CertMgr Class
Properties Methods Events Config Settings Errors
The CertMgr class is used to create, read, and manage certificates.
Syntax
class ipworksauth.CertMgr
Remarks
The class methods, such as list_certificate_stores or list_store_certificates, are used to list certificate stores and certificates. The corresponding lists are returned through the on_store_list and on_cert_list events. Encoded certificates are provided through the events.
You can load a certificate by setting the cert property of the class. Then you can get information about the certificate through the corresponding fields of the cert property (described below).
The cert_subject, cert_serial_number, and cert_issuer properties identify the certificate. The cert_effective_date and cert_expiration_date show the time boundaries of the certificate.
cert_public_key, cert_public_key_algorithm, cert_public_key_length, and cert_version provide information about the certificate keys and the certificate format (version).
cert_usage_flags specifies the intended usage of the certificate. The cert_usage property provides a text description of these flags.

Remarks
The subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.
If an exact match is not found, the store is searched for subjects containing the value of the property.
If a match is still not found, the property is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
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 as follows:
| Field | Meaning |
| CN | Common Name. This is commonly a hostname like www.server.com. |

export_private_key Property
This controls whether to export the private key.
Syntax
def get_export_private_key() -> bool: ... def set_export_private_key(value: bool) -> None: ...
export_private_key = property(get_export_private_key, set_export_private_key)
Default Value
TRUE
Remarks
This property controls whether the private key is exported when export_certificate is called.
If set to True (default), the private key is exported. If set to False, only the public key is exported.
check_crl Method
This method checks the Certificate Revocation List (CRL) specified by the currently loaded certificate.
Syntax
def check_crl() -> None: ...
Remarks
This method will check the CRLs specified by the currently loaded cert.
The class will first obtain the list of CRL URLs from the certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the certificate.
If the certificate has been revoked or any other issues are found during validation, the class fails with an error. To check whether the certificate supports the CRL extension, use the HasCRL configuration setting.
check_ocsp Method
This method uses Online Certificate Status Protocol (OCSP) to check the status of the currently loaded certificate.
Syntax
def check_ocsp() -> None: ...
Remarks
This method will use OCSP to check the validity of the currently loaded cert.
The class will first obtain the OCSP URL from the certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the certificate.
If the certificate has been revoked or any other issues are found during validation, the class fails with an error. To check whether the certificate supports the OCSP extension, use the HasOCSP configuration setting.
config Method
Sets or retrieves a configuration setting.
Syntax
def config(configuration_string: str) -> str: ...
Remarks
config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
create_certificate Method
This method creates a new self-signed certificate in the current store.
Syntax
def create_certificate(cert_subject: str, serial_number: int) -> None: ...
Remarks
This method creates a new self-signed certificate in the current store, which contains the following:
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 as follows:
| Field | Meaning |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email 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 time validity of the new certificate is determined by the CertValidityTime configuration setting, and the key size by the CertKeyLength configuration setting.
In the Unix edition of the toolkit, the certificate will be created in memory. Call export_certificate to export the newly created certificate to a PEM file.
create_key Method
This method creates a new keyset associated with the provided name.
Syntax
def create_key(key_name: str) -> None: ...
Remarks
This method will create a new keyset (public/private key pair) within the Cryptographic Service Provider (CSP) used by the class. The CSP can be set using the CSP configuration setting.
Note: This functionality is only available in Windows.
delete_certificate Method
This method deletes the currently selected certificate from the store.
Syntax
def delete_certificate() -> None: ...
Remarks
This method will delete the selected certificate from the store. If the certificate cannot be deleted, an error is returned.
This functionality is currently not available when the provider is OpenSSL.
delete_key Method
This method deletes the keyset associated with the provided name.
Syntax
def delete_key(key_name: str) -> None: ...
Remarks
This method will delete the keyset (public/private key pair) associated with KeyName from the Cryptographic Service Provider (CSP). The CSP can be set using the CSP configuration setting.
Note: This functionality is only available in Windows.
export_certificate Method
This method exports the currently selected certificate.
Syntax
def export_certificate(cert_file: str, password: str) -> None: ...
Remarks
This method exports the certificate currently selected by cert_subject to the file specified by the CertFile parameter in the format specified by export_format. This method may be used effectively to convert between a variety of formats.
The Password parameter specifies a password for the private key when export_private_key is set to True. Password is not applicable when export_private_key is set to False.
If CertFile is set to an empty string, the exported certificate will not be written to disk and instead will be held as a string by the exported_cert property.
export_format is applicable when export_certificate is called and may be used to specify the output format. The applicability of each format depends on whether export_private_key is set. Some formats are applicable only when exporting to a private key and some values are applicable only when exporting to a public key.
| ExportFormat | Applicability | Description |
| "PFX" or "PKCS12" (default) | Private Keys | A PFX file (PKCS12). |
| "PEM" | Public and Private Keys |
A PEM-formatted public certificate (X509/PKCS1/PKCS8), or PEM formatted private key (PKCS1/PKCS8). When export_private_key is False the exported certificate will be a PEM formatted X509 public certificate if the certificate being exported includes X509 data. If no X509 information is present, the public key will be exported in PKCS1 public key format for RSA/DSA keys and PKCS8 public key format for ECDSA/EdDSA keys. When export_private_key is True the exported certificate will be a PEM-formatted PKCS1 private key for RSA/DSA keys and a PEM-formatted PKCS8 private key for ECDSA/EdDSA keys.

certmgr.SetExportPrivateKey(false);
certmgr.SetExportFormat("SSH2PublicKey");
ret_code = certmgr.ExportCertificate("C:\\ssh2.pub", "");
generate_csr Method
This method generates a new Certificate Signing Request (CSR) to be sent to a signing authority.
Syntax
def generate_csr(cert_subject: str, key_name: str) -> str: ...
Remarks
This method will generate a new CSR to be sent to the signing authority. CertSubject specifies the subject of the CSR. KeyName specifies the name of the keyset (public/private key pair) to be used. If the keyset does not already exist in the Cryptographic Service Provider (CSP), the class will automatically generate one. To set the CSP, use the CSP configuration setting.
Note: Remember the name of the keyset that is used when creating a CSR. The keyset must be re-associated with the certificate after the trust authority has signed the CSR.
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 as follows:
| Field | Meaning |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email Address |
If a field value contains a comma, it must be quoted.
Note: This functionality is only available in Windows.
import_certificate Method
This method imports a certificate from a file into the current certificate store.
Syntax
def import_certificate(cert_file: str, password: str, subject: str) -> None: ...
Remarks
This method will import a certificate from a file into the current certificate store.
On Windows platforms, certificates may be imported only to the Windows certificate store. To load a certificate without importing it to a Windows store, set cert.
Certificate files with or without a private key may be imported. If the file specified by CertFile contains a private key, the private key will be imported along with the public certificate. If the file specified by CertFile contains only a public certificate, only the public certificate will be imported.
The Password parameter specifies the certificate password (if any). When importing a public certificate, set Password to an empty string.
The format of the certificate file being imported must contain valid X509 data to be imported. Not all certificate file formats include X509 data, such as PPK or PKCS8 private keys. If the CertFile is of a format that cannot be imported, the class fails with an error.
Note: On Linux-based operating systems, this method loads the specified certificate without importing into any system location.
Subject is optional. If empty, the first certificate in the store is loaded instead of the matching certificate.
ImportCertificate Example
//Import a PFX
certmgr.ImportCertificate("..\\test.pfx", "password", "*");
//Import a public certificate (CER)
certmgr.ImportCertificate("..\\test.cer", "", "*");
import_signed_csr Method
This method imports a signed Certificate Signing Request (CSR).
Syntax
def import_signed_csr(signed_csr: bytes, key_name: str) -> None: ...
Remarks
This method will import a signed CSR. SignedCSR specifies a certificate that has been signed by a trusted authority. KeyName is the name of the keyset (public/private key pair) that was used to create the original CSR.
Note: This functionality is only available in Windows.
issue_certificate Method
This creates a new certificate in the current store and is signed by the selected certificate.
Syntax
def issue_certificate(cert_subject: str, serial_number: int) -> None: ...
Remarks
This method creates a new certificate in the current store and is 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 as follows:
| Field | Meaning |
| CN | Common Name. This is commonly a hostname like www.server.com. |
| O | Organization |
| OU | Organizational Unit |
| L | Locality |
| S | State |
| C | Country |
| E | Email 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 before 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.
list_certificate_stores Method
This lists the certificate stores.
Syntax
def list_certificate_stores() -> str: ...
Remarks
This method lists the system certificate stores for the current user account. The results are provided through the on_store_list event.
The same information is also returned upon method completion as a set of lines and is given one per certificate store name.
Note: This functionality is only available in Windows.
list_keys Method
This lists the keysets in a Cryptographic Service Provider (CSP).
Syntax
def list_keys() -> str: ...
Remarks
This method lists the keys (public/private key pairs) in a CSP. The results are provided through the on_key_list event.
The same information is also returned upon method completion as a set of lines and is given one per key, with each line containing the following information separated by Tab characters: KeyContainer, KeyType, AlgId, and KeyLen.
Note: This functionality is only available in Windows.
list_machine_stores Method
This lists the machine certificate stores.
Syntax
def list_machine_stores() -> str: ...
Remarks
This method behaves the same as the list_certificate_stores method, but it lists the certificate stores in the machine account (under HKEY_LOCAL_MACHINE in the registry).
Note: This functionality is only available in Windows.
list_store_certificates Method
This lists the certificates in a store.
Syntax
def list_store_certificates() -> str: ...
Remarks
This method lists the certificates in a store. The results are provided through the on_cert_list event.

Remarks
This event is fired for every certificate in the certificate chain of the certificate assigned to the class.
The TrustStatus parameter contains information about the trust status of the entire certificate chain. A value of 0 signifies that the security subsystem has verified the certificate. Other values are combinations of one or more of the following flags:
| 0x00000001 | This certificate or one of the certificates in the certificate chain is not time valid. |
| 0x00000002 | Certificates in the chain are not properly time nested. |
| 0x00000004 | Trust for this certificate or one of the certificates in the certificate chain has been revoked. |
| 0x00000008 | This certificate or one of the certificates in the certificate chain does not have a valid signature. |
| 0x00000010 | The certificate or the certificate chain is not valid for its proposed usage. |
| 0x00000020 | The certificate or certificate chain is based on an untrusted root. |
| 0x00000040 | The revocation status of the certificate or one of the certificates in the certificate chain is unknown. |
| 0x00000080 | One of the certificates in the chain was issued by a certification authority that the original certificate had certified. |
| 0x00010000 | The certificate chain is not complete. |
| 0x00020000 | A certificate trust list (CTL) used to create this chain was not time valid. |
| 0x00040000 | A CTL used to create this chain did not have a valid signature. |
| 0x00080000 | A CTL used to create this chain is not valid for this usage. |
The TrustInfo parameter contains additional information about the status of the entire certificate chain. It is a combination of one or more of the following flags:
| 0x00000001 | An exact match issuer certificate has been found for this certificate. |
| 0x00000002 | A key match issuer certificate has been found for this certificate. |
| 0x00000004 | A name match issuer certificate has been found for this certificate. |
| 0x00000008 | This certificate is self-signed. |
| 0x00010000 | The certificate chain created is a complex chain. |
The CertSubject and CertIssuer parameters contain the distinguished names of the certificate owner and issuer, respectively.

KeyType shows the key type: 1 for key exchange (encryption) keys, and 2 for digital signature keys.
KeyLen shows the length of the public key (in bits).
on_log Event
This event fires once for each log message.
Syntax
class CertMgrLogEventParams(object): @property def log_level() -> int: ... @property def message() -> str: ... @property def log_type() -> str: ... # In class CertMgr: @property def on_log() -> Callable[[CertMgrLogEventParams], None]: ... @on_log.setter def on_log(event_hook: Callable[[CertMgrLogEventParams], None]) -> None: ...
Remarks
This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
| 0 (None) | No events are logged. |
| 1 (Info - default) | Informational events are logged. |
| 2 (Verbose) | Detailed data are logged. |
| 3 (Debug) | Debug data are logged. |

The default value is False.
| 1 | CERT_STORE_ADD_NEW - Imports a certificate only if no existing certificate is present. |
| 2 | CERT_STORE_ADD_USE_EXISTING - If an existing certificate is found, it is not replaced. |
| 3 (default) | CERT_STORE_ADD_REPLACE_EXISTING - If an existing certificate is found it is replaced. |
| 4 | CERT_STORE_ADD_ALWAYS - No checks are performed and a new certificate is always added to the store. This can result in duplicates. |
| 5 | CERT_STORE_ADD_REPLACE_EXISTING_INHERIT_PROPERTIES - If an existing certificate is found it is replaced, and the new certificate inherits properties from the certificate it replaces. |
| 6 | CERT_STORE_ADD_NEWER - Imports a certificate only if the certificate is newer than an existing matching certificate. |
| 7 | CERT_STORE_ADD_NEWER_INHERIT_PROPERTIES - Imports a certificate only if the certificate is newer than an existing matching certificate, and inherits the properties of old certificate it replaces. |
This config can take one of the following values:
| 2 (cstPFXFile) | The certificate store is the name of a PFX (PKCS12) file containing certificates. |
| 3 (cstPFXBlob) | The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format. |
| 6 (cstPEMKeyFile) | The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate. |
| 7 (cstPEMKeyBlob) | The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate. |
| 8 (cstPublicKeyFile) | The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate. |
| 9 (cstPublicKeyBlob) | The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate. |
| 10 (cstSSHPublicKeyBlob) | The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key. |
| 13 (cstSSHPublicKeyFile) | The certificate store is the name of a file that contains an SSH-style public key. |
| 99 (cstAuto - default) | The certificate type is automatically determined from the input. |
Valid values are:
- (empty string)
- HS256
- HS384
- HS512
- RS256
- RS384
- RS512
- EC256

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to True. This is a static setting that applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.
For more details, please see the FIPS 140-2 Compliance article.
Note: This setting is applicable only on Windows.
Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.
Setting this configuration setting to True tells the class to use the internal implementation instead of using the system security libraries.
On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.
To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
