## Password

Shadowsocks 2022 使用与 WireGuard 类似的预共享密钥作为密码。

使用 `openssl rand -base64 <长度>` 以生成与 shadowsocks-rust 兼容的密钥，长度取决于所使用的加密方法。

| 加密方法                          | 密钥长度 |
|-------------------------------|-----:|
| 2022-blake3-aes-128-gcm       |   16 |
| 2022-blake3-aes-256-gcm       |   32 |
| 2022-blake3-chacha20-poly1305 |   32 |

在 Go 实现中，32 位密钥始终工作。
