Detailed explanation-1: -The difference in the length of the keys is so pronounced that a 2048-bit asymmetric key and a 128-bit symmetric key provide about an equivalent level of security. Asymmetric encryption is notably slower than symmetric encryption, which has a faster execution speed.
Detailed explanation-2: -One reason asymmetric encryption is often regarded as more secure than symmetric encryption is that asymmetric encryption, unlike its counterpart, does not require the exchange of the same encrypt-decrypt key between two or more parties.
Detailed explanation-3: -Digital Signing: Asymmetric encryption is much better for digital signing, compared to symmetric encryption. The use of both a public and private key means the identity of the signer of the data can easily be known.
Detailed explanation-4: -RSA (Rivest Shamir Adleman)-RSA is considered one of the most secure (and commonly used) asymmetric key encryption algorithms. It’s virtually uncrackable using modern computers.
Detailed explanation-5: -There is no shared key. A message encrypted with a key can not be decrypted with the same key.
