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

cert = chilkat.CkCert()

success = cert.LoadFromFile("qa_data/certs/testIcpBrasil.cer")
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

subjectAltNameXml = 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:

xml = chilkat.CkXml()

xml.LoadXml(subjectAltNameXml)

i = 0
count_i = xml.NumChildrenHavingTag("name")
while i < count_i :
    xml.put_I(i)
    oid = xml.chilkatPath("name[i]|(oid)")
    name = xml.getChildContent("name[i]")
    i = i + 1

rfc822Name = xml.getChildContent("rfc822Name")
