CertStore Perl Reference Documentation

CkCertStore

Current Version: 10.1.0

Represents a collection of certificates that can be loaded from various sources, including:

  • .pfx or .p12 file containing certificates and private keys.
  • PEM file containing multiple certificates and keys.
  • Windows Certificate Store
  • Apple Keychain (starting in version Chilkat v10.0.0)
  • Connected Smartcards and USB Tokens

Object Creation

$obj = chilkat::CkCertStore->new();

Properties

AvoidWindowsPkAccess
# $boolVal is a boolean
$boolVal = $certStore->get_AvoidWindowsPkAccess();
$certStore->put_AvoidWindowsPkAccess($boolVal);

Applies only when running on a Microsoft Windows operating system. If 1, then any method that returns a certificate will not try to also access the associated private key, assuming one exists. This is useful if the certificate was installed with high-security such that a private key access would trigger the Windows OS to display a security warning dialog. The default value of this property is 0.

DebugLogFilePath
# $strVal is a string
# $ckStr is a CkString
$certStore->get_DebugLogFilePath($ckStr);
$strVal = $certStore->debugLogFilePath();
$certStore->put_DebugLogFilePath($strVal);

If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.

Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.

Possible causes of hangs include:

  • A timeout property set to 0, indicating an infinite timeout.
  • A hang occurring within an event callback in the application code.
  • An internal bug in the Chilkat code causing the hang.

More Information and Examples
top
LastErrorHtml
# $strVal is a string
# $ckStr is a CkString
$certStore->get_LastErrorHtml($ckStr);
$strVal = $certStore->lastErrorHtml();

Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorText
# $strVal is a string
# $ckStr is a CkString
$certStore->get_LastErrorText($ckStr);
$strVal = $certStore->lastErrorText();

Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastErrorXml
# $strVal is a string
# $ckStr is a CkString
$certStore->get_LastErrorXml($ckStr);
$strVal = $certStore->lastErrorXml();

Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.

top
LastMethodSuccess
# $boolVal is a boolean
$boolVal = $certStore->get_LastMethodSuccess();
$certStore->put_LastMethodSuccess($boolVal);

Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.

top
NumCertificates
# $intVal is an integer
$intVal = $certStore->get_NumCertificates();

The number of certificates held in the certificate store.

top
SmartCardPin
# $strVal is a string
# $ckStr is a CkString
$certStore->get_SmartCardPin($ckStr);
$strVal = $certStore->smartCardPin();
$certStore->put_SmartCardPin($strVal);
Introduced in version 9.5.0.86

Can be set to the PIN value for a certificate / private key stored on a smart card.

top
UncommonOptions
# $strVal is a string
# $ckStr is a CkString
$certStore->get_UncommonOptions($ckStr);
$strVal = $certStore->uncommonOptions();
$certStore->put_UncommonOptions($strVal);
Introduced in version 9.5.0.87

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string, and should typically remain empty.

top
Utf8
# $boolVal is a boolean
$boolVal = $certStore->get_Utf8();
$certStore->put_Utf8($boolVal);

When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.

top
VerboseLogging
# $boolVal is a boolean
$boolVal = $certStore->get_VerboseLogging();
$certStore->put_VerboseLogging($boolVal);

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
# $strVal is a string
# $ckStr is a CkString
$certStore->get_Version($ckStr);
$strVal = $certStore->version();

Version of the component/library, such as "10.1.0"

Methods

AddCertificate
# $cert is a CkCert
$status = $certStore->AddCertificate($cert);

On Windows, this updates or adds cert to the open Windows certificate store.

Beginning with Chilkat v10.0.0, on macOS and iOS, this adds the certificate, including any private keys and intermediate CA certificates, to the Apple Keychain.

Returns 1 for success, 0 for failure.

top
CloseCertStore
$status = $certStore->CloseCertStore();
Introduced in version 9.5.0.94

This method closes any open certificate stores, removes all certificates from the object, and sets the NumCertificates property back to 0.

Returns 1 for success, 0 for failure.

top
CreateFileStore
# $filename is a string
$status = $certStore->CreateFileStore($filename);

This method, available only on Microsoft Windows, creates a new file-based certificate store. You can save certificates to this store by using the AddCertificate function.

Internally, the Microsoft function CertOpenStore is called with the provider type CERT_STORE_PROV_FILE and the flag CERT_STORE_CREATE_NEW_FLAG, to create a new, empty certificate store that is backed by a file.

Returns 1 for success, 0 for failure.

top
CreateMemoryStore
$status = $certStore->CreateMemoryStore();

This method, available only on Microsoft Windows, creates an in-memory certificate store. Certificates may be added by calling AddCertificate.

Internally, the Microsoft function CertOpenStore is called with the provider type CERT_STORE_PROV_MEMORY to create a new in-memory certificate store. This store acts as a temporary container for managing certificates during runtime. The store exists only in memory and is not backed by a file or persistent storage. Certificates can be added, retrieved, or removed, but the store is lost when the application ends unless explicitly saved elsewhere.

Returns 1 for success, 0 for failure.

top
CreateRegistryStore
# $regRoot is a string
# $regPath is a string
$status = $certStore->CreateRegistryStore($regRoot, $regPath);

This method, available only on Microsoft Windows, creates a new registry-based certificate store. You can save certificates to this store by using the AddCertificate function.

Internally, the Microsoft function CertOpenStore is called with the provider type CERT_STORE_PROV_REG and a registry key to create a new, empty certificate store in the Windows registry.

regRoot can be the string "CurrentUser" or "LocalMachine". regPath is a registry key path such as "Software/MyApplication/Certificates".

Returns 1 for success, 0 for failure.

top
FindCertBySerial
# returns a CkCert
# $str is a string
$ret_cert = $certStore->FindCertBySerial($str);

Finds and returns the certificate that has the matching serial number.

Returns null on failure.

Returns null on failure

top
FindCertBySha1Thumbprint
# returns a CkCert
# $str is a string
$ret_cert = $certStore->FindCertBySha1Thumbprint($str);

Finds a certificate by it's SHA-1 thumbprint. The thumbprint is a hexidecimal string.

Returns null on failure.

Returns null on failure

top
FindCertBySubjectCN
# returns a CkCert
# $str is a string
$ret_cert = $certStore->FindCertBySubjectCN($str);

Finds a certificate where the SubjectCN property (common name) matches exactly (but case insensitive) with the passed string

Returns null on failure.

Returns null on failure

top
FindCertBySubjectO
# returns a CkCert
# $str is a string
$ret_cert = $certStore->FindCertBySubjectO($str);

Finds a certificate where the SubjectO property (organization) matches exactly (but case insensitive) with the passed string.

Returns null on failure.

Returns null on failure

top
FindCertForEmail
# returns a CkCert
# $emailAddress is a string
$ret_cert = $certStore->FindCertForEmail($emailAddress);

(This method only available on Microsoft Windows operating systems.)
Finds a certificate that can be used to send secure email to the passed email address. A certificate matches only if the ForSecureEmail property is TRUE, and the email address matches exactly (but case insensitive) with the SubjectE property. Returns NULL if no matches are found.

Returns null on failure.

Returns null on failure

top
GetCertificate
# returns a CkCert
# $index is an integer
$ret_cert = $certStore->GetCertificate($index);

Returns the Nth certificate in the store. The first certificate is at index 0.

Returns null on failure.

Returns null on failure

top
LoadPemFile
# $pemPath is a string
$status = $certStore->LoadPemFile($pemPath);

Loads the certificates contained within a PEM formatted file.

Returns 1 for success, 0 for failure.

top
LoadPemStr
# $pemString is a string
$status = $certStore->LoadPemStr($pemString);

Loads the certificates contained within an in-memory PEM formatted string.

Returns 1 for success, 0 for failure.

top
LoadPfxFile
# $pfxFilename is a string
# $password is a string
$status = $certStore->LoadPfxFile($pfxFilename, $password);

Loads a PFX file. Once loaded, the certificates within the PFX may be searched via the Find* methods. It is also possible to iterate from 0 to NumCertficates-1, calling GetCertificate for each index, to retrieve each certificate within the PFX.

Note: This method does not import certificates into the Windows certificate stores. The purpose of this method is to load a .pfx/.p12 into this object so that other API methods can be called to explore or search the contents of the PFX. The Chilkat Pfx class also provides similar functionality.

Returns 1 for success, 0 for failure.

top
OpenCurrentUserStore
# $readOnly is a boolean
$status = $certStore->OpenCurrentUserStore($readOnly);

On Windows, this method opens the Current-User\Personal certificate store in the registry. Set readOnly to 1 to open the store in read-only mode, which allows you to fetch certificates without adding or removing them. This prevents "permission denied" errors that require read-write access.

Starting in version 10.0.0, this method opens the Apple Keychain on MacOS and iOS systems. The readOnly is ignored.

After opening the store, you can search for certificates using the Find* methods. Alternatively, you can iterate through the certificates by indexing from 0 to NumCertificates-1, using GetCertificate to access each one.

Returns 1 for success, 0 for failure.

top
OpenFileStore
# $filename is a string
# $readOnly is a boolean
$status = $certStore->OpenFileStore($filename, $readOnly);

(This method only available on Microsoft Windows operating systems.)
Opens a file-based certificate store.

Once loaded, the certificates within the store may be searched via the Find* methods. An application may also iterate from 0 to NumCertficates-1 and call GetCertificate to access each certificate by index.

Returns 1 for success, 0 for failure.

top
OpenLocalSystemStore
# $readOnly is a boolean
$status = $certStore->OpenLocalSystemStore($readOnly);

(This method is only available on Microsoft Windows operating systems.)
Opens the registry-based Local-Computer\Personal certificate store. Set readOnly = 1 if only fetching certificates and not updating the certificate store (i.e. certificates will not be added or removed). Setting readOnly = 1 causes the certificate store to be opened read-only, and will prevent "permission denied" errors caused by the need for read-write permission.

Once loaded, the certificates within the store may be searched via the Find* methods. An application may also iterate from 0 to NumCertficates-1 and call GetCertificate to access each certificate by index.

Returns 1 for success, 0 for failure.

top
OpenRegistryStore
# $regRoot is a string
# $regPath is a string
# $readOnly is a boolean
$status = $certStore->OpenRegistryStore($regRoot, $regPath, $readOnly);

(This method only available on Microsoft Windows operating systems.)
Opens an arbitrary registry-based certificate store. regRoot must be "CurrentUser" or "LocalMachine". regPath is a registry path such as "Software/MyApplication/Certificates".

Setting readOnly = 1 causes the certificate store to be opened read-only, and will prevent "permission denied" errors caused by the need for read-write permission.

Once loaded, the certificates within the store may be searched via the Find* methods. An application may also iterate from 0 to NumCertficates-1 and call GetCertificate to access each certificate by index.

Returns 1 for success, 0 for failure.

top
OpenSmartcard
# $csp is a string
$status = $certStore->OpenSmartcard($csp);
Introduced in version 9.5.0.80

On Windows, the system utilizes Microsoft CNG and/or CryptoAPI for accessing connected smartcards and USB tokens. For potentially better results, use Cert.LoadFromSmartcard, which can automatically detect and select between PKCS11, ScMinidriver, MS CNG, and MS CryptoAPI. On macOS and iOS, the Apple Keychain is employed.

Note: Chilkat version 10.0.0 and later supports Apple Keychain. csp is deprecated and unused; always pass an empty string for csp.

Returns 1 for success, 0 for failure.

top
OpenWindowsStore
# $storeLocation is a string
# $storeName is a string
# $readOnly is a boolean
$status = $certStore->OpenWindowsStore($storeLocation, $storeName, $readOnly);
Introduced in version 9.5.0.49

(This method only available on Microsoft Windows operating systems.)
Opens a Microsoft Windows certificate store. storeLocation must be "CurrentUser" or "LocalMachine". storeName is the name of the certificate store to open. It may be any of the following:

  • AddressBook: Certificate store for other users.
  • AuthRoot: Certificate store for third-party certification authorities (CAs).
  • CertificationAuthority: Certificate store for intermediate certification authorities (CAs).
  • Disallowed: Certificate store for revoked certificates.
  • My: Certificate store for personal certificates.
  • Root: Certificate store for trusted root certification authorities (CAs).
  • TrustedPeople: Certificate store for directly trusted people and resources.
  • TrustedPublisher: Certificate store for directly trusted publishers.

Setting readOnly = 1 causes the certificate store to be opened read-only, and will prevent "permission denied" errors caused by the need for read-write permission.

Once loaded, the certificates within the store may be searched via the Find* methods. An application may also iterate from 0 to NumCertficates-1 and call GetCertificate to access each certificate by index.

Returns 1 for success, 0 for failure.

top
RemoveCertificate
# $cert is a CkCert
$status = $certStore->RemoveCertificate($cert);

(This method only available on Microsoft Windows operating systems.)
Removes the passed certificate from the store. The certificate object passed as the argument can no longer be used once removed.

Returns 1 for success, 0 for failure.
