ssl.get_default_verify_paths() Returns a named tuple with paths to OpenSSL’s default cafile and capath. The paths are the same as used by SSLContext.set_default_verify_paths(). The return value is a named tuple DefaultVerifyPaths: cafile - resolved path to cafile or None if the file doesn’t exist, capath - resolved path to capath or None if the directory doesn’t exist, openssl_cafile_env - OpenSSL’s environment key that points to a cafile, openssl_cafile - hard coded path to a cafile, o

ssl.DER_cert_to_PEM_cert(DER_cert_bytes) Given a certificate as a DER-encoded blob of bytes, returns a PEM-encoded string version of the same certificate.

ssl.cert_time_to_seconds(cert_time) Return the time in seconds since the Epoch, given the cert_time string representing the “notBefore” or “notAfter” date from a certificate in "%b %d %H:%M:%S %Y %Z" strptime format (C locale). Here’s an example: >>> import ssl >>> timestamp = ssl.cert_time_to_seconds("Jan 5 09:34:43 2018 GMT") >>> timestamp 1515144883 >>> from datetime import datetime >>> print(datetime.utcfromtimestamp(timestamp)) 2018-01-05 09

ssl.enum_certificates(store_name) Retrieve certificates from Windows’ system cert store. store_name may be one of CA, ROOT or MY. Windows may provide additional cert stores, too. The function returns a list of (cert_bytes, encoding_type, trust) tuples. The encoding_type specifies the encoding of cert_bytes. It is either x509_asn for X.509 ASN.1 data or pkcs_7_asn for PKCS#7 ASN.1 data. Trust specifies the purpose of the certificate as a set of OIDS or exactly True if the certificate is trust

ssl.create_default_context(purpose=Purpose.SERVER_AUTH, cafile=None, capath=None, cadata=None) Return a new SSLContext object with default settings for the given purpose. The settings are chosen by the ssl module, and usually represent a higher security level than when calling the SSLContext constructor directly. cafile, capath, cadata represent optional CA certificates to trust for certificate verification, as in SSLContext.load_verify_locations(). If all three are None, this function can c

sqlite3.version The version number of this module, as a string. This is not the version of the SQLite library.

sqlite3.sqlite_version_info The version number of the run-time SQLite library, as a tuple of integers.

sqlite3.version_info The version number of this module, as a tuple of integers. This is not the version of the SQLite library.

exception ssl.CertificateError Raised to signal an error with a certificate (such as mismatching hostname). Certificate errors detected by OpenSSL, though, raise an SSLError.

keys() This method returns a list of column names. Immediately after a query, it is the first member of each tuple in Cursor.description.
