CertChain PHP Extension Reference Documentation

CkCertChain

Current Version: 10.1.2

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

Object Creation

$obj = new CkCertChain();

Properties

DebugLogFilePath
string debugLogFilePath();
void put_DebugLogFilePath(string 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
(read-only)
string 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
(read-only)
string 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
(read-only)
string 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
bool get_LastMethodSuccess()
void put_LastMethodSuccess(bool boolVal);

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.

top
NumCerts
(read-only)
int get_NumCerts()
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.

top
NumExpiredCerts
(read-only)
int get_NumExpiredCerts()
Introduced in version 9.5.0.40

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

top
ReachesRoot
(read-only)
bool get_ReachesRoot()
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.

top
UncommonOptions
string uncommonOptions();
void put_UncommonOptions(string strVal);
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.

top
Utf8
bool get_Utf8()
void put_Utf8(bool boolVal);

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

top
VerboseLogging
bool get_VerboseLogging()
void put_VerboseLogging(bool boolVal);

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
(read-only)
string version();

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

Methods

GetCert
CkCert GetCert(int index);
Introduced in version 9.5.0.40

Returns the Nth certificate in the chain.

Returns null on failure

top
IsRootTrusted
bool IsRootTrusted(CkTrustedRoots trustedRoots);
Introduced in version 9.5.0.40

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

top
LoadX5C
bool LoadX5C(CkJsonObject 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.

top
VerifyCertSignatures
bool VerifyCertSignatures();
Introduced in version 9.5.0.40

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

top
X509PKIPathv1
bool X509PKIPathv1(CkString outStr);
string x509PKIPathv1();
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.
