• An async/.await SOCKS5 implementation.
• An async/.await SOCKS4 Client implementation.
• An async/.await SOCKS4a Client implementation.
• No unsafe code
• Built on-top of tokio library
• Ultra lightweight and scalable
• No system dependencies
• Cross-platform
• Authentication methods:
  • No-Auth method
  • Username/Password auth method
  • Custom auth methods can be implemented via the Authentication Trait
• All SOCKS5 RFC errors (replies) should be mapped
• AsyncRead + AsyncWrite traits are implemented on Socks5Stream & Socks5Socket
• IPv4, IPv6, and Domains types are supported
• Config helper for Socks5Server
• Helpers to run a Socks5Server à la "std's TcpStream" via incoming.next().await
• Examples come with real cases commands scenarios
• Can disable DNS resolving
• Can skip the authentication/handshake process, which will directly handle command's request (useful to save useless round-trips in a current authenticated environment)
• Can disable command execution (useful if you just want to forward the request to a different server)

Open in crates.io.

Please check examples directory.

# Run client
RUST_LOG=debug cargo run --example client -- --socks-server 127.0.0.1:1337 --username admin --password password -a perdu.com -p 80

# Run server
RUST_LOG=debug cargo run --example server -- --listen-addr 127.0.0.1:1337 password -u admin -p password

# Test it with cURL
curl -v --proxy socks5://admin:[email protected]:1337 https://ipapi.co/json/

• Tests have to be implemented
• Better Rust doc
• UDP bind command not implemented
