Csr Swift Reference Documentation

CkoCsr

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

Object Creation

let obj = CkoCsr()!

Properties

CommonName
commonName: String!
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
company: String!
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
companyDivision: String!
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
country: String!
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
debugLogFilePath: String!

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.

top
EmailAddress
emailAddress: String!
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
hashAlgorithm: String!
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
LastErrorHtml
lastErrorHtml: String! (read-only)

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
lastErrorText: String! (read-only)

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
lastErrorXml: String! (read-only)

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
lastMethodSuccess: Bool

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
Locality
locality: String!
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
mgfHashAlg: String!
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
pssPadding: Bool
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
state: String!
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
verboseLogging: Bool

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
version: String! (read-only)

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

Methods

AddSan
addSan(sanType: String, sanValue: String) -> Bool
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.

The sanType specifies the type of SAN, and can be one of the following strings:

  • otherName
  • rfc822Name
  • dnsName
  • x400Address
  • directoryName
  • ediPartyName
  • uniformResourceIndicator
  • IPAddress
  • registeredID

The sanValue is the value. For example, if the sanType is "dsnName", the sanValue might be "example.com". If the sanType is "IPAddress", then the sanValue might be "69.12.122.63".

Returns true for success, false for failure.

top
GenCsrBd
genCsrBd(privKey: CkoPrivateKey, csrData: CkoBinData) -> Bool

Returns true for success, false for failure.

top
GenCsrPem

Introduced in version 9.5.0.65

Generate a CSR and return it as a PEM string. The privKey can be an RSA or ECDSA private key.
