mnemonic phrase based backup for OpenPGP / GnuPG / gpg keys
Closed, DuplicatePublic

Description

In bitcoin (and other crypto currencies) usually a mnemonic phrase (also commonly called seed) [*] (commonly 12-24 human memorable words) are created as a backup which can deterministically create all wallet sub public and private keys. So one only has to remember these words and would always be able to restore its keys.

(These seed even allow creation of keys for different crypto currencies. In future, perhaps even for OpenPGP keys.)

  • That makes a file based backup optional if the phrase is memorized.
  • Allows easy paper backups with a pen.

That is the same as a key generated from a passphrase. We have already have a task T169 for this. Thus I merge them.
