Question Explain the two common forms of encryption.
Answer
Two common encryption techniques are one-key encryption and two-key encryption.
One-key Encryption
The data is encrypted, and a key is provided with it to decrypt the data. Here, both the sender and receiver must know the key, which is common for both the sender and receiver. The receiver cannot decrypt the data without the key.
Two-key Encryption
It is otherwise called asymmetric encryption. It uses two keys, a known public key. The public key is used to encrypt the data, and the private key is used to decrypt the data.
