What is a key pair and why is it required?
A key pair is a set of two uniquely linked cryptographic keys—a public key and a private key—used to secure data and control access.
It is a core component of asymmetric cryptography. The public key can be shared openly with anyone, while the private key must be kept strictly secret by the owner.
A key pair is required to achieve two fundamental security goals: secure identity verification and data privacy.
