CertMgr Component
Properties Methods Events Config Settings Errors
The CertMgr component is used to create, read, and manage certificates.
Syntax
nsoftware.IPWorksAuth.CertMgr
Remarks
The component methods, such as ListCertificateStores or ListStoreCertificates, are used to list certificate stores and certificates. The corresponding lists are returned through the StoreList and CertList events. Encoded certificates are provided through the events.
You can load a certificate by setting the Cert property of the component. Then you can get information about the certificate through the corresponding fields of the Cert property (described below).
The Subject, SerialNumber, and Issuer fields identify the certificate. The EffectiveDate and ExpirationDate show the time boundaries of the certificate.
PublicKey, PublicKeyAlgorithm, PublicKeyLength, and Version provide information about the certificate keys and the certificate format (version).
UsageFlags specifies the intended usage of the certificate. The Usage field provides a text description of these flags.

ExportPrivateKey Property (CertMgr Component)
This controls whether to export the private key.
Syntax
Default Value
True
Remarks
This property controls whether the private key is exported when ExportCertificate is called.
If set to True (default), the private key is exported. If set to False, only the public key is exported.
CheckCRL Method (CertMgr Component)
This method checks the Certificate Revocation List (CRL) specified by the currently loaded certificate.
Syntax
public void CheckCRL(); Async Version public async Task CheckCRL(); public async Task CheckCRL(CancellationToken cancellationToken);
Public Sub CheckCRL() Async Version Public Sub CheckCRL() As Task Public Sub CheckCRL(cancellationToken As CancellationToken) As Task
Remarks
This method will check the CRLs specified by the currently loaded Cert.
The component will first obtain the list of CRL URLs from the certificate's CRL distribution points extension. The component 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If the certificate has been revoked or any other issues are found during validation, the component throws an exception. To check whether the certificate supports the CRL extension, use the HasCRL configuration setting.
CheckOCSP Method (CertMgr Component)
This method uses Online Certificate Status Protocol (OCSP) to check the status of the currently loaded certificate.
Syntax
public void CheckOCSP(); Async Version public async Task CheckOCSP(); public async Task CheckOCSP(CancellationToken cancellationToken);
Public Sub CheckOCSP() Async Version Public Sub CheckOCSP() As Task Public Sub CheckOCSP(cancellationToken As CancellationToken) As Task
Remarks
This method will use OCSP to check the validity of the currently loaded Cert.
The component will first obtain the OCSP URL from the certificate's OCSP extension. The component 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 component throws an exception. To check whether the certificate supports the OCSP extension, use the HasOCSP configuration setting.
Config Method (CertMgr Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.
CreateCertificate Method (CertMgr Component)
This method creates a new self-signed certificate in the current store.
Syntax
public void CreateCertificate(string certSubject, int serialNumber); Async Version public async Task CreateCertificate(string certSubject, int serialNumber); public async Task CreateCertificate(string certSubject, int serialNumber, CancellationToken cancellationToken);
Public Sub CreateCertificate(ByVal CertSubject As String, ByVal SerialNumber As Integer) Async Version Public Sub CreateCertificate(ByVal CertSubject As String, ByVal SerialNumber As Integer) As Task Public Sub CreateCertificate(ByVal CertSubject As String, ByVal SerialNumber As Integer, cancellationToken As CancellationToken) As Task
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.
CreateKey Method (CertMgr Component)
This method creates a new keyset associated with the provided name.
Syntax
public void CreateKey(string keyName); Async Version public async Task CreateKey(string keyName); public async Task CreateKey(string keyName, CancellationToken cancellationToken);
Public Sub CreateKey(ByVal KeyName As String) Async Version Public Sub CreateKey(ByVal KeyName As String) As Task Public Sub CreateKey(ByVal KeyName As String, cancellationToken As CancellationToken) As Task

Remarks
This method exports the certificate currently selected by Cert to the file specified by the CertFile parameter in the format specified by ExportFormat. This method may be used effectively to convert between a variety of formats.
The Password parameter specifies a password for the private key when ExportPrivateKey is set to True. Password is not applicable when ExportPrivateKey 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 ExportedCert property.
ExportFormat is applicable when ExportCertificate is called and may be used to specify the output format. The applicability of each format depends on whether ExportPrivateKey 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 ExportPrivateKey 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 ExportPrivateKey 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. For example, when ExportPrivateKey is False: -----BEGIN CERTIFICATE----- MIIBkTCB+6ADAgECAgEBMA0GCSqGSIb3DQEBBQUAMA4xDDAKBgNVBAMTAzEwMDAgFw0wNzAx ...

GenerateCSR Method (CertMgr Component)
This method generates a new Certificate Signing Request (CSR) to be sent to a signing authority.
Syntax
public string GenerateCSR(string certSubject, string keyName); Async Version public async Task<string> GenerateCSR(string certSubject, string keyName); public async Task<string> GenerateCSR(string certSubject, string keyName, CancellationToken cancellationToken);
Public Function GenerateCSR(ByVal CertSubject As String, ByVal KeyName As String) As String Async Version Public Function GenerateCSR(ByVal CertSubject As String, ByVal KeyName As String) As Task(Of String) Public Function GenerateCSR(ByVal CertSubject As String, ByVal KeyName As String, cancellationToken As CancellationToken) As Task(Of String)
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 component 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.
ImportCertificate Method (CertMgr Component)
This method imports a certificate from a file into the current certificate store.
Syntax
public void ImportCertificate(string certFile, string password, string subject); Async Version public async Task ImportCertificate(string certFile, string password, string subject); public async Task ImportCertificate(string certFile, string password, string subject, CancellationToken cancellationToken);
Public Sub ImportCertificate(ByVal CertFile As String, ByVal Password As String, ByVal Subject As String) Async Version Public Sub ImportCertificate(ByVal CertFile As String, ByVal Password As String, ByVal Subject As String) As Task Public Sub ImportCertificate(ByVal CertFile As String, ByVal Password As String, ByVal Subject As String, cancellationToken As CancellationToken) As Task
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 component throws an exception.
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", "", "*");

The Subject parameter can also take an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load in a "Thumbprint=value" format.
public Certificate(CertStoreTypes storeType, byte[] store, string storePassword, string subject, string configurationString);
Public Certificate(ByVal StoreType As CertStoreTypes, ByVal Store As Byte(), ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)
StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.

StoreType identifies the type of certificate store to use. See for descriptions of the different certificate stores. Store is a byte array containing the certificate data. StorePassword is the password used to protect the store.
After the store has been successfully opened, the component will load Encoded as an X.509 certificate and search the opened store for a corresponding private key.
Config Settings (CertMgr Component)
The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.CertMgr Config Settings
CertMgr certmgr = new CertMgr();
certmgr.Cert = new Certificate();
certmgr.CertStoreType = CertStoreTypes.cstUser;
certmgr.CertStore = "MY";
certmgr.Config("BasicConstraints=30030101FF");

Base Config Settings
In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.
- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.
This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
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 components 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 component 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.
If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.
Note: This setting is static. The value set is applicable to all components used in the application.
When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
