I can give you an article on how to log in to Python, exit R and S (private and public keys).
Understanding the form of the Ethereum sign
The signature of Ethereum is based on the elliptical curve’s digital signature algorithm (ECDSA). The signature format consists of signatures, R and S components. Here is a sharing of form:
Signature_hash
: Message 64 bytes mix
R
: 256 -bit public major component
S
: 256 -bit the private key component
Python code
Here’s an example of a Python code fragment that shows you how to get R and S components from the signature:
`Python
hash
Crypto.publickey Imports C
Set the signatureHHH
Signature_hash = B '\ x02 \ x01 \ x00 \ x03 \ x12 \ x11 \ x14'
Remove the signatures (hex)
Hex_signature_hash = signature_hash.hex ()
Get public main ingredients
Public_key = EC (). key
R_component = hex (signature_hash) .RPlace ('\ x00', '')
S_component = hersa (public_key.r)
note: elliptic curve y instead of using x
Print (F "R_Component (bytes): {r_component}")
Print (f "s_component (hessa): {s_component}")
Explanation
- First, we define the signaturehhht syllable.
- We bring the signatter -Hash value in the hex format using the HEX () method.
- Note that we use x
"y" y "y" because ECDSA is based on elliptic curves with a different curve than RSA.
- We may bring r and s components by converting a hexagonal to a signaturehandus to a syllable by using a "replacement ('\ x00') method that removes all zero characters ( \ x00
). R component is now in the syllable but component Stays in the hex.
Note : Ethereum ECDSA uses a different curve than RSA. "Y We use” x “because the elliptical curve instead uses x.
Example use of use
You can check the signature’s authenticity and integrity to check this code fral. For example, you can create a new public key component using the following code:
`Python
Public_key = EC (). key
Print (public_key)
This removes the public main component in syllable form.
