Write at least 1 byte. This ensures that sockets are ready to use for writing.
Windows specific: during the system startup, sockets can be created but the underlying buffers may not be setup yet. If this is the case Write fails with WSAENOBUFS: "An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

Not all URLs are extracted from the complicated csv file.
However, they do offer a txt file for the same list, which does work correctly with the current regex:
https://www.malwaredomainlist.com/forums/index.php?topic=3270.0
This url replacement pull request is easier than rewriting the entire regex (which then breaks other lists).
This works over DNSCrypt and DoH, but requires a specifically configured
server.
Instead of sending the actual DNS queries, the SH-T system works as follows:
Step 1: the client query is evaluated through Argon2id, a military-grade,
memory-hard, CPU-hard stretching function. This makes it very expensive
for an attacker to find the original query, even using GPUs and ASICs.
For post-quantum resistance, we use it to generate a 1024-bit key.
Step 2: in case the Argon2id algorithm has a vulnerability, or, since this
is a popular function used for hashing passwords and for cryptocurrencices,
and people may have built rainbow tables already, we use a hash function over
the result of the previous function. This immediately defeats rainbow tables.
Step 3: the output of the hash function is truncated to 64-bit.
Due to a property of this operation known as collision-misresistance, and even
if the previous steps fail due to a nation-state actor, it is impossible for a
server operator to prove what exact query was originally sent by a client.
This feature is experimental.
* 'master' of github.com:jedisct1/dnscrypt-proxy:
Re-add a big download link in addition to the badge
Fix Matrix badge and replace the latest release notice with a badge (#749)
Add Matrix Chat Badge (#747)
* The shiels.io page seems to generate wrong links (sorry for that!) I reported it to the shields.io project to fix this ASAP.
* Replaced the "latest release" notice information with a badge which automatically fetches the latest "Release" which means no one has to manually edit the readme each time a new release was introduced.
