Leadaxe：LxBox 不支持 happ 加密链接，并说明不跟进的理由与替代办法
对于为 LxBox 增加 happ://crypt* 支持的请求，作者答复不会加入，并说明原因：该链接是对订阅地址做的一层 RSA 加密块，解密需要 Happ 应用内置的私钥，而这把私钥之所以出现在应用之外，是因为有人把它提取了出来；每出现一个新格式版本（crypt4、crypt5 等）就意味着要再追一把新密钥，而所附 HTML 在 crypt3 就已止步。他称这是闭源客户端与外界之间的追密钥游戏，LxBox 不参与，也不愿在 GPL 项目里分发他人提取的私钥；并指出即便解密也不够——服务端通常还有 HWID 与 User-Agent 校验，除非客户端伪装成 Happ，否则解密出的地址依然不可用。他建议需要底层订阅的用户向服务商索取普通链接（服务商两种都能提供），只想解码已有链接的可使用他人维护的独立工具（hpwnr、happ-decrypt-universal、happ-decryptor），并声明这些与本项无关联。他还提到据他所知没有开源客户端支持这类链接，PassWall2、Hiddify 与 Throne 出于同样理由也拒绝过，议题以 not planned 关闭。
作者原文@LeadaxeThanks for the write-up and the attachment — I read both, plus Happ's crypto-link docs.
We are not going to add
happ://crypt*support to LxBox, and I'd rather say why than let it sit.The link is a plain RSA block over a subscription URL. Decrypting it needs Happ's private key, which is embedded in their app and only exists outside of it because people extract it. Each new format version (
crypt4,crypt5, …) means a new key to chase, and the attached HTML already stops atcrypt3. That's a key-chasing game between a closed client and everyone else, and LxBox is not going to play it: shipping someone else's extracted private key in a GPL app is not something I want in this repository. It wouldn't even be enough on its own — these links usually sit behind HWID and User-Agent checks on the provider side, so a decrypted URL still fails unless the client pretends to be Happ.If you need the underlying subscription, ask your provider for a regular link; providers can issue both. If you just want to decode a link you already have, standalone tools exist and are maintained by others, for example:
- https://github.com/Omegaplexx/hpwnr (Rust, up to crypt5)
- https://github.com/amurcanov/happ-decrypt-universal (Rust)
- https://github.com/LeeeeT/happ-decryptor (JS)
Use them at your own discretion — they are not affiliated with this project.
For the record, no open client I know of supports these links either (PassWall2, Hiddify and Throne declined for the same reasons). Closing as not planned.
