Hi,

I've been told to install OpenBSD alongside Windows and Debian (with
grub2) because it's my $dayjob laptop and I could have the need for
them. It's an x260 with UEFI. I have to give back the laptop now. In
case someone wanted to access the stuff I had on it, I changed the
softraid crypto password (let's just say it was so people don't see
that I'm using "hunter2" everywhere).

I updated the password with bioctl -P sd1 which worked correctly. Then
I rebooted and it says:

probing: pc0 mem[352K 204K 3273M 153M 4648M]
disk: hd0 sr0
>> OpenBSD/amd64 BOOTX64 3.32
Passphrase: <correct passphrase>
bcrypt_pbkdf failed
open(sr0a:/etc/boot.conf): Operation not permitted
boot>
Passphrase: <incorrect passphrase to test>
incorrect passphrase or keydisk
booting sr0a:/bsd: Passphrase: <correct passphrase to double check>
bcrypt_pbkdf failed
open(sr0a:/etc/boot.conf): Operation not permitted
failed(1). will try /bsd
boot>

I'm pretty sure it's the correct passphrase because I type a known
wrong passphrase the error message is not the same. The laptop was
installed in December 2016, I guessed the problem could have been the
switch:

> Switch softraid crypto from PKCS5 PBKDF2 to bcrypt PBKDF

if the boot loader hadn't been upgraded (because of grub2) but this
commit was on September 2016 so I guess it's something else.

Any idea what could it be?
Any idea what could have been done otherwise from the user side to
prevent this?
I'm asking mainly for other people, running the same fragile system. I
have backups so I should be fine (famous last words).

Cheers,
Daniel
