    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]).

      As far as I understand, quantum computing can cut it in half, to 128 effective bits. Still way too large to brute force from there.
