writing long view tags

I want to write a program which would download all post offices given a postal code(pin code) from: http://www.indiapost.gov.in/pin/pinsearch.aspx Type in: 570001 and press Search. Now see the html source. The form is passing some encrypted values. It has some similarity to encode_base64 function in perl/php but I could not decode it.

I'm pasting one line from the code. In the post request this form is sending some encrypted values. I want to decipher the type of encryption used in .com related modules:

(I'm tagging javascript,php,.net because person working in that field may recognize this pattern)

Instead of working against the grain, why don't you just use a website that makes the data public:

http://www.melissadata.com/lookups/nearpostoffice.asp

Then if you look at a post office location:

http://www.melissadata.com/lookups/NearPostOffice.asp?po=ALL&zipcode=60611

It displays it table format. If you need this information just screen scrape and make sure if you use this information on your own website to say where you got the information. I don't believe its necessary to do so but it is always a good idea to cite your sources.


This is an ASP.NET ecrypted ViewState. It most likely does not contain the values you're looking for, and is specifically designed to be difficult to decrypt client-side. Even if it did have postal-code information in it, trying to hack the encryption would be a) far more trouble than it's worth, and b) on shaky ground legally and ethically.

Unless the DVD costs more than, say, 40 hours of your time as a programmer, I highly recommend you just buy it, or else try GeoNames or any of the services in this Stack Overflow thread.
