Sending Secure Email Attachments

SafeHouse Explorer makes it easy to send secure email attachments using any email application, including Outlook and popular webmail tools. SafeHouse volumes are ordinary Windows files and can be attached to emails in the same way as you attach any other file.

Of course, you obviously would not want to include the password to an attached volume inside the same email, so you'll need to find some alternate method for letting the recipient know the password. You also need to consider that the recipient may not already have SafeHouse Explorer installed, and you might want to include a link to the free SafeHouse Explorer download page.

Follow these steps send a secure email attachment:
  1. Create a volume large enough to hold the files you wish to send, but not too large.

  2. Open the volume and add your confidential files.

  3. Close the volume and add attach it to your email.

  4. Include a link in your email to the free SafeHouse Explorer download page.

  5. Find some way to communicate the password to your recipient (such as by phone).

Compressed File Attachments

You'll generally find that SafeHouse volumes do not compress all that well. The reason for this is that encryption by nature yields results which are not easily compressed because character sequences found in ordinary text will no longer exist once encrypted.

One thing you can do to help a little in this area is to not pre-initialize new volumes with random data. Random data may be great for helping to foil intruders, but it's hard to compress. Don't worry, turning this feature off will not reduce the protection of your files. It's simply an additional tool which provides yet one more way to frustrate intruders on top of an already-secure encryption system.

Where disabling this feature might help is that unused portions of your volume will easily compress. If you create a volume which is 10MB and then only fill it with 2MB worth of files, the unused 8MB area will compress nicely; meaning that the final compressed size of the volume will be closer to 2MB rather than 10MB.
