A simple and enough Shadowsocks Implementation.

I was create a small shadowsocks server weaknet-python at 2015.
I was always used it with stream crypto algorithm chacha20-ietf. I found that the newest windows client was drop all stream crypto algorithm when i was buy a new Windows laptop at 2021.
So, i need upgrade the server for my shadowsocks clients. I am unhappy.

• My principle is Simple and Enough
  I just need a server, i don't need others in the source code. I don't like split sub projects for one job.

• The library libevent is cute, so use c/c++

Depends on libevent openssl sodium.

cmake -DCMAKE_BUILD_TYPE=Release .

Usage: weaknet-server [options-file] [options]
Options:
 -p or --port <port>, range 1-65535
 -m or --algorithm <algorithm>, support list:
    chacha20, chacha20-ietf,
    chacha20-ietf-poly1305,
    xchacha20-ietf-poly1305
 -s or --password <password>
 -v or --version
 -h or --help

Support socks4 socks4a socks5 http-connect http-proxy protocol.

Usage: weaknet-client [options-file] [options]
Options:
 -p or --port <port>, range 1-65535
 -m or --algorithm <algorithm>, support list:
    chacha20, chacha20-ietf,
    chacha20-ietf-poly1305,
    xchacha20-ietf-poly1305
 -s or --password <password>
 -R or --remote-addr <ip:port>
 -v or --version
 -h or --help

Just a text file, useful for hiding options from the command line.

./weaknet-server ./server.conf -p 12345

server.conf example:

-m chacha20
-s 12345
