CertChain Unicode C++ Reference Documentation

CkCertChainW

Current Version: 10.1.2

Contains certificates in a chain of authentication to a trusted root.

Object Creation

// Local variable on the stack
CkCertChainW obj;

// Dynamically allocate/delete
CkCertChainW *pObj = new CkCertChainW();
// ...
delete pObj;

Properties

DebugLogFilePath

void get_DebugLogFilePath(CkString &str);
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);

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.

LastErrorHtml

void get_LastErrorHtml(CkString &str);
const wchar_t *lastErrorHtml(void);

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.

LastErrorText

void get_LastErrorText(CkString &str);
const wchar_t *lastErrorText(void);

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.

LastErrorXml

void get_LastErrorXml(CkString &str);
const wchar_t *lastErrorXml(void);

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.

LastMethodSuccess

bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicates the success or failure of the most recent method call: true means success, false 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.

NumCerts

int get_NumCerts(void);

Introduced in version 9.5.0.40

The number of certificates in the chain. The end-user subscriber certificate is at index 0. This is the certificate most removed from the trusted root. Intermediate certificates are at indices 1 to NumCerts - 2. The trusted root (or self-signed certificate) is at index NumCerts - 1.

NumExpiredCerts

int get_NumExpiredCerts(void);

Introduced in version 9.5.0.40

Returns the number of certificates in the chain that have expired.

ReachesRoot

bool get_ReachesRoot(void);

Introduced in version 9.5.0.44

true if this certificate chain extends all the way to the root certificate. The root certificate is either a trusted CA root or a self-signed certificate. In both cases, the issuer of a root certificate is itself.

UncommonOptions

void get_UncommonOptions(CkString &str);
const wchar_t *uncommonOptions(void);
void put_UncommonOptions(const wchar_t *str);

Introduced in version 9.5.0.98

Can be set to a comma separated list of keywords to specify uncommon options. The current uncommon options are:

PkiPathV1.ExcludeRoot Exclude the root certificate in the X509PKIPathv1 method.

VerboseLogging

bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

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

void get_Version(CkString &str);
const wchar_t *version(void);

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

Methods

GetCert

CkCertW *GetCert(int index);

Introduced in version 9.5.0.40

Returns the Nth certificate in the chain.

Note: The application is responsible for deleting (via the C++ delete operator) the object returned by this method.

Returns NULL on failure

IsRootTrusted

bool IsRootTrusted(CkTrustedRootsW &trustedRoots);

Introduced in version 9.5.0.40

Returns true if the root of the certificate chain is a certificate found in trustedRoots.

LoadX5C

bool LoadX5C(CkJsonObjectW &jwk);

Introduced in version 9.5.0.66

Loads a certificate chain from the "x5c" parameter of a JWK (JSON Web Key).

Returns true for success, false for failure.

VerifyCertSignatures

bool VerifyCertSignatures(void);

Introduced in version 9.5.0.40

Verifies the certificate signatures to the root. Returns true if all certificate signatures are valid.

X509PKIPathv1

bool X509PKIPathv1(CkString &outStr);
const wchar_t *x509PKIPathv1(void);

Introduced in version 9.5.0.88

Returns the base64 representation of an X509PKIPathv1 containing the certificates in this chain. This is typically used in an X.509 Binary Security Token. It is a PKIPath that contains an ordered list of X.509 public certificates packaged in a PKIPath. The X509PKIPathv1 token type may be used to represent a certificate path. (This is sometimes used in XAdES signatures.)

Returns true for success, false for failure.
