The full certificate information is sent over the network by the server to the client as part of the SSL Handshake protocol. Before establishing a secure connection between a client and a server, the client needs to read the certificate information to make sure that it trusts the server. If you think about this, it isn’t too surprising. SSL Certificates over the networkĬontrary to popular belief, when traffic between servers is encrypted using TLS or SSL, the certificates themselves are actually not encrypted. There is only one place where all certificates look the same no matter in which format they are stored – the network. They can be encoded in Base64 or DER, they can be in various key stores such as JKS stores or the windows certificate store, or they can be encrypted files somewhere on your file system.

These certificates can come in many shapes and forms which can make finding them difficult. As more and more software today uses encryption, you have more and more certificates you need to keep track of. Managing SSL certificates on your network can be challenging. (Update! Faddom is releasing a free SSL Certificate Locator tool.
