* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Cert')
loCert = CreateObject('Chilkat.Cert')

lnSuccess = loCert.LoadFromFile("qa_data/certs/testIcpBrasil.cer")
IF (lnSuccess = 0) THEN
    ? loCert.LastErrorText
    RELEASE loCert
    CANCEL
ENDIF

* If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
* then the Rfc822Name property returns XML.
lcSubjectAltNameXml = loCert.Rfc822Name

? lcSubjectAltNameXml

* Here's a sample of the subjectAltNameXml:

* <SubjectAltName>
*     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
*     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</name>
*     <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
*     <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
* </SubjectAltName>

* The XML can be parsed like this:

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXml = CreateObject('Chilkat.Xml')
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]")
    ? lcOid + ": " + lcName
    i = i + 1
