Subject: [PATCH] cryptsetup: Add LUKS2 token support.
|
|
|
4bff0a |
|
|
|
4bff0a |
LUKS2 supports so-called tokens. The libcryptsetup internally
|
|
|
4bff0a |
support keyring token (it tries to open device using specified
|
|
|
4bff0a |
keyring entry).
|
|
|
4bff0a |
Only if all token fails (or are not available), it uses a passphrase.
|
|
|
4bff0a |
|
|
|
4bff0a |
This patch aligns the functionality with the cryptsetup utility
|
|
|
4bff0a |
(cryptsetup luksOpen tries tokens first) but does not replace
|
|
|
4bff0a |
the systemd native ask-password function (can be used the same in
|
|
|
4bff0a |
combination with this patch).
|
|
|
4bff0a |
|
|
|
4bff0a |
(cherry picked from commit 894bb3ca4c730cc9e9d46ef5004ba4ca5e201d8d)
|
|
|

Resolves: #1719153
