"Error: Unknown message digest" when using crypto.subtle.verify({'name':'ECDSA', 'hash':'SHA-256'}, ...)

从 webextension/content/tls.js 中第 634 行附近的 crypto.subtle.verify 调用开始，并将打包后的 bundle.js 路径与未打包的 pgsg-node.js 行为进行比较。使用 node bundle.js 和 qjs bundle.js 重现，然后跟踪 ECDSA SHA-256 验证如何到达 crypto-browserify。完成标准是：打包后的验证不再报告“Unknown message digest”，同时保留成功的密钥导入。

I'm trying to bundle the PageSigner pgsg-node.js (written in NodeJS) using browserify, such that I can run it via QuickJS and eventually compile it to WASM. (Not for a browser application however - I need to run it on a WASM VM).

After some necessary edits to the code of pgsg-node.js, I managed to successfully execute both node bundle.js and the QuickJS analogue qjs bundle.js and log the final output to the console. However, that only works if I remove this crucial line:

var result = await crypto.subtle.verify({'name':'ECDSA', 'hash':'SHA-256'}, notary_pk_CryptoKey, ba2ab(sig_p1363), ba2ab(signed_data_ba))

and replace it with var result = true. Otherwise I get the following error after executing node bundle.js:

What's weird is that at least some of the crypto.subtle functionality works, the line right before

var notary_pk_CryptoKey = await crypto.subtle.importKey(
      "raw", ba2ab(notaryPubkey_ba), {name: 'ECDSA', namedCurve:'P-256'}, true, ["verify"]);

works flawlessly. Also, executing my modified unbundled file node pgsg-node.js does not produce this error.
