CertMgr Class

Properties Methods Events Config Settings Errors

The CertMgr class is used to create, read, and manage certificates.

Syntax

ipworksiot.Certmgr

Remarks

The class 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 class. 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 Class)

This is the currently selected certificate.

Syntax


public Certificate getCert();


public void setCert(Certificate cert);

Remarks

This property is populated when a specified certificate is found or loaded by the class. 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.

Please refer to the Certificate type for a complete list of fields.

CertExtensions Property (CertMgr Class)

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

Syntax


public CertExtensionList getCertExtensions();


public void setCertExtensions(CertExtensionList certExtensions);

Remarks

This property contains a list of extensions used by the currently selected certificate. When Cert is set, the class 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.

Please refer to the CertExtension type for a complete list of fields.

CertStore Property (CertMgr Class)

This is the certificate store to search for certificates.

Syntax


public byte[] getCertStore();


public void setCertStore(byte[] certStore);

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


MY	A certificate store holding personal certificates with their associated private keys.
CA	Certifying authority certificates.
ROOT	Root certificates.

In Java, the certificate store normally is a file containing certificates and optional private keys.

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., PKCS#12 certificate store).

CertStorePassword Property (CertMgr Class)

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

Syntax


public String getCertStorePassword();


public void setCertStorePassword(String certStorePassword);

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 Class)

This is the type of certificate store for CertStore .

Syntax


public int getCertStoreType();


public void setCertStoreType(int certStoreType);


Enumerated values:
  public final static int cstUser = 0;

  public final static int cstBCFKSBlob = 22;
  public final static int cstPKCS11 = 23;
  public final static int cstAuto = 99;

Default Value

Remarks

The class supports both public and private keys in a variety of formats. When the cstAuto value is used, the class 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 (PKCS#12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in PFX (PKCS#12) 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 PKCS#7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS#7 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).

22 (cstBCFKSBlob)	The certificate store is a string (binary or Base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: This store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS#11 interface. To use a security key, the necessary data must first be collected using the CertMgr class. The ListStoreCertificates method may be called after setting CertStoreType to `cstPKCS11`, CertStorePassword to the PIN, and CertStore to the full path of the PKCS#11 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.cstPKCS11; 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.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

ExportedCert Property (CertMgr Class)

This is the exported certificate string.

Syntax


public byte[] getExportedCert();

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 Class)

This is the format to which the certificate is exported.

Syntax


public String getExportFormat();


public void setExportFormat(String exportFormat);

Default Value

"PFX"

Remarks

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.

ExportPrivateKey Property (CertMgr Class)

This controls whether to export the private key.

Syntax


public boolean isExportPrivateKey();


public void setExportPrivateKey(boolean exportPrivateKey);

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 Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

CreateCertificate Method (Certmgr Class)

This method creates a new self-signed certificate in the current store.

Syntax

public void createCertificate(String certSubject, int serialNumber);

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 Class)

This method creates a new keyset associated with the provided name.

Syntax

public void createKey(String keyName);

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.

DeleteCertificate Method (Certmgr Class)

This method deletes the currently selected certificate from the store.

Syntax

public void deleteCertificate();

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.

DeleteKey Method (Certmgr Class)

This method deletes the keyset associated with the provided name.

Syntax

public void deleteKey(String keyName);

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.

ExportCertificate Method (Certmgr Class)

This method exports the currently selected certificate.

Syntax

public void exportCertificate(String certFile, String password);

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.

GenerateCSR Method (Certmgr Class)

This method generates a new Certificate Signing Request (CSR) to be sent to a signing authority.

Syntax

public String generateCSR(String certSubject, String keyName);

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.


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.

public void importCertificate(String certFile, String password, String subject);

Remarks

This method will import a certificate from a file into the current certificate store.

This method imports the PFX (PKCS12) file specified by CertFile to the Java Key Store (JKS) specified by Store.

The Password parameter specifies the certificate password (if any).

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 Class)

This method mports a signed Certificate Signing Request (CSR).

Syntax

public void importSignedCSR(byte[] signedCSR, String keyName);

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.

IssueCertificate Method (Certmgr Class)

This creates a new certificate in the current store and is signed by the selected certificate.

Syntax

public void issueCertificate(String certSubject, int serialNumber);

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.


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 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.

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.

The CertList event and the ListStoreCertificates method are used to list the certificates in the store.

CertExtension Type

This represents an extension for a certificate.

Remarks

A CertExtension represents an extension that adds to or modifies an X509 Certificate. Certificate extensions are defined by their ASN.1 Object-Identifier (OID). The Value field contains the raw data of the extension, which is usually ASN.1 encoded.

Fields

Critical
boolean (read-only)
Default Value: False

This field specifies whether or not the extension is defined as critical.

OID
String (read-only)
Default Value: ""

This field contains the ASN.1 Object-Identifier (OID) that defines this certificate extension.

Value
String (read-only)
Default Value: ""

This field contains the raw value of the certificate extension. This value is encoded according to the extension's ASN.1 specification and should contain everything following the OID. The following example is provided for clarity.

public Certificate( certificateData);

Parses CertificateData as an X509 public key.

public Certificate( certStoreType,  store,  storePassword,  subject);

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 class 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( certStoreType,  store,  storePassword,  subject,  configurationString);

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.

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.

CheckCRL: Checks the Certificate Revocation List for the selected certificate.

When queried, this setting will check the Certificate Revocation List 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 throws an exception.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

CheckOCSP: Uses OCSP to check the status of the selected certificate.

When queried, the class 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 throws an exception.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

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.

HasCRL: Whether the certificate supports the CRL extension.

This setting returns true if the currently loaded Cert supports the CRL extension.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

HasOCSP: Whether the certificate supports the OCSP extension.

This setting returns true if the currently loaded Cert supports the OCSP extension.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

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:


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.

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.

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 class; 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:

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.

RequestExtendedKeyUsage: The extended key usage of the Certificate Signing Request.

This setting specifies the extended key usage flags of the certificate signing request created by calling GenerateCSR. If specified, the value is a comma separated list of OIDs. Common OIDs are:

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"

RequestUsageFlags: Sets the flags indicating the usage of the created Certificate Signing Request.

This setting specifies the usage flags of the certificate signing request created by calling GenerateCSR. If specified, the value is the binary or of one or more supported values.

Base Config Settings

BuildInfo: Information about the product's build.

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

GUIAvailable: 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 class 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 class 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 class 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).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is true.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseDaemonThreads: Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

UseInternalSecurityAPI: Whether or not to use the system security libraries or an internal implementation.

When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this configuration setting to true tells the class to use the internal implementation instead of using the system security libraries.

This setting is set to false by default on all platforms.
