Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which three protocols use asymmetric key algorithms? (Choose three.)
A
Secure Sockets Layer (SSL)
B
Secure File Transfer Protocol (SFTP)
C
Pretty Good Privacy (PGP)
D
Advanced Encryption Standard (AES)
E
Secure Shell (SSH)
Explanation: 

Detailed explanation-1: -S/MIME. GPG, an implementation of OpenPGP, and an Internet Standard. EMV, EMV Certificate Authority. IPsec. PGP. ZRTP, a secure VoIP protocol. Transport Layer Security standardized by IETF and its predecessor Secure Socket Layer. SILC. More items

Detailed explanation-2: -Common asymmetric encryption algorithms are essential in secure communication and data transmission. Examples of these algorithms include RSA, Diffie-Hellman, and Elliptic Curve Cryptography (ECC).

Detailed explanation-3: -The two main uses of asymmetric-key algorithms are public-key encryption and digital signatures. Public-key encryption is a method where anyone can send an encrypted message within a trusted network of users.

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: -Rivest-Shamir-Adelman (RSA) Digital Signature Standard (DSS) Elliptic Curve Digital Signature Algorithm (ECDSA)
