What is the purpose of key exchange?

Cryptography is a fundamental aspect of modern communication, ensuring the privacy and integrity of data exchanged between parties. A crucial element of this process is key exchange, which involves the secure transfer of cryptographic keys between two entities.

These cryptographic keys act as the backbone of encrypted communication, enabling the parties to encrypt and decrypt information using a predefined cryptographic algorithm. The key exchange process ensures that only authorized parties have access to the keys, maintaining the confidentiality of the communication.

In a key exchange, the two parties negotiate and agree upon a set of keys that will be used for subsequent communication. This negotiation is typically done in a secure manner to prevent eavesdropping or tampering by unauthorized parties.

Once the keys have been exchanged, the parties can use them to encrypt and decrypt messages, ensuring that only the intended recipient can understand the content. This process is essential for maintaining the confidentiality of sensitive information, such as financial transactions or personal data.
