# Instantiate the class with the file path or the binary file content 
_cert = Certificate(
    pfx_file="./pfx-files/test_file.pfx",
    password=b"123456"
)

# Read PFX file
_cert.read_pfx_file()

# Get Serial Number
print(_cert.serial_number())

# Get not valid before date
print(_cert.not_valid_before())

# Get not valid after date
print(_cert.not_valid_after())

# Get subject name
print(_cert.subject())

# Get owner name
print(_cert.common_name())

# Get Issuer name
print(_cert.issuer())

Using the binary content

If one already have the file in memory, the package can be used instantiating the class as following

_cert = Certificate(
    pfx_file=binary_file_content,
    password=b"123456"
)
