Study Notes

Encryption

Encryption disguises messages, only understandable by specific people.
A key explains how the message was disguised.
Encrypted data is called ciphertext, and plain text is unencrypted data.
Most modern communication relies on encryption.
Encryption is essential in applications for:
- Securely exchanging data between web servers and browsers
- Securing online transactions like money withdrawals.
- Sending secure emails.
- Sharing files, photos, and videos safely online.
- Protecting messaging conversations.
Encryption protects data while it's stored or sent. It doesn't prevent someone from reading a message but stops them from understanding it.
