Subject Alternative Name

See more Certificates Examples

Demonstrates the usage of the SubjectAlternativeName property to get the certificate SAN (subject alternative name) as XML. Swift

func chilkatTest() {
    var success: Bool = false

    // Note: Not all certificates contain a Subject Alternative Name.
    // If it does not, the SubjectAlternativeName property will contain the empty string.

    let cert = CkoCert()!

    success = cert.load(fromFile: "qa_data/certs/testIcpBrasil.cer")
    if success == false {
        print("\(cert.lastErrorText!)")
        return
    }

    var subjectAltNameXml: String? = cert.subjectAlternativeName

    print("\(subjectAltNameXml!)")

    // Here's a sample of the subjectAltNameXml:

    // <?xml version="1.0" encoding="utf-8"?>
    // <SubjectAltName>
    //     <name type="oid" oid="2.16.76.1.3.4">...</name>
    //     <name type="oid" oid="2.16.76.1.3.2">...</name>
    //     <name type="oid" oid="2.16.76.1.3.3">...</name>
    //     <name type="oid" oid="2.16.76.1.3.7">...</name>
    //     <rfc822Name>...</rfc822Name>
    // </SubjectAltName>

    // The XML can be parsed like this:

    let xml = CkoXml()!

    xml.load(xmlData: subjectAltNameXml)

    var oid: String?
    var name: String?

    var i: Int = 0
    var count_i: Int = xml.numChildrenHavingTag(tag: "name").intValue
    while i < count_i {
        xml.i = i
        oid = xml.chilkatPath(cmd: "name[i]|(oid)")
        name = xml.getChildContent(tagPath: "name[i]")
        i = i + 1
    }

    var rfc822Name: String? = xml.getChildContent(tagPath: "rfc822Name")
