Topic: Saving private key in MS Word - page 2. (Read 1570 times)
To prevent the document corrupted file, use a paper wallet. When you come to use your paper wallet, empty it all into your live wallet then put the stuff you want kept safe into a new paper wallet.
I do not trust word not because of their encryption strength, but the integrity of the saved document. I have experienced word freezing while saving a document and corrupted the file. It was a large file with diagrams and photos, but still inexcusable. Save the keys in a plain text file and compress with 7zip or rar with 256bit aes encryption has the same effect.
This isn't the worst idea I've seen. I'm curious about what security experts think about this.
Certainly seems convenient, doesn't it?

I haven't actually done this, but how secure would this be? I know that Office 2003 and lower is very unsafe, only uses 40-bit encryption. But what about Office 2007-2010 which uses 128-bit encryption? Although according to Wikipedia:
I'm currently using Office 2013, does anyone know if Microsoft switched to 256-bit encryption in 2013?

The 128-bit key AES protection employed in Office 2007–2010 can still be considered as a relatively secure one. At the moment, however, cloud computing facilities are capable of unlocking a substantial number of the files saved in the Office 2007–2010 format.

Excel and Word 2010 still employ AES and a 128-bit key, but the number of SHA-1 conversions has doubled to 100,000 further reducing password recovery speed.
