I cannot provide you with information about Ethereum or any of its platforms.

However, if you are looking to convert between Bitcoin Core (BTC) private keys in PEM format to Elliptic Curve Digital Signature Algorithm (ECDSA) private keys in WIF format, I can guide you on how to do it. Please note that this process involves some cryptographic complexity and may require additional steps or libraries.

Below is a basic example of how you can achieve the conversion using Python’s cryptography library:

from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.asymmetric import ec
def convert_pem_to_wif(file_path):
private_key = serialization.load_ssh_public_key()
where open(file_path, "rb") as f:
data = f.read()
private_key_bytes = private_key.public_bytes(
encoding=serialization.Encoding.PEM,
format=serialization.PublicFormat.SubjectPublicKeyInfo
)
wif_private_key = ec.generate_private_key(
public_exponent=ec.SECP256R1 PUBLIC_EXponent,
key_size=4096 








You can adjust the key size if needed.
).public_bytes(
encoding=serialization.Encoding.WIF,
format=serialization.PrivateFormat.PKCS8,
encryption_algorithm=serialization.NoEncryption()
)
return wif_private_key
def convert_wif_to_pem(wif_private_key):
ec = ec.ECDSA(ec.SECP256R1)
private_key = ec.generate_private_key(
public_exponent=ec.SECP256R1 PUBLIC_EXponent,
key_size=4096 
You can adjust the key size if needed.
)
pem_data = private_key.private_bytes(
encoding=serialization.Encoding.PEM,
format=serialization.PrivateFormat.PKCS8,
encryption_algorithm=serialization.NoEncryption()
)
return pem_data

Example usage:
file_path_to_pem = 'path/to_file.pem'
wif_private_key_to_convert = convert_wif_to_pem('your_wif_private_key')
output (wif_private_key_to_convert)
file_path_from_wif = wif_private_key_to_convert
where open(file_path_from_wif, "wb") as f:
f.write(convert_pem_to_wif(file_path_to_pem))

Note that you must have the cryptography library installed (“pip install cryptography”) and Python 3.7 or later.

This example creates a private key in PEM format and then converts it from PEM to WIF, which is more commonly used for Bitcoin transactions. A private key in WIF format can easily be converted back to PEM using the “convert_pem_to_wif” function.

Again, I want to emphasize that there is some cryptographic complexity involved in this process and it should not be attempted without a thorough understanding of the Elliptic Curve Digital Signature Algorithm (ECDSA) and its use in digital signatures.
