Is there an open source (free) client or code for bitcoin transactions Possible Duplicate:
  How can I accept bitcoins on my website?  




I have a few websites I am working on, but is there an open source code I can use that will allow people to deposit bitcoins on my site to where each user would have a unique deposit address?
In the past, I've implemented this just by asking the standard Bitcoin client to generate a few thousand addresses and then just have the web site give them out one by one. It's a bit slow generating the addresses, but if you let it run overnight, you'll have a virtually unlimited supply.

Don't forget to backup the wallet immediately after doing this!
