Thanks for your response TheButterZone. I still have questions though. Do I use the index.html file inside the zip to create new addresses and wallets? Or do I just save the address and private key I generated onto a piece of paper and keep reusing that same address? Why are there two private keys shown? Where do I find how many bitcoins are in my wallet? Where is the operation of the address/wallet generation and safekeeping explained? Thanks again.
1) The index.html is the Graphical User Interface of everything in the zip.
2) You can create new addresses on the Generator page by either putting in a random passphrase that you remember for as long as you want to use the address, or click Secret Exponent and hit the refresh icon.
3) You should save any addresses and private keys you've already put on paper, and any future ones that have been generated without the passphrase(s) you commit to memory from 2)
4) Any private keys already on there are just for example. Always put in your own.
5) To read-only, go to
https://blockchain.info/address/1TBZYXjrGjXCEN1SprpF66Jzy5uN3GiLS and replace my address with yours; to read and spend, click Transactions, input your private key, and it will prompt to download from blockchain.info, click OK, and then you can also send transactions
6) It was never explained to me, it all seemed self-explanatory. I was only told to use the GitHub source offline, rather than brainwallet.org (as brainwallet.org could be hacked and redirected to capture private keys and steal BTC)
