Which is the largest disadvantage of the symmetric encryption?

Which is the largest disadvantage of the symmetric Encryption? 1. More complex and therefore more time-consuming calculations. 2. Problem of the secure transmission of the Secret Key. 3. Less secure encryption function. 4. Isn't used any more. Answer 2 is correct.

Which is better, asymmetric or symmetric encryption?

Asymmetric encryption is the more secure one, while symmetric encryption is faster. They’re both very effective in different ways and, depending on the task at hand, either or both may be deployed alone or together. Only one key (symmetric key) is used, and the same key is used to encrypt and decrypt the message.

What are the types of symmetric encryption?

Types of symmetric encryption algorithms. Symmetric encryption algorithms are divided into two types by their operating principle: block ciphers; stream ciphers; Block algorithms encrypt data in fixed-length blocks (64, 128, or another number of bits, depending on the algorithm).

What does asymmetric cryptography mean?

What does asymmetric encryption mean? Asymmetric encryption, also known as public-key encryption, is a form of data encryption where the encryption key (also called the public key) and the corresponding decryption key (also called the private key) are different. Therefore, a recipient could distribute the public key widely.
