Frankly, trying to save myself some work here by taking advice from others who've already been there! 1) Aim to sell books through eBay, accepting PayPal. 2) Want best security, to stop copy/print/lend to pal using same password. 3) Intend to send purchased file through a file hosting/sending service, as too big for email attachments. 4) Can therefore send required password(s) as a text message along with the file.... Q) Have I misunderstood, or do I save that list of 999, with buyer's name in next column, on Excel? Or am I, as usual, missing something here?! Regards to all and thanks in advance....
How are you with PHP and MySQL? You could use PayPal's IPN to send the buyers info to your web site, which is then logged into a database. Also, you'd need a routine to email the customer with instructions on downloading the ebook.
When the ebook is opened there's a link to your web site, where the customer signs in with the email used with PayPal. Also, they need to enter the registration code. Once the customer is verified the registration code is stored in association with their email address.
The customer is then supplied with the correct password to unlock the ebook. It also allows them to retrieve their password at anytime in the future and all that is required is their email address.
That's not all! As a bonus the ebook can then be passed on to someone else and if you use HYPrLock you can have the next customer buy directly from you and get the needed password--except this time they won't need to access the database.
Well! Slap my thigh in surprise!! It's Storyman, my personal font of all knowledge! Forget Jeeves - Storyman's your boy!! My friend, I have to say that my knowledge of SQL etc. is ...er....scant. For scant, read non-existant! Not selling from website - selling though eBay, hence the PayPal reference... Have to confess that the more I've read about these passwords, the more confused I've got.... I think I need a Noddy guide to it.... (Oh, no! - Perhaps it's an age thing!)
What I outlined is for eBay sales (that go through PayPal.) I'm not in favor of using online databases for handling money. Fortunately, PayPal sends all the customer info you need after they complete the payment. Check out PayPal's Dev. Site. You'll find a lot of useful info there. Most of what you want is already available.
Here's how the passwords work. The first time the ebook is run on a person's system a number from 0 to 999 is derived using the C drive's serial number as a seed (the source of the seed number can be selected.)
When you created the ebook (w/ 1,000 passwords) a different password was assigned to each of the sequental numbers from 0 to 999.
Let's say the ebook decides that the registration number is #443 what it expects to see before unlocking the ebook is the password that corresponds to #443. That's all there is.
Er....r -i -g -h -t..... Am I missing something again here? You buy from my eBay listing - I get the eBook to you(one way or another) - you unzip and run - except it asks you for a password when you try to... I'm really sorry! I don't understand! Just using your example as an ...er...example, how would I know that your PC would expect the password that equates with #443? I'm sorry! I'm must be particularly thick tonight! I'm getting ready to exclaim "Doh!" and slap my forehead in annoyance.....or perhaps not....!
1) To unlock the ebook the user must enter the password that corresponds to the registration code that their ebook displays.
2) If you use HYPrLock the user can click on 'Buy Now' and purchase the ebook through PayPal (or ClickBank). At the conclusion the user is automatically given the password to unlock their ebook.
3) In addition to HYPrLock's 'Buy Now' button you could also include a button that read 'If Purchased On eBay.' The integration specifics were outlined earlier.
4) You are asking for advanced features. In order to use those advanced features you are going to either: a) learn some PHP/MySQL programming; b) hire someone to program it for you; c) buy some programs already written and patch them together to get what you want; or d) forget it!
Take some time and re-read the manual where the topic of passwords is covered in detail.
No - you've misunderstood me, Storyman - I wasn't asking for advanced features. I just didn't understand how the intended book reader would know what number password he/she would require - I didn't realise that a window opened telling them! It's all clear now - thankyou!
