I hit reply to quick and only to you directly, sorry, so here my initial question and
your quick reply to it:

no that I recall, but IMO they're quite related (and FWIW, I wished for the file one already
in the past personally), so if it isn't too complicated I'd do them in one series.

above 9 lines could be

// check if any (non-empty) key fails to parse as SSH key
if (value.split('\n').every(key => key === '' || PVE.Parser.parseSSHKey(key))) {
    return "Failed to recognize ssh key";
}

you could also merge the checking for the multiline and single line case:

let keys = value.indexOf('\n') !== -1 ? value.split('\n') : [ value ];

if (keys.every(key => key === '' || PVE.Parser.parseSSHKey(key))) {
    // ..
