PKI Digital Signature

PKI is a system that uses two keys: public key known to everyone and a private key: that the key owner has full control of and must be kept in secure environment. 

A unique component to the PKI system is the connection between the public key and the private key – where the only public key can be used to encrypt messages and only corresponding private key can decrypt them.

PKI’s secure communication method allows only the sender and the intended recipient of the document to access its content.
