CertMgr Component

Properties   Methods   Events   Config Settings   Errors  

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

Syntax

TipqCertMgr

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 CertSubject, CertSerialNumber, and CertIssuer properties identify the certificate. The CertEffectiveDate and CertExpirationDate show the time boundaries of the certificate.

CertPublicKey, CertPublicKeyAlgorithm, CertPublicKeyLength, and CertVersion provide information about the certificate keys and the certificate format (version).

CertUsageFlags specifies the intended usage of the certificate. The CertUsage property provides a text description of these flags.

Cert Property (CertMgr Component)

This is the currently selected certificate.

Syntax

property Cert: TipqCertificate read get_Cert write set_Cert;

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

property CertExtensions: TipqCertExtensionList read get_CertExtensions write set_CertExtensions;

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

property CertStore: String read get_CertStore write set_CertStore;
property CertStoreB: TBytes read get_CertStoreB write set_CertStoreB;

Default Value

'MY'

Remarks

The name of the certificate store for the client certificate.

The StoreType property denotes the type of the certificate store specified by Store. If the store is password-protected, specify the password in StorePassword.

Store is used in conjunction with the Subject property to specify client certificates. If Store has a value, and Subject or Encoded is set, a search for a certificate is initiated. Please see the Subject property for details.

Designations of certificate stores are platform dependent.

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

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

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

ExportedCert Property (CertMgr Component)

This is the exported certificate string.

Syntax

property ExportedCert: String read get_ExportedCert;
property ExportedCertB: TBytes read get_ExportedCertB;

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

property ExportFormat: String read get_ExportFormat write set_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 Component)

This controls whether to export the private key.

Syntax

property ExportPrivateKey: Boolean read get_ExportPrivateKey write set_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.

CheckCRL Method (CertMgr Component)

This method checks the Certificate Revocation List (CRL) specified by the currently loaded certificate.

Syntax

procedure CheckCRL();

Remarks

This method will check the CRLs specified by the currently loaded Cert.

The component will first obtain the list of CRL URLs from the certificate's CRL distribution points extension. The component will then make HTTP requests to each CRL endpoint to check the validity of the certificate.

If the certificate has been revoked or any other issues are found during validation, the component raises an exception. To check whether the certificate supports the CRL extension, use the HasCRL configuration setting.

CheckOCSP Method (CertMgr Component)

This method uses Online Certificate Status Protocol (OCSP) to check the status of the currently loaded certificate.

Syntax

procedure CheckOCSP();

Remarks

This method will use OCSP to check the validity of the currently loaded Cert.

The component will first obtain the OCSP URL from the certificate's OCSP extension. The component will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the certificate.

If the certificate has been revoked or any other issues are found during validation, the component raises an exception. To check whether the certificate supports the OCSP extension, use the HasOCSP configuration setting.

Config Method (CertMgr Component)

Sets or retrieves a configuration setting.

Syntax

function Config(ConfigurationString: String): 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

procedure CreateCertificate(CertSubject: String; SerialNumber: Integer);

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.

In the Unix edition of the toolkit, the certificate will be created in memory. Call ExportCertificate to export the newly created certificate to a PEM file.

CreateKey Method (CertMgr Component)

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

Syntax

procedure CreateKey(KeyName: String);

Remarks

This method will create a new keyset (public/private key pair) within the Cryptographic Service Provider (CSP) used by the component. The CSP can be set using the CSP configuration setting.

Note: This functionality is only available in Windows.

DeleteCertificate Method (CertMgr Component)

This method deletes the currently selected certificate from the store.

Syntax

procedure 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 Component)

This method deletes the keyset associated with the provided name.

Syntax

procedure DeleteKey(KeyName: String);

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 Component)

This method exports the currently selected certificate.

Syntax

procedure ExportCertificate(CertFile: String; Password: String);

Remarks

This method exports the certificate currently selected by CertSubject 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 Component)

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

Syntax

function GenerateCSR(CertSubject: String; KeyName: String): String;

Remarks

This method will generate a new CSR to be sent to the signing authority. CertSubject specifies the subject of the CSR. KeyName specifies the name of the keyset (public/private key pair) to be used. If the keyset does not already exist in the Cryptographic Service Provider (CSP), the component will automatically generate one. To set the CSP, use the CSP configuration setting.

Note: Remember the name of the keyset that is used when creating a CSR. The keyset must be re-associated with the certificate after the trust authority has signed the CSR.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

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

procedure ImportCertificate(CertFile: String; Password: String; Subject: String);

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 raises 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)

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

Syntax

procedure ImportSignedCSR(SignedCSR: TBytes; KeyName: String);

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 Component)

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

Syntax

procedure IssueCertificate(CertSubject: String; SerialNumber: Integer);

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 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 raises 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 Component)

This lists the certificate stores.

Syntax

function ListCertificateStores(): String;

Remarks

This method lists the system certificate stores for the current user account. The results are provided through the StoreList event.

The same information is also returned upon method completion as a set of lines and is given one per certificate store name.

Note: This functionality is only available in Windows.

ListKeys Method (CertMgr Component)

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

Syntax

function ListKeys(): String;

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 Component)

This lists the machine certificate stores.

Syntax

function ListMachineStores(): String;

Remarks

This method behaves the same as the ListCertificateStores method, but it lists the certificate stores in the machine account (under HKEY_LOCAL_MACHINE in the registry).

Note: This functionality is only available in Windows.

ListStoreCertificates Method (CertMgr Component)

This lists the certificates in a store.

Syntax

function ListStoreCertificates(): String;

Remarks

This method lists the certificates in a store. The results are provided through the CertList event.

The same information is also returned upon method completion as a set of lines and is given one per certificate, with each line containing the following information separated by Tab characters: CertSubject, CertIssuer, CertSerialNumber, and HasPrivateKey (as "1" or "0").

In the Unix edition of the toolkit, this is available only when a PFX file is loaded.

ReadCertificate Method (CertMgr Component)

This loads a certificate from a file.

Syntax

procedure ReadCertificate(FileName: String);

Remarks

Note: This method is present for backward compatibility. It is recommended to specify the Cert property to load a certificate.

This method will load a certificate from a file. The file contents can be encoded in Base64 PEM or ASN DER format.

ReadCSR Method (CertMgr Component)

This reads a Certificate Signing Request (CSR).

Syntax

function ReadCSR(CSR: String): String;

Remarks

This method reads a CSR and returns a string holding information about the CSR. The Cert property is also populated with relevant information about the CSR, including the following:

• CertSubject
• CertPublicKeyLength
• CertPublicKeyAlgorithm

The return value will be in the following format:

Reset Method (CertMgr Component)

This resets all certificate properties to their default values.

Syntax

procedure 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 Component)

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

Syntax

procedure SaveCertificate(FileName: String);

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 Component)

This shows the certificate chain.

Syntax

function ShowCertificateChain(): String;

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 Component)

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

Syntax

function SignCSR(CSR: TBytes; SerialNumber: Integer): String;

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 Component)

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

Syntax

type TCertChainEvent = procedure (
  Sender: TObject;
  const CertEncoded: String;
  const CertEncodedB: TBytes;
  const CertSubject: String;
  const CertIssuer: String;
  const CertSerialNumber: String;
  TrustStatus: Integer;
  TrustInfo: Integer
) of Object;

property OnCertChain: TCertChainEvent read FOnCertChain write FOnCertChain;

Remarks

This event is fired for every certificate in the certificate chain of the certificate assigned to the component.

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 Component)

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

Syntax

type TCertListEvent = procedure (
  Sender: TObject;
  const CertEncoded: String;
  const CertEncodedB: TBytes;
  const CertSubject: String;
  const CertIssuer: String;
  const CertSerialNumber: String;
  HasPrivateKey: Boolean
) of Object;

property OnCertList: TCertListEvent read FOnCertList write FOnCertList;

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 Component)

Fired when information is available about errors during data delivery.

Syntax

type TErrorEvent = procedure (
  Sender: TObject;
  ErrorCode: Integer;
  const Description: String
) of Object;

property OnError: TErrorEvent read FOnError write FOnError;

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises 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 Component)

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

Syntax

type TKeyListEvent = procedure (
  Sender: TObject;
  const KeyContainer: String;
  KeyType: Integer;
  const AlgId: String;
  KeyLen: Integer
) of Object;

property OnKeyList: TKeyListEvent read FOnKeyList write FOnKeyList;

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 Component)

This event fires once for each log message.

Syntax

type TLogEvent = procedure (
  Sender: TObject;
  LogLevel: Integer;
  const Message: String;
  const LogType: String
) of Object;

property OnLog: TLogEvent read FOnLog write FOnLog;

Remarks

This event fires once for each log message generated by the component. 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 Component)

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

Syntax

type TStoreListEvent = procedure (
  Sender: TObject;
  const CertStore: String
) of Object;

property OnStoreList: TStoreListEvent read FOnStoreList write FOnStoreList;

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

constructor Create(valOID: String; valValue: TBytes; valCritical: Boolean);

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
