Usage:

1. Create your public key
2. pub_key=encrypt.encrypt(pass_word)
3. save pub_key to the file gmail.pub
4. Replace 'sample@gmail.com' in mail.py with your own gmail address
5. Run send_mail.py, here you have two choices:

• $./send_mail.py then type your password
• $ echo "your_password" | ./send_mail.py for Unix-like system.

Example:

1. Download as zip and extract

"""
This program effectively encodes and transforms data to QR code.

Encoding work flow:
    ascii string --to-byte-array-->--bz2-compress--> byte array (bit256 array)
    --to-int--> large int --re-partition-by-45--> bit45 array --using-D--> encoded array

# Given func() and cond(), assume there is a number A such that
#     cond(func(x)) == 0 if x < A
#                   == 1 if x >= A
# line search will find the number A according to func() and cond().
# Starting from point=x0 with step=s0, the searching has two phases:
# 1) expanding and 2) concentrating.
#
# 1) Expanding
# In the expanding phase, if cond(func(x0)) == 0,
# then we take larger and larger steps toward positive,
