git's hash algorithm is sha1dc, it is not sha1. Per Linus: > Honestly, git has effectively already moved from SHA1 to SHA1DC. > > So the actual known attack and weakness of SHA1 should simply not be > part of the discussion for the next hash. You can basically say "we're > _already_ on the second hash, we just picked one that was so > compatible with SHA1 that nobody even really noticed. Warn users who try to compile with SHA1 instead of SHA1DC.
