How does cryptography create confidentiality, integrity, trust, and authentication in modern systems?
Encryption hides data so only authorized users can read it.
Without the correct key, encrypted data is meaningless.
Hashing creates a fingerprint of data.
If even one character changes, the hash changes dramatically.
Certificates and keys verify that a user or system is legitimate.
Digital signatures prevent people from denying their actions.

Cryptography isn’t just “scrambling stuff.”
