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

* 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

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:

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

loXml.LoadXml(lcSubjectAltNameXml)

i = 0
