(Chilkat2-Python) SCP Download/Upload Binary Files as Encoded Strings

Demonstrates how to upload and download binary files as encoded strings (base64, hex, etc.) using the SCP protocol (Secure Copy Protocol over SSH).

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

ssh = chilkat2.Ssh()

# Hostname may be an IP address or hostname:
hostname = "www.some-ssh-server.com"
port = 22

# Connect to an SSH server:
success = ssh.Connect(hostname,port)
if (success != True):
    print(ssh.LastErrorText)
    sys.exit()

# Wait a max of 5 seconds when reading responses..
ssh.IdleTimeoutMs = 5000

# Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != True):
    print(ssh.LastErrorText)
    sys.exit()

# Once the SSH object is connected and authenticated, we use it
# in our SCP object.
scp = chilkat2.Scp()

success = scp.UseSsh(ssh)
if (success != True):
    print(scp.LastErrorText)

remotePath = "images/starfish.jpg"

# Download the binary file and return as a base64 string.
# See <a href="http://www.cknotes.com/chilkat-binary-encoding-list/">List of Encodings</a> for a list of possible encodings.
encodedJpg = scp.DownloadBinaryEncoded(remotePath,"base64")
if (scp.LastMethodSuccess != True):
    print(scp.LastErrorText)
    sys.exit()

remotePath = "images/starfish2.jpg"

# Now upload from the base64 string to the SSH server.
# Insided the call to UploadBinaryEncoded, the base64 string is decoded,
# and the decoded bytes are uploaded.  The resulting starfish2.jpg on the
# server will be identical to the original starfish.jpg
success = scp.UploadBinaryEncoded(remotePath,encodedJpg,"base64")
