At four times the computation, which is a pretty big problem when you’re trying to authenticate every packet on a >= 10 Gb/s network Using a better hash like B

Using a better hash like Blake2 makes a lot more sense
- fiddlerwoaroof 6y agoIf the point of using two hashes is resistance against people breaking one of the hashing algorithms used, you’re always going to have to pick more than one algorithm to get that benefit. However, I don’t think nesting the calculations is actually necessary: Blake2(msg)+sha512(msg) would give you the same protection.
