This is awesome! A simple yet very useful tool, especially in environments where privacy and security are crucial for sharing addresses and sensitive information. I really like that the encryption happens client-side, which significantly enhances security.

Do you have any plans to open-source this project, or are you looking to develop it further based on feedback? Also, is there a mechanism to ensure that links can't be reused after being accessed once?

Either way, great work—I’ll definitely give it a try!
