Does anyone have a command line script that can be used to create a public address from a private key. I don't want to need bitcoind installed.

Can be php, python, bash, or whatever I can use in linux.

The tool I've heard of before was called Bitcoin Off-The-Grid (https://bitcointalk.org/index.php?topic=23081.0), though I think there may be others now.

There's also vanitygen (https://bitcointalk.org/index.php?topic=25804.0), which I've found useful occasionally just running "vanitygen 1" to get a random private key with associated address, but that doesn't help you if you have a private key already.

Edit: Oh, and I can't believe I forgot pywallet (https://bitcointalk.org/index.php?topic=34028.0). That may be what you're really looking for. Just as a disclaimer, the only one of these I've used personally is vanitygen; but I just haven't needed the others yet.

Do you want to create public addresses for people to pay to? An alternative would be to load a large number of pre-generated addresses into your database, and use one each time someone needs to pay.

There's also wallet-tool from bitcoinj (java but can be compiled to a native binary).

If you compile the CppBlockUtils for Armory, you can do a lot with a very simple python script:

Code:

>>> from armoryengine import *
>>> priv = hex_to_binary('aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa')
>>> binAddr20 = convertKeyDataToAddress(priv)
>>> print hash160_to_addrStr(binAddr20)
'19YCGbqXnsaTNTinE7EzjYS2shhv7BSQw1'

It is a royal pain to compile the CppBlockUtils in Windows, but it is quite easy in Linux. Just follow the instructions on my Building Armory from Source page (http://bitcoinarmory.com/index.php/building-armory-from-source). Perhaps I will add a download to a precompiled CppBlockUtils.so/.dll/.pyd/.whatever for users that want to access armoryengine without compiling anything.
