Post File Encryption Dialog

In this Topic ShowHide

Introduction

When using the Post File Encryption dialog on a post processor that has not been prepped in advance, the entire post will be encrypted and unreadable when opened. This can be used for a variety of reasons but the end result is that only the Licenses, or Customer ID's that were listed when encrypting will be able to use the post processor, unless the Work for Any License ID check box was selected. With a little bit of prep work, particular portions of the post can be encrypted, while the rest is left alone. To accomplish this, one must open the post processor and use <--BEGIN ENCRYPT and <--END ENCRYPT on their own line to box in the portion of the post to be encrypted. This topic explains the Post File Encryption dialog box parameters.

Original .BCPst file

Select - C:\BobCAD-CAM Data\*(CurrentVersion)*\Posts\Mill\BC_3x_Mill.BCPst

Clicking Select will open the File Open dialog to allow you to select the *.BCPst file to encrypt.  No changes will be made to the original file. The address above is used as an example.

Encrypted .BCPst file

Select - C:\BobCAD-CAM Data\*(CurrentVersion)*\Posts\Mill\BC_3x_Mill-Encrypted.BCPst

Clicking Select will open the Save As dialog to allow you to select the *.BCPst file to name the file after.  By default the Encrypted *.BCPst file will be named the same as the Original post file with “-Encrypted” added to the end of the file name, but the file can be named anything. The file should not use the same name as the original file, as that would overwrite the original copy.

Work for Any License ID

 - With this check box cleared, one of the other options must be used for encryption. Either a Supported License ID or a Supported Customer ID must be entered into the respective area.

 - With this check box selected, the post will work with any license ID.

Supported License ID

Enter all License ID's that should be allowed to work with the encrypted post. Multiple License ID’s can be entered in this list box which will make it so the post processor only works for those particular Licenses.

 Multiple licenses can be used when separated by commas:

• 1111, 2222, 3333

Commas with additional lines can be used as well:

• 1111,
  2222,
  3333

Supported Customer ID

Enter all Customer ID's that should be allowed to work with the encrypted post. Multiple Customer ID’s can be entered in this list box which will make it so the post processor only works for those particular ID's. This can be extremely helpful since, while the same customer will have a new License ID when they get a newer version of the software, they will usually maintain the same Customer ID. In this way, the same encrypted post would be able to be used in a newer version of the software.

 Multiple Customer ID's can be used when separated by commas:

• 1111, 2222, 3333

Commas with additional lines can be used as well:

• 1111,
  2222,
  3333

How to Encrypt an Entire Post

Once the Edit Toolpath dialog has launched, there are only a few key steps to follow:
