collision resistance - Why is HMAC-SHA1 still considered

Understanding Googles SHA-1 Collision and OpenVPN HMAC-SHA1. I have had a couple of people email me with grave concern over the settings that our network uses for our VPN, referring to the Google (and Dutch) research project that created a SHA-1 collision on two documents.. There are a lot of things to unpack here, and we need to understand the underlying mechanics of what is going on before What Is OpenVPN & How Does OpenVPN Work? | CactusVPN Feb 01, 2019 networking - Setting up openvpn with a killswitch in a I'm trying to setup a kill switch so that if OpenVPN becomes inactive all other connections will be blocked. I tried to adapt this Linux set up, but it doesn't seem to work on FreeBSD. Using 160 bit message hash 'SHA1' for HMAC authentication Mon Jul 20 22:13:17 2020 TCP/UDP: Preserving recently used remote address: [AF_INET]184.75.221.34

OpenVPN is open-source commercial software that implements virtual private network (VPN) techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls.

Some more info, hope it helps: i to had this problem with hmac authentication in build r19215. after trying several modifications to my config files, collision resistance - Why is HMAC-SHA1 still considered A much deeper break of SHA-1's round function would be needed to break HMAC. Not coincidentally, M. Bellare's New Proofs for NMAC and HMAC: Security without Collision-Resistance shows that security of HMAC holds assuming only weaker properties on its round function than needed for collision resistance of the corresponding hash.
