Paso 3. Inicia sesión en la app de la VPN. What is the function of the Hashed Message Authentication Code (HMAC) algorithm in setting up an IPsec VPN? guarantees message integrity authenticates the IPsec peers protects IPsec keys during session negotiation creates a secure channel for key negotiation Answers Explanation & Hints: The IPsec framework uses various protocols and algorithms to provide data confidentiality, data HMAC-SHA2-512-256; La propuesta de Cloud VPN presenta los algoritmos HMAC en el orden que se muestra. Cloud VPN acepta cualquier propuesta que incluya uno o más de estos algoritmos, en cualquier orden. Es posible que en la documentación de la puerta de enlace de VPN local se use un nombre un poco diferente para el algoritmo. The issue occurs when the VPN peers use two different IPsec proposals with one peer using hmac-sha-256-96 and the other peer using hmac-sha-256-128. Both these proposals use different encryption lengths. Solution: To avoid this issue, confirm that both VPN peers are using the same IKE/IPsec proposal settings.

Either disable the tls-auth option in your server config. The config line will look like In other words, HMAC SHA-1 as used by OpenVPN is considered secure and there is Mathematical proof of this. Of course, HMAC SHA-2 and HMAC SHA-3 are even more secure! Indeed, the recent OpenVPN audit recognizes that HMAC SHA-1 is secure, but recommends transitioning to HMAC SHA-2 or HMAC SHA-3 instead. VPN providers usually use the SHA-2 (Secure Hash Algorithm 2) cipher for HMAC authentication since it supports 224-bit, 256-bit, 384-bit, and 512-bit hash values, making it far more secure than SHA-1.
