    So Git, in version 3.0, is moving to SHA-256 by default for SHA-1 ain't considered that strong anymore but...

    What about future attacks by quantum computers? Is Git safe from quantum computers for it's all hashes only? Or shall there be issues with quantum attacks?

    I'm asking for there are several projects that are already moving to quantum-resistant schemes (like OpenSSH who uses an hybrid scheme [1]).

      At this point, it does not appear that (reasonably strong and modern) symmetric cryptography (ciphers, hash functions, etc.) is realistically threatened by quantum computing: <a href="https:&#x2F;&#x2F;words.filippo.io&#x2F;128-bits&#x2F;" rel="nofollow">https:&#x2F;&#x2F;words.filippo.io&#x2F;128-bits&#x2F;

        Good point here I had never thought about, but it&#x27;s still good to upgrade to 256 bits when possible for peace of mind.

        This has nothing to do with SHAttered
