Chilkat_9_5_0.CertStore PHP ActiveX Reference Documentation

Chilkat_9_5_0.CertStore

Current Version: 9.5.0.73

Represents a collection of certificates. The certificates may be loaded from a PFX (PKCS#12) or from a Windows-based certificate store.

Many of the methods of this class are only applicable when running on a MS Windows operating system. The methods for opening, creating, and modifying Windows-based certificate stores (registry-based, file-based, and memory-based) are (of course) Windows-only. However, the methods for loading certs from PFX (PKCS#12), are valid on all supported operating systems, including Linux, MAC OS X, Windows, etc.

Object Creation

$obj = new COM("Chilkat_9_5_0.CertStore");

Properties

AvoidWindowsPkAccess
bool AvoidWindowsPkAccess

Applies only when running on a Microsoft Windows operating system. If true, 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 false.

top
DebugLogFilePath
string DebugLogFilePath

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastBinaryResult
VARIANT LastBinaryResult (read-only)
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to true. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
string LastErrorHtml (read-only)

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
string LastErrorText (read-only)

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
string LastErrorXml (read-only)

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
bool LastMethodSuccess
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = true and failure = false.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
LastStringResult
string LastStringResult (read-only)
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to true. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
int LastStringResultLen (read-only)
Introduced in version 9.5.0.53

The length, in characters, of the string contained in the LastStringResult property.

top
NumCertificates
int NumCertificates (read-only)

The number of certificates held in the certificate store.

top
NumEmailCerts
int NumEmailCerts (read-only)

(This property only available on Microsoft Windows operating systems.)
The number of certificates that can be used for sending secure email within this store.

top
VerboseLogging
bool VerboseLogging

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

top
Version
string Version (read-only)

Version of the component/library, such as "9.5.0.63"

(This method only available on Microsoft Windows operating systems.)
Creates a new file-based certificate store. Certificates may be saved to this store by calling AddCertificate.

Returns true for success, false for failure.

top
CreateMemoryStore
bool CreateMemoryStore()

(This method only available on Microsoft Windows operating systems.)

top
FindCertBySubject
Chilkat_9_5_0.Cert FindCertBySubject(string str)

Finds a certificate where one of the Subject properties (SubjectCN, SubjectE, SubjectO, SubjectOU, SubjectL, SubjectST, SubjectC) matches exactly (but case insensitive) with the passed string. A match in SubjectCN will be tried first, followed by SubjectE, and SubjectO. After that, the first match found in SubjectOU, SubjectL, SubjectST, or SubjectC, but in no guaranteed order, is returned. All matches are case insensitive.

Returns null on failure.
