(Go) Load an SSH Key from a File (Many Formats Supported)

Demonstrates how to load an SSH public or private key object from a file. The file can be in any of the following formats:

• OpenSSH private key
• OpenSSH public key
• PuTTY private key
• RFC 4716 public key

    sshkey := chilkat.NewSshKey()

    // First, use the LoadText convenience method to load a text file (of any SSH key format)
    // into a string:
    strKey := sshkey.LoadText("../mySshKeys/myKey.txt")

    // Next, load the key into the SSH key object.

    // If the key is an OpenSSH private key:
    // (In actuality, the From* methods will automatically detect the format and load
    // the key correctly.  For example, if a PuTTY private key is passed to FromOpenSshPrivateKey,
    // it  will still load correctly.)
    success := sshkey.FromOpenSshPrivateKey(*strKey)
    if success != true {
        fmt.Println(sshkey.LastErrorText())
    }
    else {
        fmt.Println("Loaded OpenSSH private key.")
        sshkey.DisposeSshKey()
        return
    }

    // If the key is an OpenSSH public key:
    success = sshkey.FromOpenSshPublicKey(*strKey)
    if success != true {
        fmt.Println(sshkey.LastErrorText())
    }
    else {
        fmt.Println("Loaded OpenSSH public key.")
        sshkey.DisposeSshKey()
        return
    }

    // If the key is a PuTTY private key:
    success = sshkey.FromPuttyPrivateKey(*strKey)
    if success != true {
        fmt.Println(sshkey.LastErrorText())
    }
    else {
        fmt.Println("Loaded PuTTY private key.")
        sshkey.DisposeSshKey()
        return
    }

    // If the key is an RFC 4716 public key:
    success = sshkey.FromRfc4716PublicKey(*strKey)
    if success != true {
