Hello all this my first Post Here :D :D

PyBTC it's Simple (script & library)

Bitcoin Address's Generator (offline) , Base58Check (WIF) Encode/Decode , WIF to Bitcoin Address

Ex for using as library

Code:

    >>> from PyBTC import Addr
    >>> Addr('0000000000000000000000000000000000000000000000000000000000000002')
    '1LagHJk2FyCV2VzrNHVqg3gYG4TSYwDV4m'

WIF

Code:

    >>> from PyBTC import WIF
    >>> WIF('0000000000000000000000000000000000000000000000000000000000000002')
    '5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAvUcVfH'

Ex as script

Code:


PyBTC.py -a 
Address :  1LTUNrDmDZTDJxy3PviZxjwDJpvUr2YRu7
Privkey :  3427e5ca8a4b34f2c057b6ebd4372b6a86b6c8ad16831cce7cf5b53bcefc637e
WIF     :  5JDFqFTFDEfvzuxrQrSrvnrTHJKqeTdcNTxWMCQ2VotLZTfPw7v

One concern I'd have is with the PRNG that is in use.

:-)
e.g.

Code:

def rankey():
	rand = random.randint(0x00000,0xfffff)
	key = sha256(str(rand).encode('hex')).hexdigest()
	return key

You should not rely on this code if the part I am looking it is accurate.
You are picking a number between 0 and 0xfffff (1,048,575)

Code:

rand = random.randint(0x00000,0xfffff)

That is not large enough and could be searched in seconds - meaning your coins will be stolen.

You should fix the code.

If you look at the link Newar sent, I think it has a reasonable PRNG in there - I didn't look to see though.

This is a good way to learn about bitcoin, for sure. ;-)

;D Done update it

Code:

def rankey():
	r = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ~!@#$%^&*()"0123456789'
	rand = random.sample(r,64)
	k = ''.join(rand)
	key = sha256(k).hexdigest()
	return key
