This ensures that only the recipient can read the original message.Īlthough there are mathematical connections between the public key and the private key, doing so computationally is not practical. Decryption: In this step, the recipient uses their private key to decrypt the message, which was encrypted using their public key.This ensures that only the recipient, who has the corresponding private key, can decrypt and read the message.

Encryption: In this step, the sender uses the recipient’s public key to encrypt the message.The public key is made freely available to anyone who wants to send a message to the user, while the private key is kept secret by the user. Key Generation: In this step, a user generates a public-private key pair.The decryption process on the receiver’s end uses the decryption algorithm and the receiver’s private key to recover the original plain text message.Īsymmetric encryption typically consists of three main components: The recipient then receives this cipher via a transmission or communication channel. The encryption algorithm receives the sender’s plain text message, encrypts it using the recipient’s public key, and generates a cipher. The private key, on the other hand, is kept private i.e., only the receiver knows it and is used to decode data.īoth, the public key and the private key should be available at both the sender’s end and the receiver’s end for the asymmetric encryption to succeed. The public key, which is extensively used to encrypt data and is known to all, is one type of key. In this article you will learn about asymmetric encryption and the RSA algorithm.Īlso read: A* Algorithm – Introduction to The Algorithm (With Python Implementation)Īsymmetric encryption, commonly referred to as public-key cryptography, uses two distinct keys for encryption and decryption. Banking, email, e-commerce, and other industries all employ cryptography extensively. It includes a variety of techniques for converting plaintext into ciphertext, enabling secure communication, and protecting the confidentiality and integrity of data. Cryptography is the practice of securing communication by using codes and ciphers.
