What is the main function of Asymmetric Encryption?

The primary function of asymmetric encryption is to facilitate secure key exchanges. In asymmetric encryption, two keys are used: a public key and a private key. The public key, which can be shared openly, allows individuals to encrypt messages intended for the key holder. The corresponding private key, kept secret by the owner, is used to decrypt those messages. This method not only ensures that data can be securely transmitted between parties but also authenticates the identity of the sender, as only the holder of the private key can decrypt the information.

While backing up data, formatting data, and cataloging electronic files are important tasks within information management, they do not inherently relate to the core principles of encryption. The main goal of asymmetric encryption is to establish a secure method for exchanging keys and data, making it crucial for secure communications in various digital environments.
