Lua Requires Chilkat v11.0.0+

Verify SSL Server Certificate

See more Socket/SSL/TLS Examples

Demonstrates how to connect to an SSL server and verify its SSL certificate. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local socket = chilkat.Socket.new()

local ssl = true
local maxWaitMillisec = 20000

-- The SSL server hostname may be an IP address, a domain name,
-- or "localhost".
local sslServerHost = "www.paypal.com"
local sslServerPort = 443

-- Connect to the SSL server:
local success = socket:connect(sslServerHost, sslServerPort, ssl, maxWaitMillisec)
if not success then
    print(socket.last_error_text)
    return
end

local cert = chilkat.Cert.new()

local bExpired = false
local bRevoked = false
local bSignatureVerified = false
local bTrustedRoot = false

success = socket:get_server_cert(cert)
if success then
    print("Server Certificate:")
    print("Distinguished Name: " .. cert.subject_dn)
    print("Common Name: " .. cert.subject_cn)
    print("Issuer Distinguished Name: " .. cert.issuer_dn)
    print("Issuer Common Name: " .. cert.issuer_cn)

    bExpired = cert.expired
    bRevoked = cert.revoked
    bSignatureVerified = cert.signature_verified
    bTrustedRoot = cert.trusted_root

    print("Expired: " .. tostring(bExpired))
    print("Revoked: " .. tostring(bRevoked))
    print("Signature Verified: " .. tostring(bSignatureVerified))
    print("Trusted Root: " .. tostring(bTrustedRoot))
end

-- Close the connection with the server
-- Wait a max of 20 seconds (20000 millsec)
success = socket:close(20000)
