Error open LUKS partition in Windows 7

[karunass]

I have flash drive with LUKS partition. I have created it by cryptsetup in Ubuntu with 4096 bytes key. Key stored in file. I use LibreCrypt version 6.2, downloaded from github and try to open my flash drive in Windows 7 (64 and 32 bit versions). In both versions i get error:
"Unable to open container. Please check your keyphrase and settings, and try again."
FreeOTFE version 5.21 opened this flash with the same key without any problems.
Maybe my key file need to be in some special format for LibreCrypt?

P.S. Sorry for my english.

Hi,
I can't reproduce it exactly in the latest build - LC opens a LUKS container created on Linux using a keyfile OK for me.
But I've recently fixed a bug that was giving this error if the key was not in the first keyslot, whether a keyfile or password.
Could you please post the output of crytpsetup luksDump for the volume, to check if it's this, thanks.

OK, so it looks like the keyfile was added to the 2nd slot - and it could well be this.
Please can you try again with this executable
thanks

No, with this version i get the same error.

[t-d-k]

OK, this is odd.
Could you please post the cryptsetup commands you used to add the keyfile to the LUKS volume.
If you created it with cryptsetup luksAddKey make sure you have "keyfile contains ASCII password" off, as in the attached screenshot.
Could you also try with the file 'LUKS.box', and the keyfile 'keyfile' which you can find here

[karunass]

i used the following commands
sudo cryptsetup luksFormat /dev/sdb1 -d ./keys/master.key
sudo cryptsetup luksAddKey /dev/sdb1 ./keys/sdcard.key -d ./keys/master.key
"keyfile contains ASCII password" was off. I tried to mount with master.key and sdcard.key, but get error.

[karunass]

I have tried with 'LUKS.box', and the keyfile 'keyfile' from here, but got this error again :(

[t-d-k]

It looks like it might be a more fundamental error then. Can you open the file LUKS.box without a keyfile - just using the password 'password'? If that doesn't work could you please try with 'a.box' and the password 'password'.
thanks

I get exactly the same problem even with the latest 6.3 executable on Windows 7 64bit :-( It can create the volumes but doesn't mount them with the "Unable to open container. Please check your keyphrase and settings, and try again." Tried with both files and partitions created either in Windows or Linux ....

[karunass]

I have tried to open LUKS.box and a.box with password 'password'. a.box was opened successfully, but with LUKS.box i got error "Unable to open container. Please check your keyphrase and settings, and try again."

Same issue here with LUKS on Windows 7. As a workaround, I removed a broken LibreCrypt package and replaced with FreeOTFE version 5.21 which works fine, until the issue is fixed.

For what it's worth, this issue affects me also. Windows 8 x64. Same scenario as above - second keyslot doesn't work whilst it does on Linux.

Got this problem too. I used keyfiles to secure my backups on external drive and now I can't open it.
