1. Has the encryption algorithm been upgraded in MyInfo 4? There was some discussion on this subject back in early 2006, but I'm not sure what, if any, has been done in this area.

2. If I maintain an encrypted partition on a USB drive, say by using TrueCrypt, are there any issues in running MyInfoPortable in the encrypted partition?

3. If anyone out there is using third-party encryption software to encrypt all or some MyInfo topic files, can you share your experience and recommend an encryption software that can be used with MyInfoPortable on a USB drive?

Regards,

Jamal,

The encryption in MyInfo 4 is still the standard ZIP encryption used in the previous versions. However, we are going to include the industrial standard - 256 AES encryption in the next few months in MyInfo Pro.

As for TrueCrypt and MyInfo Portable - I haven't tested it, but there should be no problems.

Petko,

It's good to know that industry standard strong encryption is coming soon to MyInfo. I'm sure many users will be looking forward to that

I did some testing with TrueCrypt. Saving/retrieving specific topics in a file-hosted TrueCrypt volume seems to work fine. On Windows, file-hosted volumes appear to be more appropriate for USB sticks than partition-hosted volumes, unless one wants to encrypt the entire stick as one partition. TrueCrypt supports running a program from a volume, so it's possible to install and run MyInfo from an encrypted volume, but I haven't tested it.

I need to test indexing with encrypted topics. Question: Is the index for all topics stored in a single file? Or is it stored per topic? In a scenario in which topics are saved on different drives, is the entire index saved in the installation directory?

MyInfo creates index file for each topic, so they are multiple index files. They are not stored on the USB stick, but in the Application Data folder on the host computer. When you close MyInfo, they are deleted (I am talking here for the temporary index files used by MyInfo for the open topics; when you close and save a topic, the index is saved in the topic file along all other topic data).

That's good. From an encryption point of view, that makes it easy to secure the topic completely. As the index is stored within the topic file, encrypting a topic secures the content + the index in one sweep and in one place which is also selectable by the user.
