issue_certificate Method

Creates a new certificate in the current store, signed by the selected certificate.


def issue_certificate(cert_subject: str, serial_number: int) -> None: ...


This method creates a new certificate in the current store, signed by the selected certificate. CertSubject specifies the subject of the new certificate. A new keyset (public/private key pair) is generated and associated with the new certificate.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

CNCommon Name. This is commonly a host name like www.server.com.
OUOrganizational Unit
EEmail Address

If a field value contains a comma it must be quoted.

SerialNumber specifies the certificate serial number. All certificates signed by the same issuer must have different (unique) serial numbers.

The current certificate selected by the class will be used as the issuing certificate.

If no certificate has been selected in the current cert_store prior to calling this method, or if the selected certificate does not have an associated private key, the method fails with an error.

The time validity of the new certificate is determined by the CertValidityTime configuration setting, and the key size by the CertKeyLength configuration setting.

NOTE: This functionality is only available in Windows.
