CkoCsr Objective-C Reference Documentation

CkoCsr

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

This class is introduced in Chilkat v9.5.0.65

Properties

@property (nonatomic, copy) NSString *CommonName;

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.

@property (nonatomic, copy) NSString *Company;

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.

@property (nonatomic, copy) NSString *CompanyDivision;

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.

@property (nonatomic, copy) NSString *Country;

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.

@property (nonatomic, copy) NSString *DebugLogFilePath;

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.

@property (nonatomic, copy) NSString *EmailAddress;

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.

@property (nonatomic, readonly, copy) NSString *LastErrorHtml;

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.

@property (nonatomic, readonly, copy) NSString *LastErrorText;

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.

Concept of LastErrorText

LastErrorText Standard Information

@property (nonatomic, readonly, copy) NSString *LastErrorXml;

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.

@property (nonatomic) BOOL LastMethodSuccess;

Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of YES indicates success, a value of NO 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 = YES and failure = NO.
  • 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 YES. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

@property (nonatomic, copy) NSString *Locality;

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.

@property (nonatomic, copy) NSString *State;

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.

@property (nonatomic) BOOL VerboseLogging;

If set to YES, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is NO. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

@property (nonatomic, readonly, copy) NSString *Version;

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

Methods

- (BOOL)GenCsrBd:(CkoPrivateKey *)privKey
    csrData:(CkoBinData *)csrData;

Introduced in version 9.5.0.65

Generate a CSR and return the binary DER in csrData.

Returns YES for success, NO for failure.

- (NSString *)GenCsrPem:(CkoPrivateKey *)privKey;

Introduced in version 9.5.0.65
