Subject Alternative Name

See more Certificates Examples

Demonstrates the usage of the SubjectAlternativeName property to get the certificate SAN (subject alternative name) as XML. Lua

local chilkat = require("chilkat")

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

local cert = chilkat.Cert.new()

local success = cert:load_from_file("qa_data/certs/testIcpBrasil.cer")
if not success then
    print(cert.last_error_text)
    return
end

local subjectAltNameXml = cert.subject_alternative_name

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:

local xml = chilkat.Xml.new()

xml:load_xml(subjectAltNameXml)

local oid = ""
local name = ""

local i = 0
local count_i = xml:num_children_having_tag("name")
while i < count_i do
    xml.i = i
    oid = xml:chilkat_path("name[i]|(oid)")
    name = xml:get_child_content("name[i]")
    i = i + 1
end

local rfc822Name = xml:get_child_content("rfc822Name")
