Properties

CommonName
Function ComCommonName Returns String
Procedure Set ComCommonName String value
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
Function ComCompany Returns String
Procedure Set ComCompany String value
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
Function ComCompanyDivision Returns String
Procedure Set ComCompanyDivision String value
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
Function ComCountry Returns String
Procedure Set ComCountry String value
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
Function ComDebugLogFilePath Returns String
Procedure Set ComDebugLogFilePath String value

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.

EmailAddress
Function ComEmailAddress Returns String
Procedure Set ComEmailAddress String value
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
HashAlgorithm
Function ComHashAlgorithm Returns String
Procedure Set ComHashAlgorithm String value
Introduced in version 9.5.0.82

The hash algorithm to be used when creating the CSR. The default is SHA256. Can be set to SHA1, SHA384, SHA256, or SHA512.

top
LastBinaryResult
Function ComLastBinaryResult Returns Variant

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to True. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
Function ComLastErrorHtml Returns String

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
Function ComLastErrorText Returns String

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
Function ComLastErrorXml Returns String

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
Function ComLastMethodSuccess Returns Boolean
Procedure Set ComLastMethodSuccess Boolean value

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
LastStringResult
Function ComLastStringResult Returns String

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to True. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
Function ComLastStringResultLen Returns Integer

The length, in characters, of the string contained in the LastStringResult property.

top
Locality
Function ComLocality Returns String
Procedure Set ComLocality String value
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
MgfHashAlg
Function ComMgfHashAlg Returns String
Procedure Set ComMgfHashAlg String value
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".

top
PssPadding
Function ComPssPadding Returns Boolean
Procedure Set ComPssPadding Boolean value
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
State
Function ComState Returns String
Procedure Set ComState String value
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
Function ComVerboseLogging Returns Boolean
Procedure Set ComVerboseLogging Boolean value

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
Function ComVersion Returns String

Version of the component/library, such as "9.5.0.94"

Methods

AddSan
Function ComAddSan String sanType String sanValue Returns Boolean
Introduced in version 9.5.0.84

Adds a SAN value (Subject Alternative Name) to the CSR to be generated. This method can be called multiple times -- one per subject alternative name to be added.
