Protect the ones that do, and you can rest easy. And if you want a faster, easier solution, a full disk encryption is a good ideaâespecially on laptops that can get easily lost; the full disk encryption will protect all your data and ensure no one can break into your Windows computer or your Mac.
Modern cryptography is heavily based on mathematical theory and computer science practice; cryptographic algorithms are designed around computational hardness assumptions, making such algorithms hard to break in practice by any adversary.symmetric systems use public key to encrypt a message and a private key to decrypt it. Use of asymmetric systems enhances the security of communication. In colloquial use, the term  code  is often used to mean any method of encryption or concealment of meaning.
