``How long do you want these messages to remain secret?'' Randy asked, in his last message before leaving San Francisco. ``Five years? Ten years? Twenty-five years?''
After he got to the hotel this afternoon, Randy decrypted and read Avi's answer. It is still hanging in front of his eyes, like the afterimage of a strobe:
I want them to remain secret for as long as men are capable of evil.
Something people don't seem to be considering. Even if an encrypted communication is secure given today's technology and/or willingness to expend effort and resources, it becomes more readily accessible over time and decryption capabilities increase.
If and as communications are being recorded wholesale, how long until that encrypted communication is within ready reach of an unintended recipient?
In considering your security, you need to think not only of the present but also of the future.
Wow.
