Generate Metahash address

> python crypt_example_bin.py generate
Start generate MetaHash address...
Step 1. Generate private and public keys. Take part of the public key that equals to 65 bytes.
Step 2. Perform SHA-256 hash on the public key.
Done
Step 3. Perform RIPEMD-160 hash on the result of previous step.
Done
Step 4. SHA-256 hash is calculated on the result of previous step.
Done
Step 5. Another SHA-256 hash performed on value from Step 4.  Save first 4 bytes.
Done
Step 6. These 4 bytes from last step added to RIPEMD-160 hash with prefix 0x. 
Your Metahash address is 0x003d3b27f544d1dc03d6802e6379fdcfc25e0b73272b62496b

As a result, output files will be created in your folder:

• 0x003d3b27f544d1dc03d6802e6379fdcfc25e0b73272b62496b_private.pem - private key file
• 0x003d3b27f544d1dc03d6802e6379fdcfc25e0b73272b62496b_public.pub - public key file
• 0x003d3b27f544d1dc03d6802e6379fdcfc25e0b73272b62496b.txt - metahash address file

Fetch balance of Metahash wallet by address

For sending data will be charged a fee equal to the data field length. For example, if data="qwerty", then fee=6.

> python crypt_example_bin.py create-tx --data="qwerty" --to=0x00525d3f6326549b8974ef669f8fced6153109ba60d52d547d --value=1000 --nonce=3 --privkey=mh_private.pem
