Study Notes
Encryption Basics
- The internet is not a closed and private system.
- Encryption is the process of scrambling a message, not unscrambling it.
Symmetric Encryption
- Symmetric encryption requires two people to agree on a secret key ahead of time: True
Public Key Cryptography
- Public key cryptography is the foundation of all secure messaging on the open internet: True
Encryption Keys
- Using 10-digit encryption, there could be 10 billion possible key solutions.
- Today's secure communications are encrypted using 256-bit keys.
Cracking Encryption
- A message is considered 'too hard' to crack when it is computationally infeasible to break the encryption.
- It would take an average computer today an extremely long time to try all 10 billion possibilities of a 10-digit encryption, making it impractical to crack.
