- At this stage I can offer nothing more than my word. I am a
- senior government employee in the intelligence community. I
- hope you understand that contacting you is extremely high risk
- and you are willing to agree to the following precautions before
- I share more. This will not be a waste of your time.
- The following sounds complex, but should only take minutes
- to complete for someone technical. I would like to confir
- out of email that the keys we exchanged were not intercepted
- and replaced by your surveillants. Please confirm that no one
- has ever had a copy of your private key and that it uses a strong
- passphrase. Assume your adversary is capable of one trillion
- guesses per second. If the device you store the private key and
- enter your passphrase on has been hacked, it is trivial to decrypt
- our communications.
- Understand that the above steps are not bullet proof, and
- are intended only to give us breathing room. In the end if you
- publish the source material, I will likely be immediately impli
- This must not deter you from releasing the information
- I will provide.
- Thank you, and be careful.
