# Note: Requires Chilkat v9.5.0.83 or greater.

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

key = chilkat.CkSshKey()

    print(key.lastErrorText())
    sys.exit()

# We can optionally set a comment to be included in the exported key.
key.put_Comment("This is my new ed25519 key.")

# Export the ed25519 private key to unencrypted PuTTY format:
exportEncrypted = False
exportedKey = key.toPuttyPrivateKey(exportEncrypted)
success = key.SaveText(exportedKey,"qa_output/privkey_putty_unencrypted.ppk")

# The unencrypted PuTTY key looks like this:
