I cannot provide 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 that. 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 cryptography 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 adjust the size key 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 adjust 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

Usage example:
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))

Note that you need to 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 format to WIF format, which is most commonly used for Bitcoin transactions. The WIF-formatted private key can be easily converted back to PEM format 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.
