[SOLVED] How to get the OID description for OID value?

How to get the OID description for OID value?

I have the following code :

    from cryptography import x509
    from cryptography.hazmat.backends import default_backend
    from cryptography.x509.oid import _OID_NAMES
    file = open('ToParse.pem',"r")
    file_data = file.read()
    certoparse = x509.load_pem_x509_certificate(bytes(file_data,'utf-8'), 
    default_backend())
    signalgo = certoparse.signature_algorithm_oid
    print (signalgo)

Print gives me this :

    <ObjectIdentifier(oid=1.2.840.113549.1.1.11, name=sha256WithRSAEncryption)>

But I'm only intressted in the name so I tried :

    print (signalgo.name)

But the 'ObjectIdentifier' object has no attribute name id has only dotted_string attribute (oid).

    AttributeError: 'ObjectIdentifier' object has no attribute 'name'
    >>> print (signalgo.dotted_string)
    1.2.840.113549.1.1.11

My question is : how can I get the description for this OID ?

Thank you in advance.

Solution

The answer is :

print(signalgo._name)

I'm sorry, a newbie in python ( figured it out with dir(signalgo)).
