A certificate authority is just one aspect of moving towards creating secure access within an organization. CA is the part of security which will generate digital certificates for individual users. Another part of CA creates both public and private keys to further enhance security. You can use both of these features of CA to implement electronic signatures for document signing or within email messages. You can even use CA to encrypt data while it is being transmitted from one user to another.
You Can Implement Your Own In-House Certificate Authority
Implementing your own certificate authority solutions is possible when you use the right types of applications, like we have, here at Digi-Sign. CA should be core to your public key infrastructure (PKI) and is used to issue digital certificates and electronic signatures. Distributing certificates is handled by the system administrator by sending the end user an email message to apply for the digital certificate.
