Without a trusted signed certificate, your data may be encrypted, however, the party you are communicating with may not be whom you think. The certificate, signed by a trusted Certificate Authority (CA), ensures that the certificate holder is really who he claims to be. However, certificates do serve a crucial role in the communication process. Thus if a message or data stream were encrypted with the server's private key, it can be decrypted only using its corresponding public key, ensuring that the data only could have come from the server.Ī certificate is not really necessary because data is secure and cannot easily be decrypted. Anything encrypted with either key can only be decrypted with its corresponding key. With public key cryptography, two keys are created, one public the other private. SSL makes use of what is known as asymmetric cryptography, commonly referred to as public key cryptography (PKI). The Secure Socket Layer (SSL) is used to encrypt the data stream between the web server and a web browser.

This presents a security issue where security and privacy is necessary for credit card and bank transactions. Normal web pages are sent unencrypted over the Internet allowing anyone to intercept them and read their content. Stunnel is configured for server operation allowing a secure connection between Apache and a browser client. Stunnel is very flexible this page provides additional information for Uniform Server 3.5-Apollo’s implementation.
