If it is the locking key, then it can be used to send private communication. It requires 7 or more persons for its set up. These keys are created using RSA, DSA, ECC (Elliptic Curve Cryptography) algorithms. A private company is a closely held one and requires at least two or more persons, for its formation. On the other hand, asymmetric encryption uses two keys called public key and private key for encryption and decryption. The public key is also called asymmetric cryptography.
