Information for Today – (17/11/2011)

Hi to all,

Today I came to know  some information by doing google. I would like to share that information to you.

* SSL

SSL (Secure Sockets Layer) is the standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is an industry standard and is used by millions of websites in the protection of their online transactions with their customers.
* LDAP
How do you look up an address for someone who’s never sent you email? How can an organization keep one centralized up-to-date phone book that everybody has access to?

software companies such as Microsoft, IBM, Lotus, and Netscape to support a standard called LDAP.

“LDAP-aware” client programs can ask LDAP servers to look up entries in a wide variety of ways. LDAP servers index all the data in their entries, and “filters” may be used to select just the person or group you want, and return just the information you want.

For example, here’s an LDAP search translated into plain English: “Search for all people located in Chicago whose name contains “Fred” that have an email address. Please return their full name, email, title, and description.”
LDAP was designed at the University of Michigan to adapt a complex enterprise directory system (called X.500) to the modern Internet. X.500 is too complex to support on desktops and over the Internet, so LDAP was created to provide this service “for the rest of us.”
LDAP servers exist at three levels: There are big public servers, large organizational servers at universities and corporations, and smaller LDAP servers for workgroups. Most public servers from around year 2000 have disappeared, although directory.verisign.com exists for looking up X.509 certificates. The idea of publicly listing your email address for the world to see, of course, has been crushed by spam.
If you found that any of the information which i have stated is incorrect. Let me help to correct.
Thanks,
With Regards,
V. Balakrishnan.
