How to make encrypted journal with Mémoires
October 1, 2007 by Dmitry
Update: Mémoires has the built-in encryption as of version 1.1.
We are going to add native password-encrypted journals in one of the future releases (probably, 2.0) after we polish the current feature set, but you can have them already. Actually, you can encrypt any files (not only Mémoires journals) using the built-in feature of Mac OS X. Here’s how to do it:
Open Disk Utility (it’s located in Applications/Utilities).
Click New Image.
Enter the name of a disk, for example, Encrypted disk, select disk size (for example 40 MB, if that’s enough for your journal), select AES-128 (recommended) encryption, and click Create.

You’ll be asked to enter password. Do it. (Deselect Remember password for more security.)
Your encrypted disk image has been created and mounted! Now save your journal to it (in Mémoires click File > Save As…, select “Encrypted Disk” or whatever you called it.)

When you’re done, eject encrypted disk to make your journal private.
The next time you’ll need your journal, first mount your encrypted disk by double-clicking on it (for example, my disk is located in Documents, so I go to Documents in Finder and double-click “Encrypted disk” file.) When it’s mounted, you’ll be asked to enter your password. Enter it and double-click the Mémoires journal inside this disk.

I suggest using “sparse disk image” instead “read/write disk image” in step 3
Yes, that makes sense. Thanks for suggestion!
