Ethereum: Signing a raw transaction with Python ECDSA (or OpenSSL)

Here is a step-step guide on the liberation of a raw deal using Python ECDSA (or OpenSSL):

Steps 15-17: Raw Transaction Structure and Multiple Multiple

This step includes primary raw, vsize, vin, vin, vin, VOUTE, and deleting it with SHA-256. After that, we will use ECDSA.

Step 15: Creature Raw Transaction Structure

`Python

Import Hashmiliib

Import of Eraman from EC

#Appinate raw transaction data from a file or database

txid = '0x ...' Your TXID is here ... 'Replace with your actual TXID

VSIZE = 1000

Replace with your true VSIZE

Vin = [(txid, 0)] Replace VSIZE

with your true Win

Concrete the raw transaction structure

raw_tx = ec.from_raw_data (Win, VSIZE)

Step 16: Compact Race Transaction Structure

`Python

Create a new SHA-256 Hash object

Hash_obJce = hashlib.sha256 ()

Update Hash with raw transaction structure

hash_object.Uw_tx.po_bytes (d)

Receive Hash's Hexadecura represent

TX_HASH = HASH_OBJECT.HEX valueest ()

Step 17: Sign to Hash with ECDSA

`Python

Import of Eraman from EC

Create a pair of new ECDSA key

Key = ec.ckey.from_raw_data ('Your raw key ...')

Sign to Hash with the general key

Save_tx_hash = yue.sign (tx_hash, e = ec.secpp256r1, watermlib.sha256)

Print (Registration_ TX_HASH)

Replace your TXID here … ‘1000, ,, `.

Full code

`Python

Import Hashmiliib

Import of Eraman from EC

defreadem_raw_tx (TXID, VSIZE, VIN):

Create a new SHA-256 Hash object

Hash_obJce = hashlib.sha256 ()

Update Hash with raw transaction structure

Hash_object.Update ((TXID, VSIZE) list (VIN))

Receive Hash's Hexadecura represent

TX_HASH = HASH_OBJECT.HEX valueest ()

Create a pair of new ECDSA key

Key = ec.ckey.from_raw_data ('Your raw key ...')

Sign to Hash with the general key

Save_tx_hash = yue.sign (tx_hash, e = ec.secpp256r1, watermlib.sha256)

Back (TXID, VSIZE, VIN, TX_HASH, SAVE_TX_HAS)

Example Usage:

txid = '0x ... Your TXID here ...'

VSIZE = 1000

Vin = [(txid, 0)] * VSIZE

raw_tx = ec.from_raw_data (Win, VSIZE)

Save_tx_hash = readem_raw_tx (TXID, VSIZE, VIN)

Print (Registration_ TX_HASH)

Remember to replace your actual labor notes value with your actual data. One of the basic examples of how to redeem a raw deal using Python ECDSA (or Openslsl). You may want to change it in terms of your specific requirements and case on your specific requirements.
