CertStore

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.

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.

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.

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.

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.

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.

The number of certificates held in the certificate store.

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

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

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

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.

Version of the component/library, such as "9.5.0.94"

(This method only available on Microsoft Windows operating systems.)
Adds a certificate to the store. If the certificate is already in the store, it is updated with the new information.

Returns true for success, false for failure.

(This method only available on Microsoft Windows operating systems.)
Closes the certificate store previously opened by one of the Open* methods.

Returns true for success, false for failure.

(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.

(This method only available on Microsoft Windows operating systems.)
Creates an in-memory certificate store. Certificates may be added by calling AddCertificate.

Returns true for success, false for failure.

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

Returns true for success, false for failure.

Finds a certificate by it's key container name.

Returns null on failure

Locates and returns a certificate by its RFC 822 name.

If multiple certificates match, then non-expired certificates will take precedence over expired certificates. In other words, Chilkat will aways return the non-expired certificate over the expired certificate.

Returns null on failure

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

Returns null on failure.

Returns null on failure

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

Returns null on failure.

Returns null on failure

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.

Returns null on failure

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

Finds a certificate where the SubjectE property (email address) matches exactly (but case insensitive) with the passed string. This function differs from FindCertForEmail in that the certificate does not need to match the ForSecureEmail property.

Returns null on failure.

Returns null on failure

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

(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

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

Returns null on failure.

Returns null on failure

(This method only available on Microsoft Windows operating systems.)
Returns the Nth email certificate in the store. The first certificate is at index 0. Use the NumEmailCertificates property to get the number of email certificates.

Returns null on failure.

Returns null on failure

Loads the certificates contained within a PEM formatted file.

Returns true for success, false for failure.

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

Returns true for success, false for failure.

Loads a PFX from an in-memory image of 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.

Returns true for success, false for failure.

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 true for success, false for failure.

(This method only available on Microsoft Windows operating systems.)
Opens the registry-based local machine certificate store having the path "Software/Chilkat/SystemCertificates". If the certificate store does not exist, it is automatically created. Setting readOnly = true 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 true for success, false for failure.

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