来源: feat: add Snell v5 protocol support by winmin · Pull Request #2816 · MetaCubeX/mihomo · GitHub

Summary

Add Snell v5 protocol support with the following implementation details:

  • AES-128-GCM AEAD with Argon2id KDF (t=3, m=8KiB, p=1)
  • 16-byte salt per direction, independent key derivation
  • 7-byte frame header: [type, reserved(2), padding_len(2 BE), payload_len(2 BE)]
  • Padding with byte interleave swap obfuscation
  • Lazy CONNECT response (server replies after first relay data)
  • Status byte + initial relay data merged in first response frame

Files changed

  • transport/snell/v5.go — v5 protocol implementation (new file)
  • adapter/outbound/snell.go — v5 adapter integration
  • transport/snell/snell.go — Version5 constant

Config example

- name: my-snell-v5
  type: snell
  server: example.com
  port: 15398
  psk: your_psk
  version: 5

个人点评:

Snell v5 协议是 surge 专属的闭源协议，谁给逆向了
