What are the three (3) types of modern encryption?1 pointCiphertext HashSymmetricAsymmetric

The three types of modern encryption are:

1. Symmetric Encryption: This is the simplest kind of encryption that involves only one key that is used for both encryption and decryption. The sender uses this key to encrypt the plaintext and send the ciphertext to the receiver. On the other side, the receiver applies the same key to decrypt the message and recover the plaintext.

2. Asymmetric Encryption: This type of encryption uses two keys, one for encryption and the other for decryption. The key used for encryption is public and the key used for decryption is kept secret (private). If you encrypt something with the public key, only the private key can decrypt it and vice versa.

3. Hashing: While not technically encryption, hashing does transform plaintext in a way that is hard to reverse, which accomplishes much the same purpose. It takes a message of any length and returns a fixed length code. Unlike symmetric and asymmetric encryption, it's a one-way function. In other words, it's impossible to revert back to the original message if you know the hash value.
