Go Requires Chilkat v10.1.2+

Using WS_FTP Self-signed Certificate file (.crt) and Private Key File. (.key)

See more FTP Examples

Demonstrates how to use a self-signed certificate created by WS_FTP with Chilkat FTP2.

Note: It is usually not necessary for the FTP client to use a client-side certificate. Most FTP servers using SSL and TLS connections (explicit or implicit) do not require client-side certs. In addition, some high-security FTP servers require "real" certificates -- meaning certificates issued by a real certificate authority with a chain of authentication that leads to a trusted root certificate. The certificates created by WS_FTP are self-signed and untrusted.

    success := false

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

    //  Important:  Before running this program, convert your
    //  .crt and .key files to a .p12 using OpenSSL:
    //  The command is this:
    //  openssl pkcs12 -export -in test.crt -inkey test.key -out test.p12
    //  

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.example.com")
    ftp.SetPort(21)
    ftp.SetUsername("testLogin")
    ftp.SetPassword("testPassword")

    //  This example will use explict TLS/SSL.
    //  Establish an explicit secure channel after connection
    //  on the standard FTP port 21.
    ftp.SetAuthTls(true)

    //  The Ssl property is for establishing an implicit SSL connection
    //  on port 990.  Because this example uses explicit SSL, it 
    //  should remain false.
    ftp.SetSsl(false)

    //  Create an instance of a certificate store object, load a .p12 file,
    //  locate the certificate we need, and use it for signing.
    //  (a P12/PFX file may contain more than one certificate.)
    certStore := chilkat.NewCertStore()
    //  The 1st argument is the filename, the 2nd arg is the 
    //  .p12 file's password.  (OpenSSL will prompty you to set a password
    //  when converting the .crt and .key into a .p12).
    success = certStore.LoadPfxFile("test.p12","secret")
    if success != true {
