Apple Keychain - Get Certificate by Common Name

See more Apple Keychain Examples

Retrieves the certificate from the Apple Keychain that matches the specified common name (CN). Lua

local chilkat = require("chilkat")

-- On MacOS or iOS, this searches both the Default keychains and System keychains for the certificate
-- having the specified CN.
local cert = chilkat.Cert.new()
local success = cert:load_by_common_name("Certum CA")
if not success then
    print(cert.last_error_text)
    return
end

print(cert.subject_dn)

-- Note: In the Apple Keychain, a certificate with its private key represents an identity because it combines the certificate and its private key.
-- When Chilkat loads a certificate from the Apple Keychain, it also gets the associated private key.
-- You can simply use the cert in other places in Chilkat where a cert w/ private key is required.
local cert2 = chilkat.Cert.new()
success = cert2:load_by_common_name("Chilkat Software, Inc.")
if not success then
    print(cert2.last_error_text)
    return
end

print(cert2.subject_dn)
local hasPrivKey = cert2:has_private_key()
print("Has private key: " .. tostring(hasPrivKey))

print("Success.")
