[pbs-devel] [PATCH proxmox-backup] fix #3854 paperkey import to proxmox-tape

Tue Feb 8 12:51:19 CET 2022
added a parameter to the cli for reading a old paperkeyfile to restore
the key from it. For that i added a json parameter for the api and made
hint optional because hint is already in the proxmox-backupkey-json.
functionality:
proxmox-tape key paperkey [fingerprint of existing key] > paperkey.backup
proxmox-tape key create --paperkeyfile paperkey.backup
for importing the key it is irrelevant, if the paperkey got exported as html
or txt.
