Encrypting a Python toolbox

By default, a Python toolbox (.pyt) is a plain text file that can be edited in any text editor or Python IDE. However, in some cases, it may be desirable to hide the contents of the Python toolbox.

To encrypt a Python toolbox, right-click the toolbox and click Encrypt. When entering and confirming a password, a backup copy of the original .pyt file can be retained.

Caution:

The encryption of a Python toolbox is performed in place and will overwrite the original unencrypted file. It is recommended to back up the input file to avoid the loss of its contents in case the password is forgotten.

To decrypt an encrypted Python toolbox, right-click the toolbox and click Decrypt.

Additionally, ArcPy functions EncryptPYT and DecryptPYT can also be used to encrypt or decrypt Python toolboxes.
