From 041e9235c1710936a43f73d2f6e87bfc6e1c2242 Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Thu, 13 Dec 2018 11:26:09 -0500 Subject: Lower the loop_max constant in curve25519_basepoint_spot_check() The point of this function is to make sure that the ed25519-based implementation of curve25519_basepoint() actually works when we start tor, and use the regular fallback implementation if it doesn't. But it accounts for 9% of our startup time in the case when we have directory information, and I think it's safe to make the test shorter. After all, it has yet to find any actual bugs in curved25519_scalarmult_basepoint_donna() on any platforms.
