Key generation is the process of creating cryptographic keys used in various security protocols. These keys are essential for encrypting and decrypting data, ensuring that only authorized users can access sensitive information. The strength of the key directly impacts the security of the system, making it crucial to use robust algorithms and sufficient key lengths. There are different methods for key generation, including symmetric and asymmetric techniques. In symmetric key generation, the same key is used for both encryption and decryption, while in asymmetric key generation, a pair of keys—a public key and a private key—is created. This ensures secure communication and data protection.
