CertMgr Class

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

ipworkssftp.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.

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.

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:

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);

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

Default Value

0

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:

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.

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:

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.

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.

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.

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:

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

NOTE: This functionality is only available in Windows.

ImportCertificate Method (Certmgr Class)

This method imports a certificate from a file into the current certificate store.

Syntax

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.

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:

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.

NOTE: This functionality is only available in Windows.

ListCertificateStores Method (Certmgr Class)

This lists the certificate stores.

Syntax

public String listCertificateStores();

Remarks

NOTE: This functionality is only available in Windows.

ListKeys Method (Certmgr Class)

This lists the keysets in a Cryptographic Service Provider (CSP).

Syntax

public String listKeys();

Remarks

This method lists the keys (public/private key pairs) in a CSP. The results are provided through the KeyList 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.

ListMachineStores Method (Certmgr Class)

This lists the machine certificate stores.

Syntax

Reset Method (Certmgr Class)

This resets all certificate properties to their default values.

Syntax

public void reset();

Remarks

This method will reset all certificate properties to their default values. If a certificate and a private key are selected or a certificate store is opened, both are released upon calling this method.

SaveCertificate Method (Certmgr Class)

This method saves the currently selected public certificate to a file.

Syntax

public void saveCertificate(String fileName);

Remarks

Note: This method is present for backward compatibility. It is recommended to use ExportCertificate to export both public and private certificates and keys.

This method saves the public certificate of the currently selected certificate in Base64 PEM format to the location specified by the FileName parameter.

If the destination file exists, it is overwritten.

ShowCertificateChain Method (Certmgr Class)

This shows the certificate chain.

Syntax

public String showCertificateChain();

Remarks

This method shows the certificate chain for the certificate. The results are provided through the CertChain 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: CertSubject, CertIssuer, CertSerialNumber, TrustStatus, and TrustInfo.

NOTE: This functionality is only available in Windows.

SignCSR Method (Certmgr Class)

This creates a signed certificate from a Certificate Signing Request (CSR).

Syntax

public String signCSR(byte[] CSR, int serialNumber);

Remarks

This method will create a signed certificate from a CSR. CSR specifies the CSR to be signed.

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 is determined by the CertKeyLength configuration setting.

NOTE: This functionality is only available in Windows.

CertChain Event (Certmgr Class)

This event shows the certificate chain for the certificate (see the ShowCertificateChain method).

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void certChain(CertmgrCertChainEvent e) {}
  ...
}

public class CertmgrCertChainEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String certSerialNumber;
  public int trustStatus;
  public int trustInfo;
}

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:

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:

The CertSubject and CertIssuer parameters contain the distinguished names of the certificate owner and issuer, respectively.

CertList Event (Certmgr Class)

This event lists the certificates in a store (see the ListStoreCertificates method).

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void certList(CertmgrCertListEvent e) {}
  ...
}

public class CertmgrCertListEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String certSerialNumber;
  public boolean hasPrivateKey;
}

Remarks

The CertSubject and CertIssuer parameters contain distinguished names of the certificate owner and issuer, respectively. The HasPrivateKey flag shows whether the private key for the certificate is available in the system.

The StoreList event and the ListCertificateStores and ListMachineStores methods are used to list the certificate stores in the system.

Error Event (Certmgr Class)

Information about errors during data delivery.

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void error(CertmgrErrorEvent e) {}
  ...
}

public class CertmgrErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

KeyList Event (Certmgr Class)

This lists the keysets in a Cryptographic Service Provider (CSP); see the ListKeys method.

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void keyList(CertmgrKeyListEvent e) {}
  ...
}

public class CertmgrKeyListEvent {
  public String keyContainer;
  public int keyType;
  public String algId;
  public int keyLen;
}

Remarks

The KeyContainer parameter is the name used to identify the keyset (public/private key pair) when it was first created.

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).

Log Event (Certmgr Class)

This event fires once for each log message.

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void log(CertmgrLogEvent e) {}
  ...
}

public class CertmgrLogEvent {
  public int logLevel;
  public String message;
  public String logType;
}

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:

Message is the log entry.

LogType identifies the type of log entry.

StoreList Event (Certmgr Class)

This lists the system certificate stores (see the ListCertificateStores and ListMachineStores methods).

Syntax

public class DefaultCertmgrEventListener implements CertmgrEventListener {
  ...
  public void storeList(CertmgrStoreListEvent e) {}
  ...
}

public class CertmgrStoreListEvent {
  public String certStore;
}

Remarks

The CertStore parameter contains the name of the certificate store being listed.

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

Constructors

public CertExtension( oid,  value,  critical);

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

public Certificate();

Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.

public Certificate( certificateFile);

Opens CertificateFile and reads out the contents as an X509 public key.

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. 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,  encoded);

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 load Encoded as an X509 certificate and search the opened store for a corresponding private key.

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

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 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,  storeBlob,  storePassword,  subject,  configurationString);

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 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,  storeBlob,  storePassword,  encoded);

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 class will load Encoded as an X509 certificate and search the opened store for a corresponding private key.
