When we talk about encrypted communication, we have to keep in mind two parties primarily; the sender and the receiver. The former encrypts and the latter decrypts. Described as the foundation of Public Key Infrastructure (PKI), Asymmetric Encryption key provides two keys, one is private and the other is public (which derives another name for it; public-key cryptography) and as a pair, the keys are called Public and private key pair. When a text is decrypted it is plaintext and when it goes through the process of decryption, it is called cyphertext.

The functionality of keys is sometimes interchangeable if one key has been used to encrypt the text, only the other key of the pair will be able to decrypt it. The use of these keys can also ensure a one-way communication channel in which public key holders can leave messages, reports, and entries which can only be decrypted and read by the person who possesses the private key.

The public key is distributed over the internet freely as it can only be used for sending the message s but a level of security is needed to keep secure your private key. The communication can be also of privatized by using the key of the recipient, in that case, no one else will be able to decrypt the message instead of the intended recipient.

The asymmetric key is the latest form of encryption cryptography compared to the Symmetric encryption. But both of these Encryption methods are used in Transport Layer Security and Secure Socket Layer (TLS/SSL) Protocol and the reason is more practical than we think. While the symmetric encryption works on a higher speed, the asymmetric encryption provides better security and privacy for your messages. In the process called TLS/SSL Handshake, the Asymmetric Encryption initiates the actions by establishing a safe and secure communication channel between the sender and receiver that is authorized.

Once the communication has been secured, the symmetric encryption takes over the process to provide the service at a better speed. Other protocols that use Asymmetric Encryption are Secure Shell (SSH) and OpenPGP. Your web browser also processes through TLS/SSL in order to get you to the website you want to visit. Not only the Asymmetric Encryption helps in protection against the cyber crimes it also ensures that your privacy is not breached by those you trust. It is one of the most effective methods.
