Ethereum: ecdsa – Create Private key and Bitcoin Address
The Ecdsa Library in Python.
Ethereum: Generating Private Keys and Creating Bitcoin Addresses
ECDSA (Elliptic Curve Digital Signature Algorithm) Library in Python. We will also create a bitcoin address for a newly generated private key.
Prerequisites
Before You Begin, make sure you have:
- Python 3.x installed on your system
- The Ecdsa Library Installed Via Pip:
Pip Install Fastecdsa
- A code editor or ide to write and run the script
Generating Private Keys with Ecdsa
Here’s an example of how to generate a private key for curve p256:
`python
import binascii
Hashlib import
From Fastecdsa Import Keys, Curve
Generate A New Private Key With Secp256K1 Curve
priv_key = keys.gen_private_key (curve.secp256k1)
Print ("Generated Private Key:")
Binascii.PrintableCode (Priv_Key)
In this example, we use the keys module from ecdsa to generate a new private key. We specify the curve as sec256k1, which is suitable for Ethereum's mainnet.
Creating and Bitcoin Address
Once you have generated your private key, you can create a bitcoin address using thekeys.encode_private_key ()method:
python
Create a Bitcoin Address from the Private Key
Address = Keys.encode_Private_Key (PRIV_KEY)
Print ("Generated Bitcoin Address:")
binascii.printablecode (address)
In this exam, This method is easily converted to a hexadecimal string.
Example Usage
Here’s an example of how you can use these functions together:
`python
import binascii
Generate A New Private Key With Secp256K1 Curve
priv_key = keys.gen_private_key (curve.secp256k1)
Print ("Generated Private Key:")
Binascii.PrintableCode (Priv_Key)
Create a Bitcoin Address from the Private Key
Address = Keys.encode_Private_Key (PRIV_KEY)
Print ("Generated Bitcoin Address:")
binascii.printablecode (address)
This will generate a new private key and create a bitcoin address for it.
Security Considerations
Pairs is inherently insecure. `Function with a Secure Key Pair or Using a Hardware Module (HSM).
