python import subprocess


def verify_certificate(certificate_path):

try:

# Use the Windows command-line tool 'certutil' to verify the certificate

command = f'certutil -verify "{certificate_path}"'

result = subprocess.run(command, capture_output=True, text=True)
 if "Certificate is valid" in result.stdout:

print("Certificate is valid.")

else:

print("Certificate is invalid or malformed.")
 except Exception as e:

print(f"An error occurred while verifying the certificate: {e}")
def verify_timestamp_signature(file_path):

try:

# Use the Windows command-line tool 'signtool' to verify the timestamp signature

command = f'signtool verify /pa "{file_path}"'

result = subprocess.run(command, capture_output=True, text=True)
 if "Successfully verified" in result.stdout:

print("Timestamp signature is verified.")

else:

print("Timestamp signature is either not verifiable or malformed.")
 except Exception as e:

print(f"An error occurred while verifying the timestamp signature: {e}")
# Example usage

certificate_path = "C:\\path\\to\\certificate.cer"

file_path = "C:\\path\\to\\file.exe"

verify_certificate(certificate_path) verify_timestamp_signature(file_path)

Note: The provided code is a basic example that utilizes the Windows command-line tools ‘certutil’ and ‘signtool’ to verify a certificate and timestamp signature, respectively. It is important to ensure that these tools are installed and accessible in the Windows environment. Additionally, the code might require further adjustments based on the specific requirements and error handling of the actual use case.
