Csr Delphi DLL Reference Documentation

Csr

Current Version: 10.1.0

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

var
myObject: HCkCsr;

begin
myObject := CkCsr_Create();

// ...

CkCsr_Dispose(myObject);
end;
function CkCsr_Create: HCkCsr; stdcall;

Creates an instance of the HCkCsr object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkCsr_Dispose(handle: HCkCsr); stdcall;

Objects created by calling CkCsr_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

CommonName
procedure CkCsr_getCommonName(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putCommonName(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__commonName(objHandle: HCkCsr): PWideChar; stdcall;
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.

See the notes about PWideChar memory ownership and validity.

procedure CkCsr_getCompany(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putCompany(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__company(objHandle: HCkCsr): PWideChar; stdcall;
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.

See the notes about PWideChar memory ownership and validity.

top
CompanyDivision
procedure CkCsr_getCompanyDivision(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putCompanyDivision(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__companyDivision(objHandle: HCkCsr): PWideChar; stdcall;
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.

See the notes about PWideChar memory ownership and validity.

top
Country
procedure CkCsr_getCountry(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putCountry(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__country(objHandle: HCkCsr): PWideChar; stdcall;
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.

DebugLogFilePath
procedure CkCsr_getDebugLogFilePath(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putDebugLogFilePath(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__debugLogFilePath(objHandle: HCkCsr): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

LastErrorHtml
procedure CkCsr_getLastErrorHtml(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
function CkCsr__lastErrorHtml(objHandle: HCkCsr): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastErrorText
procedure CkCsr_getLastErrorText(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
function CkCsr__lastErrorText(objHandle: HCkCsr): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastErrorXml
procedure CkCsr_getLastErrorXml(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
function CkCsr__lastErrorXml(objHandle: HCkCsr): PWideChar; stdcall;

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.

See the notes about PWideChar memory ownership and validity.

top
LastMethodSuccess
function CkCsr_getLastMethodSuccess(objHandle: HCkCsr): wordbool; stdcall;
procedure CkCsr_putLastMethodSuccess(objHandle: HCkCsr; newPropVal: wordbool); stdcall;

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
procedure CkCsr_getLocality(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putLocality(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;

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.

See the notes about PWideChar memory ownership and validity.

MgfHashAlg
procedure CkCsr_getMgfHashAlg(objHandle: HCkCsr; outPropVal: HCkString); stdcall;
procedure CkCsr_putMgfHashAlg(objHandle: HCkCsr; newPropVal: PWideChar); stdcall;
function CkCsr__mgfHashAlg(objHandle: HCkCsr): PWideChar; stdcall;
Introduced in version 9.5.0.83

If the private key is RSA and PssPadding equals True (RSASSA-PSS padding is used for the RSA signature), then this property controls the MGF hash algorithm used in the RSASSA-PSS padding. The default is "sha256". Can be set to "sha256", "sha384", or "sha512".

See the notes about PWideChar memory ownership and validity.

procedure CkCsr_putPssPadding(objHandle: HCkCsr; newPropVal: wordbool); stdcall;
Introduced in version 9.5.0.83

If _CKTRUE_, and if the private key is RSA, then uses RSASSA-PSS padding for the signature.

top
