For a modern ed25519 key with cv25519 subkey paperkey outputs less than 10 
lines of data and a final CRC-24 checksum.

  1: 00 04 69 C7 01 A4 36 FD D4 96 FA E5 58 0A A1 51 BC 58 17 C2 28 CF 6A0F72
[...]
 10: B2 47 15 98 62 69 A9 53 BC B2 16 8F 9B 78 B4 BAF5C6
 11: BBEA88

In the old days computer magazines contained many pages of such hexdumps that 
you could hack into your computer to get some nice little games.
