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

Chilkat2 PHP

<?php

use Chilkat2\SshKey;

$sshkey = new SshKey();

// 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.)
try {
    $sshkey->FromOpenSshPrivateKey($strKey);
    echo "Loaded OpenSSH private key.\n";
    exit;
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
}

// If the key is an OpenSSH public key:
try {
    $sshkey->FromOpenSshPublicKey($strKey);
    echo "Loaded OpenSSH public key.\n";
    exit;
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
}

// If the key is a PuTTY private key:
try {
    $sshkey->FromPuttyPrivateKey($strKey);
    echo "Loaded PuTTY private key.\n";
    exit;
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
}

// If the key is an RFC 4716 public key:
try {
    $sshkey->FromRfc4716PublicKey($strKey);
    echo "Loaded RFC 4716 public key.\n";
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
