Cryptography gives me peace of mind in today’s digital world. It’s not just about hiding information it’s about making sure only the right people can access what matters, like my personal details or financial info. I rely on cryptography every time I send an email, shop online, or store files in the cloud. I also appreciate how digital signatures help me trust that documents and messages are authentic and haven’t been tampered with. Knowing these protections are in place makes me feel safer as I navigate both personal and professional digital spaces.
