About password
In Tombo, password are keeps only memoy. There are no information keeps in file, registry.
And password in memory are removed when:
- Choose "erase password".
- You have no operations to TOMBO.
The time to forget can set by options.
If you forget your password, there are no way to decrypt except remember
or dictionary attack.
NOTICE!
As you know, there are no perfect security. But I think TOMBO provides some extent security enough for a general life.
Needless to say, to avoid decoding by cracker, you MUST choose password carefully - long enough, complex enough, hard to guess.
About encryption
If you think it is not enough to secure, you should choose other security products.
- TOMBO uses 128 bit BLOWFISH shared cypher.
I don't choose original cypher because it may not be secure.
- Code from GnuPG.
For reliability.
- Password are keep only memory.
When removing, memory has set to zero.
- There are no guard to access physical memory directly.
When release memory to OS, TOMBO clear memory to zero, but the memory allocated by OS are not cleared.
If someone wrote a program that search on physical memory,
maybe he/she can read notes (or its wreckage).
In TOMBO 1.9, message data(Menu, Dialog, etc) is separated file named "TomboMsg.txt".
To edit it, you will customize Tombo's messages.
In current version, there are only resources Japanese and English.
I hope someone is create other language version. Please send me your message file and I will add to distributions.
There are a few point to customize:
- File encoding is UTF-8.
- The message ID is depend on line no of the file. You should add/delete any more lines.
You will kick external application from context menu(right click menu on Windows, tap & hold on PocketPC, Alt+Click on H/PC).
It may be useful, but please use carefully.
If kicked application creates backup files, TOMBO does nothing to the file.
This means there are plain text(anyone can see) file even though you encrypt the notes by TOMBO.
Please check and decide yourself whether you use this feature.
You can disable to show save dialog when edit and leave the note.
To Supress save dialog, check "Options -> Memo View -> Disable save dialog".
You can discard changes to press Shift+ESC on edit view.
