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

$sftp = New-Object Chilkat.SFtp

# Set some timeouts, in milliseconds:
$sftp.ConnectTimeoutMs = 15000
$sftp.IdleTimeoutMs = 15000

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
$hostname = "sftp.example.com"
$port = 22
$success = $sftp.Connect($hostname,$port)
if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
}

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
$success = $sftp.AuthenticatePw("myLogin","myPassword")
if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
}

# After authenticating, the SFTP subsystem must be initialized:
$success = $sftp.InitializeSftp()
if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
}

# Download the file:

$localFilePath = "c:/temp/hamlet.xml"
# Note: The remote filepath may be an absolute filepath,
# a relative filepath, or simply a filename.  
# Relative filepaths are always relative to the home directory
# of the SFTP/SSH user account.  There is no such thing
# as "current remote directory" in the SFTP protocol. 
# A filename with no path implies that the file is located
# in the SFTP user account's home directory.
$remoteFilePath = "subdir1/subdir2/hamlet.xml"
$success = $sftp.DownloadFileByName($remoteFilePath,$localFilePath)
if ($success -ne $true) {
    $($sftp.LastErrorText)
    exit
