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 and Elliptic Curve Digital Signature Algorithm (ECDSA) private keys in WIF format, I can guide you on how to do so. 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 the encryption library in Python:

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()
with 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 change the key size if necessary.
).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 change the key size if necessary.
)
pem_data = private_key.private_bytes(
encoding=serialization.Encoding.PEM,
format=serialization.PrivateFormat.PKCS8,
encryption_algorithm=serialization.NoEncryption()
)
return pem_data

Example of use:
file_path_to_pem = 'path/to/file.pem'
wif_private_key_to_convert = convert_wif_to_pem('your_wif_private_key')
print(wif_private_key_to_convert)
file_path_from_wif = wif_private_key_to_convert
with open(file_path_from_wif, "wb") as f:
f.write(convert_pem_to_wif(file_path_to_pem))

Please note that you must have the cryptography library installed (pip install cryptography) and Python 3.7 or later.

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

Again, I want to emphasize that this process involves some cryptographic complexity and should not be attempted without a thorough understanding of the elliptic curve digital signature algorithm (ECDSA) and its use in digital signatures.
