What is a security key

A security key is a parameter that is entered into an algorithm that converts plaintext to ciphertext or ciphertext to plaintext. Keys are divided into symmetric keys and asymmetric keys. Data encrypted with the public key can only be decrypted by the private key, and data encrypted with the private key can only be decrypted by the public key.

Introduction to security keys:

The key is a parameter that is entered in the algorithm that converts plaintext into ciphertext or ciphertext into plaintext. Keys are divided into symmetric keys and asymmetric keys.

Data encrypted with the public key can only be decrypted by the private key. On the contrary, data encrypted with the private key can only be decrypted by the public key. It is this asymmetry that makes the public key cryptosystem So useful.
