NAME

       borg-key-change-passphrase - Change repository key file passphrase

SYNOPSIS

       borg [common options] key change-passphrase [options] [REPOSITORY]

DESCRIPTION

       The  key  files  used  for repository encryption are optionally passphrase protected. This
       command can be used to change this passphrase.

       Please note that this command only changes the passphrase, but not any secret protected by
       it  (like  e.g. encryption/MAC keys or chunker seed).  Thus, changing the passphrase after
       passphrase and borg key got compromised does not protect future (nor past) backups to  the
       same repository.

OPTIONS

       See borg-common(1) for common options of Borg commands.

   arguments
       REPOSITORY

          # Create a key file protected repository
          $ borg init --encryption=keyfile -v /path/to/repo

          Enter new passphrase:
          Enter same passphrase again:
          Remember your passphrase. Your data will be inaccessible without it.
          Key in "/root/.config/borg/keys/mnt_backup" created.
          Keep this key safe. Your data will be inaccessible without it.
          Synchronizing chunks cache...
          Archives: 0, w/ cached Idx: 0, w/ outdated Idx: 0, w/o cached Idx: 0.
          Done.

          # Change key file passphrase
          $ borg key change-passphrase -v /path/to/repo
          Enter passphrase for key /root/.config/borg/keys/mnt_backup:
          Enter new passphrase:
          Enter same passphrase again:
          Remember your passphrase. Your data will be inaccessible without it.
          Key updated

       Fully automated using environment variables:

          $ BORG_NEW_PASSPHRASE=old borg init -e=repokey repo
          # now "old" is the current passphrase.
          $ BORG_PASSPHRASE=old BORG_NEW_PASSPHRASE=new borg key change-passphrase repo
          # now "new" is the current passphrase.
