possible to decode bitcoin address from 'scriptSig' in a raw transaction?

[derrend]

Code:

7.  "in":[
8.    {"prev_out":
9.      {"hash":"2007ae...",
10.      "n":0},
11.    "scriptSig":"304502... 042b2d..."}],

Line 11 contains the signature of the person sending the money,
304502..., followed by a space, and then the corresponding public key, 04b2d.... Again, these are both in hexadecimal.

Can I convert the public key in scriptSig back into it's corresponding bitcoin address or is this not possible?
Thanks

Yes, there are many utilities to do that, or you can write your own.  For example:

Code:

$ echo 0406b7bb1663fc7b6a8a5630038a393581fe24c4fa6da64d94fd76de758885809f40ba54c40b95040294defc84d255079b4a13d1f784c1cf271dbc0d4e864a1696 | sx addr

I did it with gferrin's bitcoin-code,
My confusion stemmed from the

Code:

base58.public_key_to_bc_address()

function in gavinandresen's bitcointools giving me the wrong result. (most likely I am running the wrong version or something)

Thank you for the pointers fellas
