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

loCert = createobject("CkCert")

llSuccess = loCert.LoadFromFile("qa_data/certs/testIcpBrasil.cer")
if (llSuccess = .F.) then
    ? loCert.LastErrorText
    release loCert
    return
endif

lcSubjectAltNameXml = loCert.SubjectAlternativeName

? lcSubjectAltNameXml

// 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:

loXml = createobject("CkXml")

loXml.LoadXml(lcSubjectAltNameXml)

i = 0
lnCount_i = loXml.NumChildrenHavingTag("name")
do while i < lnCount_i
    loXml.I = i
    lcOid = loXml.ChilkatPath("name[i]|(oid)")
    lcName = loXml.GetChildContent("name[i]")
    i = i + 1
enddo
lcRfc822Name = loXml.GetChildContent("rfc822Name")
