Yeah. I can see that now. However, from what I can gather now, EC_KEY wants a secret not a private key. So if you pass 'BB7529C7834A210374035F50E884C6CA1E42C6DFB43004463AE3BC38A2585E19' as a paremeter, it's not going to work. How would I go about signing messages with that specific private key?.
sign_message_with_wif_privkey also requires the secret.
So let's say I generate a key through bitaddress.org which gives me WIF format, hex format and all that, how would I go about using that?.
Near as I can figure... the "secret" is the 32 bytes of the private key in hex... converted from a string to an Int...sign_message_with_wif_privkey also requires the secret.

from ecdsa.util import string_to_number, number_to_string
...
class EC_KEY(object):
def __init__( self, k ):
secret = string_to_number(k)
...

class EC_KEY(object):
def __init__( self, k ):
secret = string_to_number(k)

def string_to_number(string):
return int(binascii.hexlify(string), 16)
..
def string_to_number(string):
return int(binascii.hexlify(string), 16)
..
I'll have a mess around tonight... and see if I can come up with some example code to string some of it together.
EDIT: I'm too lazy to hack the code, so I was messing with the Electrum console:
Code:
>> import binascii
>> binascii.unhexlify("E705308F9F19BA9292FB0A9F022CC07666AA4D63C14C097F44A674C52599AF2D")

If you check bitaddress.org with your original WIF key... L4xnRyP8ARQHZ1BwVkUVfk8sMkXsyBJxd9zhEMXci6NjHkFd9ewp or the HEX: E705308F9F19BA9292FB0A9F022CC07666AA4D63C14C097F44A674C52599AF2D you'll see the public address listed: 19M16LN1k5Emc8qBuDEYv9Aggpe2ttuABk
