Example 1
- Encrypted PGP message inside encrypted word file.
Example 2
- Encrypted PGP message inside plain text document (notepad, gedit...).
To me it makes some sense the first example, but I am curious if word files have any bugs or exploids that could expose the content of the encrypted message inside the document.
go with example 2. not because there is a difference in the security but it is better because you do not have to deal with formatting. regarding your security concerns: an attacker could exploit a vulnerability in gedit or word to gain access to your os and then read your messages. however just use tails and you will not have to worry about such things as a normal buyer.
also please post such questions on the noobs sub next time.
