Hey everyone,
I’m working on a project using web components with Lit. I’m curious about handling sensitive information in custom events, especially since they need to bubble up from the shadow DOM.
Here’s my main concern: Can other parts of the page, like browser extensions, intercept these events if they know the event name? I’m wondering if I should add an extra layer of security.
One idea I had was to encrypt the event payloads and keep the decryption key in a higher-order component. But I’m not sure if that’s overkill or even necessary.
Has anyone dealt with this before? What’s the best practice for keeping custom event data safe? Any advice would be awesome!
Thanks in advance for your help!
I’ve dealt with similar concerns in my projects. While encryption isn’t typically necessary for custom events, it’s good you’re thinking about security. In my experience, the key is to minimize sensitive data in client-side events altogether.
Instead, I’ve found success using unique identifiers or tokens in the events, then handling the sensitive operations server-side. This approach has worked well for me, balancing security and performance.
That said, if you absolutely must include sensitive data in your events, consider using a simple obfuscation technique rather than full encryption. It’s less resource-intensive and can still deter casual snoopers.
Remember, though, that any client-side solution isn’t foolproof. Always validate and sanitize data server-side, and use HTTPS for all communications. These practices have served me well in keeping my applications secure without overcomplicating the client-side code.
hey man, encryption for custom events sounds like overkill tbh. browser extensions can prob see that stuff anyway. maybe focus on securing server-side data instead? just my 2 cents. good luck with ur project!
Great question, John. While encryption for custom events isn’t typically necessary, it’s wise to consider security implications. Instead of encryption, focus on minimizing sensitive data in client-side events. Use server-side validation for critical operations and transmit sensitive information via secure channels (HTTPS). If you must include sensitive data in events, consider using one-time tokens or implementing a challenge-response mechanism. Remember, no client-side solution is foolproof against determined attackers with access to the browser environment. Always treat client-side data as potentially compromised and design your server-side logic accordingly.
