s Multi-Layered Security

Connecting to a ForestVPN server ensures a multi-layered security approach, including:

  • Best-in-class encryption
  • Uniquely identifiable VPN servers
  • A single trusted CA with a privately inaccessible key

This comprehensive strategy guarantees that your connections remain private and secure with ForestVPN.
