Encrypting and Decrypting Information

When you save a stream, node, project, output file, or model nugget, you can encrypt it to prevent its unauthorized use. To do this, you select an extra option when saving, and add a password to the item being saved. This encryption can be set for any of the items that you save and adds extra security to them; it is not the same as the SSL encryption used if you are passing files between IBM® SPSS® Modeler and IBM SPSS Modeler Server.

When you try to open an encrypted item, you are prompted to enter the password. After you enter the correct password, the item is decrypted automatically and opens as usual.

To Encrypt an Item

1. In the Save dialog box, for the item to be encrypted, click Options. The Encryption Options dialog box opens.
2. Select Encrypt this file.
3. Optionally, for further security, select Mask password. This displays anything you enter as a series of dots.
4. Enter the password. Warning: If you forget the password, the file or model cannot be opened.
5. If you selected Mask password, re-enter the password to confirm that you entered it correctly.
6. Click OK to return to the Save dialog box.

Note: If you save a copy of any encryption-protected item, the new item is automatically saved in an encrypted format using the original password unless you change the settings in the Encryption Options dialog box.
