What is SSL? (pronounced as separate letters) Short for Secure Sockets Layer is a protocol developed in 1996 by Netscape for transmitting private documents via the Internet. SSL works by using a private key to encrypt data that's transferred over the SSL connection. By convention, URLs that require an SSL connection start with https: instead of http:

SSL Protocol Client side Client initiates a connection
Client verifies the server’s Digital ID. If requested by the server, the client sends its Digital ID.
When the authentication is complete, the client sends the server a session key encrypted using the server’s public key.
Server side Hello? Server Digital ID
Server responds by sending the client its Digital ID. The server may also request the client’s Digital ID for client authentication.
Client Digital ID Session key
Once a session key is established, secure communications commence between client and server

Why use a SSL Certificate? • Confirms that you are who you say you are in a virtual world. • Encrypts information sent to and from your web server. • Information exchanged with you is private and entirely protected from being viewed or tampered with.

What is in the SSL Certificate? • The domain for which the certificate was issued. • The legal owner of the certificate. • The physical location of the owner. • The validity dates of the certificate. • The server’s public key.

What is all this ‘key’ business? When you create a certificate request your web server generates two unique cryptographic keys: • The Public Key, which is also known as a Certificate Signing Request (CSR) file • The Private Key file Public-Key Cryptography is typically used to protect the session key used by asymmetric encryption algorithm. The Public Key is used to encrypt the session key, which in turn is used to encrypt some data, and the Private Key is used for decryption. The most important thing you can do to protect your certificate and the security of your web site is to backup your Private Key! www.cites.uiuc.edu

Generating a CSR
A CSR cannot be generated without generating a Private Key file nor can the Private Key file be generated without generating a CSR file. In certain web server software platforms like Microsoft IIS, both are generated simultaneously through the Wizard on the web server. Typically, you will be prompted to enter the following information about your Organization in order to generate the Private Key and CSR pair from the web server: Organization Name Organizational unit Country Code State or Province Locality Common Name www.cites.uiuc.edu

CSR MUSTs Generate your Certificate Signing Request (CSR) and back up your private key. There are some fields in your CSR that need to have exact values. Country code US State or province Illinois Locality or city Urbana Organizational name University of Illinois Note:
Do not include the "http:// or https://" in your common name. www.cites.uiuc.edu

Certificate is dead or dying The contact person for the certificate is sent a renewal notice about 1 month prior to certificate expiration. Renewals can occur up to 4 weeks prior to expiration without losing any valid time IF there are no changes in the core certificate information. Generally, submission of a new CSR is required to renew a certificate. Under special circumstances (usually an emergency) a certificate can be re-issued at no additional charge. www.cites.uiuc.edu
