[Bug 208801] Re: encrypted volumes aren't decrypted if the password is a space

[Jan Klötzke]

I think it could be caused by HAL, even though I didn't tested it. At
the end of the decryption chain the password is piped through stdin to
"/usr/lib/hal/scripts/linux/hal-luks-setup-linux" which then calls
cryptsetup. The script reads the password by executing "read PASSWORD".

Apparently bash strips any leading or trailing spaces in this case, which would explain the observed behaviour. See also

A short test script verified this. Replacing the line by "IFS= read
PASSWORD" should fix the problem. But as already said, I didn't tested
it in conjunction with KDE/HAL/cryptsetup...
