Endpoint Encryption for Files and Folders client
| 79
The self-extractor is packaged into a *.cab file as these are widely recognized in most
computer environments and the likelihood to pass e-mail virus scanners increases.
Otherwise, the plain *.exe is most likely to be blocked. However, proactive e-mail
virus scanners may very well block also the *.cab file as they detect an *.exe hidden
in the cabinet file. Thus, it may happen that e-mails sent with *.cab self-extractor
attachments are blocked.
Before creating the self-extractor *.cab package and attaching it to a new e-mail, the
user is asked to provide a password to be used to encrypt the self-extractor.
By clicking OK, the self-extractor is packed into a *.cab file and then attached to a
new e-mail ready to be sent.
Opening a Self-Extractor
For any of the two creation scenarios described above, opening and viewing the self-
extractor is done in the same manner. For e-mail attachments, however, the self-
extractor file must first be unpacked from the *.cab file. The user then just double-
clicks the Self-Extractor file. The user will then be prompted for the password used to
create and encrypt the self-extracting file. Thus, the creator of this file must submit
the password to the recipient of the file in a secure manner.
By default, after typing the correct password the content of the Self-Extractor will
open up automatically in the associated application However, the content won’t be
automatically saved to disk. When the user closes the application that opened up
the unpacked Self-Extractor content, the unpacked content will be wiped from the
disk. If the user instead wants to save the Self-Extractor content to disk, the
Advanced >> button must be selected.
This opens up an extra dialog where the user may select what to do with the unpacked
and decrypted Self-Extractor.
