The security parameters configured for VyprVPN's OpenVPN 256 connections are as follows:
- Authentication: SHA256 (also known as SHA2)
- Control channel: AES-256-GCM cipher and SHA384 HMAC are the defaults. We can also use AES-256-CBC cipher/SHA256 HMAC, or AES-256-CBC cipher/SHA1 HMAC in the case that the client or network has compatibility issues with the default levels of encryption.
- RSA Encryption: TLS-ECDHE-RSA-2048. The ECDHE means we provide the "Elliptic curve Diffie-Hellman" key exchange, which provides Perfect Forward Secrecy.
Note that our OpenVPN 160 configurations, which are meant to provide a lower security protocol option in favor of potentially improved performance or resource usage, utilize Blowfish cipher, which is considered less secure.
