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
I then rm openvpn.log thinking of restarting a fresh log. But openvpn.log didn't get created and I now can't find the logs. Where has the log gone to now?

This issue is very common for all OpenVPN users. While the general advice you can find on the Internet is to tweak the MTU […] Both SHA1 and SHA512 are hash functions. If you are using them as a cryptographic hash, then perhaps that is good reason to use SHA512; however, there are applications that use these function simply to identify objects. For example, Git uses SHA1 to cheaply distinguish between objects.
