Change keypairs file to encrypted format (DEWIF)

  • migrate to dup-crypto 0.11.1
  • remove all .seed access
  • Add option -f, --from-file to subcommands dunitrust keys modify network|member to add ability to import a DEWIF file.
  • Change keypairs file location to keypairs.dewif
  • At startup, if file keypairs.dewif not exist, don't create it alert user with a message like "no keypairs configuired, use temporary random network keypair". If file keypairs.dewif exist, Ask the user for the passphrase that will decrypt the file.
