问题 Before I get too much into the details, the high level thing I'm trying to accomplish is encrypting some data in JavaScript, sending that to a web server, then decrypting that encrypted data in C#. The part I'm having trouble with is decrypting the data in C#. I'm encrypting some data in JavaScript like this (I removed the extraneous code): // https://github.com/diafygi/webcrypto-examples#rsa-oaep---encrypt window.crypto.subtle.encrypt( { name: "RSA-OAEP" }, publicKey, data ) .then(function

问题 Implementing something based on a pathetic documentation without no info nothing. The example is just this (7F02AAF7)H => (F7AA027F)H = -139853185 Let's say even if I convert 7F02AAF7 to F7AA027F , then still the output via 'parseInt('F7AA027F', 16)' is different from what I am expecting. I did some google search and found this website http://www.scadacore.com/field-tools/programming-calculators/online-hex-converter/ Here when you input 7F02AAF7 then it is processed to wanted number under

问题 TL;DR: A website is served over HTTPS and needs to access a WebSockets server over an unencrypted channel (ws:// url). The browser doesn't like this. Encrypting the websocket is possible, but inconvenient - there is no trusted authority which could sign the certificate and thus it will be needed to manually install it for every client. I'd like to leave that as the last resort. The website must be served over HTTPS and cannot be downgraded to HTTP. Is there any other way to bypass this
