After upgrading to bookworm, encfs segfaults for me when trying to open encrypted directories created a long time ago.
The solution in https://askubuntu.com/questions/1405656/encfs-segfault-in-version-22-04 worked, which is to edit /etc/ssl/opensslf.conf and add [openssl_init] providers = provider_sect # List of providers to load [provider_sect] default = default_sect legacy = legacy_sect [default_sect] activate = 1 [legacy_sect] activate = 1 It would be great to document this in NEWS.Debian as this worked fine in bullseye enfsctl info says: Version 5 configuration; created by EncFS 1.2.5 (revision 20040813) Filesystem cipher: "ssl/blowfish", version 2:1:1 (using 3:0:2)
