.SH NAME
|
|
borg-key-change-passphrase \- Change repository key file passphrase
|
|
.SH SYNOPSIS
|
|
.sp
|
|
borg [common options] key change\-passphrase [options] [REPOSITORY]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
The key files used for repository encryption are optionally passphrase
|
|
protected. This command can be used to change this passphrase.
|
|
.sp
|
|
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.
|
|
