used to run the application. Though this step is optional for adding a Code-
Cover feature, and by default all files, other than .exe, .dll, and .bpl, you
selected under the Files tab, will be encrypted.
To specify the file encryption settings:
1. Click the Change the file encryption options link in the Add
CodeCover Feature dialog box. The CodeCover file encryption
settings dialog box appears.

2. Select the Encrypt/decrypt the following files at run-time check
box. Now, type the file extensions in the edit field. This field can contain
up to 255 characters. You can filter files using the wildcard symbols
asterisk (*) and semicolon (;). The 8.10 naming convention is
followed, meaning that the file name and extension cannot exceed 8
and 10 characters, respectively. File filters like, *.*, *name.* are not
acceptable. Given below is a description of the valid conventions:
Providing Files for Encryption/Decryption
Convention Example
*.extension *.txt will encrypt/decrypt files. For example,
settings.txt and install.txt.
name*.* safe*.* will encrypt/decrypt files. For example,
safeobj.htm and safenet.cpp.
name*.extension safe*.txt will encrypt/decrypt files. For example,
safeobj.txt and safenet.txt.
3. The Toolkit automatically generates an encryption seed. If you want
to provide your own encryption seed, select the Specify my own
encryption seed check box and edit the value. Please note that if the
encrypted data files are shared by multiple applications, all the applications
must use the same encryption seed. The seed can consist of
two strings of 14 hexadecimal characters each (forming a 112-bit
long seed).
4. Click OK. You are returned to the Add CodeCover Feature dialog
box.
