Demonstrates how to access the multiple names contained in the Subject Alternative Name of a certificate. This example is for an ICP Brasil certificate. Lianja

llSuccess = .F.

loCert = createobject("CkCert")

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

// 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:

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]")
    ? lcOid + ": " + lcName
    i = i + 1
