What is Private Key?

Public-key cryptography (asymmetric cryptography) is a specialized cryptographic system that utilizes pairs of lengthy alphanumeric keys that only function when used in tandem. Public keys represent a wallet address that can be distributed to others. Private keys are to be known only by their owner and grant access to funds. The generation of these keys is made possible by the usage of cryptographic algorithms based on mathematical problems to produce a one-way function.
