Select Three Examples of Cryptographs
What are three examples of cryptographs?
Answer:
The three examples of cryptographs are:
- Secret key
- Public key
- Hash functions
Explanation:
Secret Key: A secret key is also known as a symmetric key. It is a key that is used for both encryption and decryption processes. The same key is used to encode and decode the message, hence the term "symmetric." This type of key is commonly used in algorithms like Data Encryption Standard (DES), Advanced Encryption Standard (AES), and Triple Data Encryption Algorithm (3DES).
Public Key: A public key is used in asymmetric encryption. It is used to encrypt the data and can be shared publicly. However, the corresponding private key is required to decrypt the encrypted data. Public key cryptography is widely used in various protocols like Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Pretty Good Privacy (PGP).
Hash Functions: Hash functions are algorithms that take an input (or message) and produce a fixed-size string of bytes. The output, known as the hash value or hash code, is unique to the input data. Hash functions are commonly used in digital signatures, integrity checks, and password storage.
