When a certificate is signed by a trusted certificate authority, or validated by other means, someone holding that certificate can rely on the public key it contains to establish secure communications with another party, or validate documents digitally signed by the corresponding private key.

To do this, it first generates a key pairkeeping the private key secret and using it to sign the CSR.

The c509 of this party is to certififat to the identity of each party in the transaction sender and receiver by binding the pubic key of each party to a document known as a certificate that contains information such as the origination domain, and method used to generate the keys.
