Support for osk-sdl

[root2185]

Can you make the script work also when using osk-sdl to unlock LUKS?
This is the script that I set in crypttab from the Mobian package:

#!/bin/sh

if [ -z "${CRYPTTAB_SOURCE}" ] || [ -z "${CRYPTTAB_NAME}" ]; then
    echo "This is a crypttab keyscript script, don't run directly." 1>&2
    exit 1
fi

export SDL_VIDEODRIVER=kmsdrm

plymouth hide-splash 2>/dev/null

exec /usr/bin/osk-sdl -k -d "${CRYPTTAB_SOURCE}" -n "${CRYPTTAB_NAME}" -c /etc/osk.conf

plymouth show-splash 2>/dev/null

Is possible to integrate it into the keyctl_keyscript one?

it seems possible to integrate it, but i'm not sure it's worth to include it directly.

to be honest i'm very sorry but i've currently no time to do the integration, but i'm always open to PRs.

you could add it as an additional backup method to ask for a pw.
eg. see https://github.com/gebi/keyctl_keyscript/blob/master/decrypt_keyctl#L44

To make it possible to integrate your PR:

• current setups should not be impacted
• zero config (thus added as backup method that's choosen when other methods don't work)
• added after the askpass method (and before "last resort" methods)
• be the same coding style

as the upstream project osk-sdl does not provide documentation in the repo on how to call it to get the values into the shell environment i can not help you with that, but i'm not sure how your example from above should work.

it would need a method like askpass is used, where the password is just returned, or directly written into the user keyslot would also work.

A new passphrase caching script for osk-sdl, can you do it if better documentation is provided?

Do you mean the passphrase?
The man page has some info:

-k, --keyscript
Enable keyscript mode. Password will be output to STDOUT for use with another program such as cryptsetup-initramfs.
