-----------------------------------------+---------------------------------
 As discussed in #16645: (Ed25519 key backups) printing it on paper, QR
 codes, email, cloud, portable storage media, backup servers, you name it
 should all be possible for an user.

 I suggest using Base58Check encoding (it removes 0OIl chars) - makes it
 easier to re-create the key from a paper printed version of it.

 An ascii-armored version for the key files should be used by default
 regardless if the master Ed25519 key is encrypted with a passphrase or
 not.
