Lua Requires Chilkat v11.0.0+

SFTP use Cert's Private Key from PFX (.pfx/.p12)

See more SFTP Examples

Demonstrates how to use the private key associated with a certificate from a .pfx/.p12 file. Lua

local chilkat = require("chilkat")

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

local cert = chilkat.Cert.new()

local pfxFilepath = "qa_data/pfx/my.pfx"
local pfxPassword = "secret"

-- A PFX typically contains certificates in the chain of authentication.
-- The Chilkat cert object will choose the certificate w/
-- private key farthest from the root authority cert.
-- To access all the certificates in a PFX, use the
-- Chilkat certificate store object instead.
local success = cert:load_pfx_file(pfxFilepath, pfxPassword)
if not success then
    print(cert.last_error_text)
    return
end

-- Get the private key.
local privKey = chilkat.PrivateKey.new()
success = cert:get_private_key(privKey)
if not success then
    print(cert.last_error_text)
    return
end

local privKeyPem = privKey:get_pkcs8_pem()
if not privKey.last_method_success then
    print(privKey.last_error_text)
    return
end

local sshKey = chilkat.SshKey.new()
success = sshKey:from_open_ssh_private_key(privKeyPem)
if not success then
    print(sshKey.last_error_text)
    return
end

-- Connect to an SSH/SFTP server
local sftp = chilkat.SFtp.new()
success = sftp:connect("sftp.example.com", 22)
if not success then
    print(sftp.last_error_text)
    return
end

-- Authenticate with the SSH server using a username + private key.
-- (The private key serves as the password.  The username identifies
-- the SSH user account on the server.)
success = sftp:authenticate_pk("mySshLogin", sshKey)
if not success then
    print(sftp.last_error_text)
    return
end

print("OK, the connection and authentication with the SSH server is completed.")

-- This example is only to show the connection + authentication using a private key associated with a certificate in the Windows certificate store...
