What type of encryption uses different keys to encrypt and decrypt the message?
+Secure
+Asymmetric
+Private key
+Symmetric - ✔✔Asymmetric
Asymmetric cryptography, also known as public key cryptography, uses public and

,+Caesar Cipher
+Vigenere
+RSA
+DES - ✔✔RSA
The RSA encryption algorithm is one of the most widely used public key encryption
algorithms that have ever been invented. It was created by the three scientists Ronald
Rivest, Adi Shamir, and Leonard Adleman in 1977, and today it is increasingly being
used in the network area.
Original, unencrypted information is referred to as ____.
+text
+plaintext
+cleantext
+ciphertext - ✔✔Plaintext

, Plaintext is a term used in cryptography that refers to a message before encryption or
after decryption. That is, it is a message in a form that is easily readable by humans.
Encryption is the process of obscuring messages to make them unreadable in the
absence special knowledge
Which of the following is not an asymmetric system?
+SSL
+DES
+PGP
+RSA - ✔✔DES
The Data Encryption Standard is a symmetric-key algorithm for the encryption of
electronic data. Although now considered insecure, it was highly influential in the
advancement of modern cryptography.
In order for User A to send User B an encrypted message that only User B can read,
User A must encrypt message with which of the following keys?
+User B's public key
