Csr Unicode C Reference Documentation

Csr

Current Version: 9.5.0.75

A class for generating Certificate Signing Requests (CSR) or for reading an existing CSR.

This class is introduced in Chilkat v9.5.0.65

Create/Dispose

HCkCsrW instance = CkCsrW_Create();
// ...
CkCsrW_Dispose(instance);
HCkCsrW CkCsrW_Create(void);

Creates an instance of the HCkCsrW object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.

void CkCsrW_Dispose(HCkCsrW handle);

Objects created by calling CkCsrW_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkCsrW_Dispose.

Properties

CommonName
void CkCsrW_getCommonName(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putCommonName(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_commonName(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The common name of the certificate to be generated. For SSL/TLS certificates, this would be the domain name. For email certificates this would be the email address.

It is the value for "CN" in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.3")

This property is required for a CSR.

top
Company
void CkCsrW_getCompany(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putCompany(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_company(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The company or organization name for the certificate to be generated.

It is the value for "O" in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.10")

This property is optional. It may left empty.

top
CompanyDivision
void CkCsrW_getCompanyDivision(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putCompanyDivision(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_companyDivision(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The company division or organizational unit name for the certificate to be generated.

It is the value for "OU" in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.11")

This property is optional. It may left empty.

top
Country
void CkCsrW_getCountry(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putCountry(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_country(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The two-letter uppercase country abbreviation, such as "US", for the certificate to be generated.

It is the value for "C" in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.6")

This property is optional. It may left empty.

top
DebugLogFilePath
void CkCsrW_getDebugLogFilePath(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putDebugLogFilePath(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_debugLogFilePath(HCkCsrW cHandle);

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
EmailAddress
void CkCsrW_getEmailAddress(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putEmailAddress(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_emailAddress(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The email address for the certificate to be generated.

It is the value for "E" in the certificate's Subject's distinguished name (DN). (This is the value for OID "1.2.840.113549.1.9.1")

This property is optional. It may left empty.

top
LastErrorHtml
void CkCsrW_getLastErrorHtml(HCkCsrW cHandle, HCkString retval);
const wchar_t *CkCsrW_lastErrorHtml(HCkCsrW cHandle);

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
void CkCsrW_getLastErrorText(HCkCsrW cHandle, HCkString retval);
const wchar_t *CkCsrW_lastErrorText(HCkCsrW cHandle);

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
void CkCsrW_getLastErrorXml(HCkCsrW cHandle, HCkString retval);
const wchar_t *CkCsrW_lastErrorXml(HCkCsrW cHandle);

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 CkCsrW_getLastMethodSuccess(HCkCsrW cHandle);
void CkCsrW_putLastMethodSuccess(HCkCsrW cHandle, BOOL newVal);
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
Locality
void CkCsrW_getLocality(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putLocality(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_locality(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The locality (city or town) name for the certificate to be generated.

It is the value for "L" in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.7")

This property is optional. It may left empty.

top
State
void CkCsrW_getState(HCkCsrW cHandle, HCkString retval);
void CkCsrW_putState(HCkCsrW cHandle, const wchar_t *newVal);
const wchar_t *CkCsrW_state(HCkCsrW cHandle);
Introduced in version 9.5.0.65

The state or province for the certificate to be generated.

It is the value for "S" (or "ST") in the certificate's Subject's distinguished name (DN). (This is the value for OID "2.5.4.8")

This property is optional. It may left empty.

top
VerboseLogging
BOOL CkCsrW_getVerboseLogging(HCkCsrW cHandle);
void CkCsrW_putVerboseLogging(HCkCsrW cHandle, 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.

top
Version
void CkCsrW_getVersion(HCkCsrW cHandle, HCkString retval);
const wchar_t *CkCsrW_version(HCkCsrW cHandle);

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