// Let's do a threat model for this, since this goes against the standard advice of "never emed
// secrets in source code". This the sha256 hash of a 32 byte random password. So to crack it
// you'd have to calculate 2^256 sha256 hashses. Good luck. And then, if you do crack it,
// what is exposed? That function is used just to add basic auth to the internal stats
// endpoint for the server. Hishtory is designed so the server has access to zero sensitive
// data, so there is nothing sensitive to be concerned with. This endpoint just expoes basic usage
// information for my own curiousity. So an attacker getting access to it wouldn't matter.
// This the sha256 hash of a 32 byte random password. This is used to add basic auth to
// the usage-stats endpoint that allows me to view data on the current users of hiSHtory.
// Note that the backend never has access to any sensitive data, it only can view encrypted
// data. So all that this protects is metadata about interactions with hiSHtory. Cracking
// this hash would not allow access to history entries. If you have any complaints about
// this, please route them to /dev/null.
