password -md5 in grub.conf/menu.lst
In grub/menu.lst file my /boot partition is a line like this:
password --md5 $1$Mb9vxXPV$pAbcdTxr4Twh32XXgns2/
The last bit is 35 characters long.
Is this the hash digest of the passphrase? Is the final slash character (/) just another character or is it in some way especially significant?
tnx
This seems to be a config file option of grub-md5-crypt, and has nothing to do with cryptsetup, dm-crypt or LUKS.
If I understand the documentation correctly, this is an md5-ed password that either secures interactive Grub mode or prevents script continuation before password entry.
The format seems to be the same as in /etc/shadow
for md5 passwords. You can read up on it here:

P.S.: The "/" is an artefact of the encoding, no special
meaning. It can be one of 4 characters. The hash gets patted by "1111" (binary) at the end.
