bitcoin in tiny pieces

These are Python scripts made from scracth to play with Bitcoin addresses: public, private, WIF...

The scripts are compatible with Python 2 and Python 3.

before start

Install base58 for Python (tested with base58-1.0.0):

$ pip install base58

notes of usage

The scripts contain useful comments and links to documentation. Also contain configuration variables that can be preset:

Each script can be configured with at least the variable VERBOSE which can be True or False: if you want to concatenate scripts in command-line with |, you need to set VERBOSE = False.

bitcoin-address-from-public-key.py contains the variable COMPRESS_PUBKEY that accepts the values 0 to 3 in order to print uncompressed, compressed, hybrid, or all of the valid formats of a public bitcoin address.

bitcoin-wif-from-private-key.py contains the variable COMPRESS_PUBKEY that accepts the values 0 to 2 in order to print uncompressed, compressed, or both formats of WIF.

notes for Windows users

The folder batchs for Windows contains .bat files for ease of usage with Windows:

• be sure you have Python in your %PATH%, or prepend the Python path to python inside each .bat

• modify inside each .bat the complete path to the folder where you've copied all these Python scripts

• Now usage in Windows is as easy as with Linux:

    C:\> echo 0x01 | bitcoin-public-from-private | bitcoin-address-from-public-key
        1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm
        1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH
        1BFvJKK757eGXdNHkXkgem4fWZU28d1cnk
  

Please, see notes of usage above for configuring outputs and using with | concatenation.
