No interest..

How about 15 BTC?

Thanks.

Escrow is required, here is a timestamped pic:

With only 45 in circulation, this is the least produced of all the sub-500 BTC Casascius coins.

Looking to sell for 15 BTC, negotiable. The item is untouched in it's original case.

Edit: escrow is required, timestamped pic in the posts below.

Edit: lowered price

Using the pycoin library for ecdsa and address stuff.

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:
run with
