Description Takashi Iwai 2007-03-15 12:00:47 UTC

encfs can no longer mount the old encrypted directory after upgrading from 10.2.

% encfs ~/.memo/ ~/memo/
EncFS Password: xxxxxx
Error decoding volume key, password incorrect

It seems like the upgrade of openssl affects the behavior.  Downgrading openssl (and encfs.rpm to remove some dependency) resolves the problem.

The packages used are:
encfs-1.3.2-3
openssl-0.9.8e-2

Takashi, can you please post output of

  encfsctl info ~/.memo

?

Comment 2 Takashi Iwai 2007-03-21 10:37:46 UTC

It's not the case, I'm afraid...

% encfsctl info ~/.memo

Comment 3 Forgotten User sLJ7K2dvxj 2007-04-12 07:14:32 UTC

It's been confirmed to be a bug in openssl.

This commit should fix it:
   http://cvs.openssl.org/chngview?cn=15978

Compliments to Valient Gough for tracking it down.

Closing bug.
