What are the 4 principles of cryptography?

Data Confidentiality, Data Integrity, Authentication and Non-repudiation are core principles of modern-day cryptography.

What are the 3 types of encryption keys?

Symmetric, or secret key encryption, uses a single key for both encryption and decryption. Symmetric key encryption is used for encrypting large amounts of data efficiently. 256-bit AES keys are symmetric keys. Asymmetric, or public/private encryption, uses a pair of keys.

What are two types of cryptography?

Cryptography is broadly classified into two categories: Symmetric key Cryptography and Asymmetric key Cryptography (popularly known as public key cryptography).
