You need a passphrase to unlock the secret key for
user: "Tyrone Slothrop <tyrone.slothrop@yoyodyne.com>"
4096-bit RSA key, ID 0xABD9088171345468, created 2014-06-06
ASCII armored output forced.
Revocation certificate created.
Please move it to a medium which you can hide away; if
Mallory gets access to this certificate he can use it to
make your key unusable.
It is smart to print this certificate and store it away,
just in case your media become unreadable. But have some
caution: The print system of your machine might store the
data and make it available to others!
Do take the advice and move this file off the BeagleBone. Printing it out and storing it
somewhere safe is a good option, or burn it to a CD.
Note
The lifespan of a CD or DVD may not be as long as you think. The United States National
Archives Frequently Asked Questions (FAQ) page on optical storage media states that:
"CD/DVD experiential life expectancy is 2 to 5 years even though published life expectan-
cies are often cited as 10 years, 25 years, or longer."
Refer to their website

faq.html
for more details.
Lastly, create an encrypted backup of your encryption key and consider storing that in a
safe location on durable media.
