Topic: [ANN] hecs.py: Encrypt text with bitcoin addresses (Read 801 times)
I was thinking about it today, is it not a higher security risk? I mean if someone has a lot of your encrypted messages and finds the key, he/she would also be able to access your money
Using the pycoin library for ecdsa and address stuff.
Which wallet software you using?
To get the pubkey works well:
To get the pubkey works well:

#!/usr/bin/env python
import binascii
import os
import re
import sys
import requests
def search_for_pubkey(address):
response = requests.get('https://blockchain.info/q/pubkeyaddr/' + address)
pubkey_hex = response.text
if len(pubkey_hex) < 16:
raise Exception("Pubkey not found")
return pubkey_hex
import binascii

response = requests.get('https://blockchain.info/q/pubkeyaddr/' + address)
pubkey_hex = response.text
if len(pubkey_hex) < 16:
raise Exception("Pubkey not found")
return pubkey_hex
Interesting idea, I may hack a little with it today
Hi all,
I made a GUI for encrypting messages with bitcoin addresses.
- Source at https://github.com/eudemonia-research/hec
- Screenshots at http://imgur.com/a/iOpyP
- Uses the blockchain.info API to get the public key. Note that they don't have keys from early transactions for some reason
- the session key is encrypted with the public key using the EC group operation
- the message is encrypted with aes in counter mode
- sha256 for the hmac
- tested with python3 only
Plans:
- custom encryption options
- cxfreeze an exe, so my friends who don't wanna learn to use linux can play along
Installation:
It's on pypi. It depends on PyQt5, pycoin, and pycrypto. For some reason I had to install pycoin manually (no idea why).
Install with:
