Hash IDs for Open Spaces

[nicovillamonte]

Implement hashed IDs for OpenSpaces to prevent users from accessing other spaces by guessing the URL, ensuring a more secure experience.

For example:

from:

smart-open-space.com/os/3

to:

smart-open-space.com/os/e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

The second option is significantly harder to guess, ensuring a more secure user experience.
