CertMgr Component

Properties   Methods   Events   Configuration Settings   Errors  

The CertMgr component is used to manage the digital certificates installed on a system.

Syntax

nsoftware.IPWorks.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.

Cert Property (CertMgr Component)

This is the currently selected certificate.

Syntax

public Certificate Cert { get; set; }
Public Property Cert As Certificate

Remarks

This property is populated when a specified certificate is found or loaded by the component. It is used to specify private or public keys. Set this property to a valid Certificate object to load a certificate and perform different operations, such as DeleteCertificate or ExportCertificate.

CertExtensions Property (CertMgr Component)

This is a list of extensions used by the currently selected certificate.

Syntax

public CertExtensionList CertExtensions { get; }
Public Property CertExtensions As CertExtensionList

Remarks

This property contains a list of extensions used by the currently selected certificate. When Cert is set, the component will read out any CertExtension and populate this list. This list also may be populated by the user before a call to CreateCertificate to add certificate extensions to the certificate to be created.

This property is not available at design time.

CertStore Property (CertMgr Component)

This is the certificate store to search for certificates.

Syntax

public string CertStore { get; set; }
public byte[] CertStoreB { get; set; }
Public Property CertStore As String
Public Property CertStoreB As Byte()

Default Value

"MY"

Remarks

The CertStoreType property specifies the type of the certificate store specified by CertStore. If the store is password protected, specify the password in CertStorePassword.

Designations of certificate stores are platform-dependent.

The following are designations of the most common User and Machine certificate stores in Windows:

MYA certificate store holding personal certificates with their associated private keys.
CACertifying authority certificates.
ROOTRoot certificates.

When the certificate store type is PFXFile, this property must be set to the name of the file. When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

CertStorePassword Property (CertMgr Component)

This is the password for the certificate store (if any).

Syntax

public string CertStorePassword { get; set; }
Public Property CertStorePassword As String

Default Value

""

Remarks

The value of this property is used to open the certificate store if the certificate store requires a password.

CertStoreType Property (CertMgr Component)

This is the type of certificate store for CertStore .

Syntax

public CertStoreTypes CertStoreType { get; set; }

enum CertmgrCertStoreTypes { cstUser, cstMachine, cstPFXFile, cstPFXBlob, cstJKSFile, cstJKSBlob, cstPEMKeyFile, cstPEMKeyBlob, cstPublicKeyFile, cstPublicKeyBlob, cstSSHPublicKeyBlob, cstP7BFile, cstP7BBlob, cstSSHPublicKeyFile, cstPPKFile, cstPPKBlob, cstXMLFile, cstXMLBlob, cstJWKFile, cstJWKBlob, cstSecurityKey, cstBCFKSFile, cstBCFKSBlob, cstAuto }

Default Value

0

Remarks

The component supports both public and private keys in a variety of formats. When the cstAuto value is used the component will automatically determine the type. This field can take one of the following values:

0 (cstUser - default)For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
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.
4 (cstJKSFile)The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
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.
11 (cstP7BFile)The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)The certificate store is a string that contains a JWK (JSON Web Key).
20 (cstSecurityKey)The certificate is present on a physical security key accessible via a PKCS11 interface.

To use a security key the necessary data must first be collected using the CertMgr component. The ListStoreCertificates method may be called after setting CertStoreType to cstSecurityKey, CertStorePassword to the PIN, and CertStore to the full path of the PKCS11 dll. The certificate information returned in the CertList event's CertEncoded parameter may be saved for later use.

When using a certificate, pass the previously saved security key information as the Store and set StorePassword to the PIN.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstSecurityKey; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstSecurityKey, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.

Default Value

""

Remarks

This property holds the exported certificate if it was not exported to a file.

When calling ExportCertificate if the CertFile parameter is an empty string, the certificate will be exported as a string and available in this property. This allows certificate data to be exported without writing any data to disk.

When ExportFormat is set to PFX or P7B, the EncodeExportedCert setting controls whether the value is binary or Base64 encoded.

This property is read-only and not available at design time.

ExportFormat Property (CertMgr Component)

This is the format to which the certificate is exported.

Syntax

public string ExportFormat { get; set; }
Public Property ExportFormat As String

Default Value

"PFX"

ExportPrivateKey Property (CertMgr Component)

This controls whether to export the private key.

Syntax

public bool ExportPrivateKey { get; set; }
Public Property ExportPrivateKey As Boolean

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.

Config Method (CertMgr Component)

Sets or retrieves a configuration setting.

Syntax

public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);
Public Function Config(ByVal ConfigurationString As String) As String

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)

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 displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
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 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);

Async Version
Public Sub ExportCertificate(ByVal CertFile As String, ByVal Password As String) As Task
Public Sub ExportCertificate(ByVal CertFile As String, ByVal Password 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.

ExportFormatApplicabilityDescription
"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.

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 displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail 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", "", "*");

ImportSignedCSR Method (CertMgr Component)

Public Sub IssueCertificate(ByVal CertSubject As String, ByVal SerialNumber As Integer, cancellationToken As CancellationToken) As Task

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 displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
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 component will be used as the issuing certificate.

If no certificate has been selected in the current CertStore before calling this method, or if the selected certificate does not have an associated private key, the method throws an exception.

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.

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CyrptoAPI option. The default value is True (the key is persisted). "Thumbprint" - a MD5, SHA1, or SHA256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, byte[] encoded);
Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Encoded As Byte())

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject);
Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal StoreBlob As Byte(), ByVal StorePassword As String, ByVal Subject As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject, string configurationString);
Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal StoreBlob As Byte(), ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X509 certificate's subject Distinguished Name (DN).

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, byte[] encoded);
Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal StoreBlob As Byte(), ByVal StorePassword As String, ByVal Encoded As Byte())

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a string (binary- or base64-encoded) containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will load Encoded as an X509 certificate and search the opened store for a corresponding private key.

Configuration 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 Configuration Settings

CertComment:   A comment to include in a saved certificate.

This settings specifies the certificate comment when calling ExportCertificate. This setting is applicable only when ExportFormat is set to one of the following values:

When ExportFormat is set to SSH2PublicKey, the value of this setting must be the full header (e.g., Comment: My Comment).
CertExtendedKeyUsage:   The extended key usage of the certificate.

This setting specifies the extended key usage flags of the certificate created by calling CreateCertificate or IssueCertificate. If specified, the value is a comma-separated list of OIDs. Common OIDs are as follows:

1.3.6.1.5.5.7.3.1 Server Authentication
1.3.6.1.5.5.7.3.2 Client Authentication
1.3.6.1.5.5.7.3.3 Code Signing

1.3.6.1.5.5.7.3.8 Time Stamping
1.3.6.1.5.5.7.3.9 OCSP Signing

For instance, the following value specified the extended key usage for Server Authentication, Client Authentication, and Code Signing: 1.3.6.1.5.5.7.3.1, 1.3.6.1.5.5.7.3.2, and 1.3.6.1.5.5.7.3.3

CertKeyLength:   The public key length for created certificates and keys.

When CreateCertificate creates a new certificate and associated key, or when CreateKey creates a key, this setting determines the length of the new public key (in bits). The default value is 2048.

CertKeyType:   The types of keys created for new certificates.

When CreateCertificate creates a new certificate and associated key, or when CreateKey creates a key, this setting determines the type of key generated: 1 for key exchange (encryption) keys, and 2 for digital signature keys. The default value is 1.

CertPublicKeyAlgorithm:   The public key algorithm used when a certificate is created.

When CreateCertificate creates a new certificate and associated key, this setting determines the public key algorithm of the generated keys. Following are the valid values:

  • RSA (default)
  • DSA
  • ECDSA_P256
  • ECDSA_P384
  • ECDSA_P521
  • ECDSA_Secp256k1
  • ECDSA_Secp224k1
  • ECDSA_Secp192k1
  • ECDSA_Secp160k1
  • Ed25519
  • Ed448

CertSignatureAlgorithm:   The signature algorithm used when creating certificates.

When CreateCertificate or IssueCertificate creates a new certificate, the signature algorithm used is specified by this setting. Following are the possible values:

  • MD2
  • MD5
  • SHA1
  • SHA256 (default)
  • SHA384
  • SHA512

CertSubjectAltNames:   Subject Alternative Names for creating or issuing certificates.

This allows the Subject Alternative Names extension to be specified when creating or issuing a certificate via CreateCertificate or IssueCertificate. This setting only supports email, DNS, URI, and IPv4 addresses. Separate alternative names should be separated by commas. For example:

string altNames = "email:copy,dns:domain.com,dns.1:other.domain.com,uri:http://www.domain.com,ip:192.168.1.102"

CertUsageFlags:   Sets the flags indicating the usage of the created certificate.

This setting specifies the usage flags of the certificate created by calling CreateCertificate or IssueCertificate. If specified, the value is the binary or one or more of the supported values. For instance a value of 12 or 0xC is the binary or is one of the Certificate Signing and Key Signing usage flags. Following are the supported flags:

0x80 Digital Signatures
0x40 Key Authentication
0x20 Key Encryption
0x10 Data Encryption
0x08 Key Agreement
0x04 Certificate Signing
0x02 Key Signing

CertValidityOffset:   The number of days until the certificate becomes valid.

This configuration setting can be used to change when a newly created certificate becomes valid. By default, the certificate is valid as soon as it is created. Set CertValidityOffset to the number of days that this starting period should be offset from the current day. This setting also accepts negative values for back-dating the validity of a certificate. The default value is 0.

CertValidityTime:   The validity period for the certificate.

This configuration setting determines the duration in days that a newly created certificate remains valid. The certificate becomes valid as soon as it is created, unless CertValidityOffset is set. The duration is not changed if CertValidityOffset is set; the certificate will still expire CertValidityTime days after the validity period begins. The default value is 365 days.

CreatedKey:   The PKCS8 formatted private and public key pair created after calling CreateKey.

This setting returns the PKCS8 formatted private and public key pair of the key created when CreateKey is called. This is useful in scenarios where exporting the key for use in another environment is required.

CSP:   The Cryptographic Service Provider.

The name of the Cryptographic Service Provider used to provide access to certificate signing operations.

CSRKey:   The PKCS8 formatted private key to use when generating a CSR.

This setting optionally specifies a PKCS8 formatted private key to use when calling GenerateCSR. When set, the keyName parameter of GenerateCSR is ignored and the key specified by this setting is used instead.

EncodeExportedCert:   Whether the certificate being exported to a string is encoded.

This setting controls whether the certificate exported as a string when ExportCertificate is called is encoded. If ExportFormat is set to PFX or P7B before calling ExportCertificate the exported certificate may be binary (EncodeExportedCert is False), or base64 encoded (EncodeExportedCert is True) to allow easier handling of the certificate data.

The default value is False.

ImportCertAction:   Specified the action to take if a matching certificate or a link to a matching certificate already exists.

When calling ImportCertificate if a matching certificate or a link to a matching certificate already exists in the Windows certificate store this setting governs what action will be taken. Possible values are:

1CERT_STORE_ADD_NEW - Imports a certificate only if no existing certificate is present.
2CERT_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.
4CERT_STORE_ADD_ALWAYS - No checks are performed and a new certificate is always added to the store. This can result in duplicates.
5CERT_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.
6CERT_STORE_ADD_NEWER - Imports a certificate only if the certificate is newer than an existing matching certificate.
7CERT_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.

ImportCertStoreType:   The type of certificate store being specified for import.

When calling ImportCertificate, this setting controls the type of the certificate being specified in the first parameter.

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.

Note that this functionality is currently for Windows platforms only.

JWKAlgorithm:   The JWK algorithm.

This setting specifies the JWK algorithm. It can be set before calling ExportCertificate (if ExportFormat is set to JWK) to control the key algorithm used to create the JWK. This setting will also be populated after loading a JWK file.

Valid values are:

  • (empty string)
  • HS256
  • HS384
  • HS512
  • RS256
  • RS384
  • RS512
  • EC256
  • EC384
  • EC512
  • EC256K

JWKExportX5C:   Whether to export a certificate chain to the x5c parameter.

When set to true, the component will attempt to build the X.509 certificate chain for the certificate currently selected by Cert. If successful, the x5c parameter will be added to the JWK. It can be set before calling ExportCertificate (if ExportFormat is set to JWK).

The default value is False.

JWKKeyId:   The JWK key Id.

This setting specifies the JWK key Id. It can be set before calling ExportCertificate (if ExportFormat is set to JWK). This setting will also be populated after loading a JWK file.

JWKKeyOps:   The JWK intended key operations list.

This setting specifies the intended key operations for the JWK. It can be set before calling ExportCertificate (if ExportFormat is set to JWK). This setting will also be populated after loading a JWK file.

This setting format is a JSON array. Examples: ["sign","verify"] or ["encrypt"].

JWKUse:   The JWK use parameter value.

This setting specifies the intended usage of the key. It can be set before calling ExportCertificate (if ExportFormat is set to JWK). This setting will also be populated after loading a JWK file.

Valid values are enc and sig.

KeyFormat:   How the public and private key are formatted.

This setting controls the format of PublicKey and PrivateKey. By default these fields hold PEM formatted public and private key data. When set to 1 (XML) the keys are stored in a XML format. This only affects the values returned by the component; the actual keys remain the same regardless of this setting. Possible values are:

  • 0 (PEM - default)
  • 1 (XML)
The default value is 0 (PEM).
LogLevel:   The level of detail that is logged.

This setting controls the level of detail that is logged through the Log event. Possible values are:

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.

ReplaceKey:   Whether or not to replace an existing key when creating a new key.

If this is false (default), the component will throw an error if a duplicate key exists while generating a new keyset using CreateKey. If set to true, the component will replace a key if it already exists when generating new keys.

RequestSubjectAltNames:   Subject Alternative Names for a Certificate Signing Request.

This allows Subject Alternative Names to be added to a Certificate Signing request. The setting only supports email, DNS, URI, and IPv4 addresses. Separate alternative names should be separated by commas. For example:

string altNames = "email:copy,dns:domain.com,dns.1:other.domain.com,uri:http://www.domain.com,ip:192.168.1.102"

X509Algorithm:   Public Key Algorithm OID.

This setting exposes the Public Key Algorithm object identifier (OID) value for the currently loaded Cert.

X509SignatureAlgorithm:   Signature Algorithm OID.

This setting exposes the Signature Algorithm object identifier (OID) value for the currently loaded Cert.

Base Configuration Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable:   Tells the component whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The component will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

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.

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a component is using. It will return the following information:

  • 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).
UseInternalSecurityAPI:   Tells the component whether or not to use the system security libraries or an internal implementation.

By default the component will use the system security libraries to perform cryptographic functions. When set to False calls to unmanaged code will be made. In certain environments this is not desirable. To use a completely managed security implementation set this setting to True. Setting this to True tells the component to use the internal implementation instead of using the system's security API.

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 DLL is no longer required as a reference, as all unmanaged code is stored in that file.
