You can always set your computer's clock to a different date if you like
a specific creation date of course.

Correct, but I like to certify my key from Governikus, which then
should have the same signing date. :-)

Since this day is so special (for me) I decided to do it again with a new (RSA)
key. But this time with a 'proper' Fingerprint, to celebrate this day. :-)

Maybe try generating new keys until you have a keypair of palindromic
primes,
or at least a palindromic fingerprint

A complete palindromic fingerprint would be absolutely awesome!!! But I
*strongly* doubt that this possible, in a timely manner, with my little GPU.

I know the palindrome day was yesterday (although the article missed
several others in the 21st century). I am curious on how you were able
to create a key with a certain fingerprint.

I used the (Windows) program scallion, from GitHub, with the following
parameters: scallion --gpg -k 2048 02022020

That's all and it took less than five seconds to generate the private key. :-)

That way you can also create keys with your birthday or deadbeef etc.

After key generation you have to import the private key into GnuPG
with '--allow-non-selfsigned-uid' to add a proper UID and passphrase.

Regards
Stefan

So, could you pipe in a script to create a fingerprint with the
following form:

n1 n2 n3 n4 n5 n6 n7 n8 n9 n10 n11 n12 n13 n14 n15 n16 n17 n18 n19 n20

n20 n19 n18 n17 n16 n15 n14 n13 n12 n11 n10 n9 m8 n7 n6 n5 n4 n3 n2 n1

where each n is a character of (1, 2, 3, 4, 5, 6, 7, 8, 9, 0, A, B, C,
D, E, F),
and where each n is allowed to be repeated, as long as it is the same
in its' corresponding mirror position,

i.e., n1 can = n3 as long as it is present in the first, and third
and thirty-eighth and fortieth position of the fingerprint).

It might not be that simple, but it doesn't seem impossible, to create
a Palindromic fingerprint,
(and just reset your computer clock to 02/20/2020 at 02:20 am) 8^))

The proplem is not piping etc., because I can input also a complete
Fingerprint. The problem is the computation time, like the same as
factoring a large modulus n.

As an example I just did as input only the short string 'deadbeefdeadbeef'
and it would take on my little GPU (see Predicted):

scallion --gpg -k 2048 deadbeefdeadbeef
