This is a logical fallacy. It is called circular reasoning. I need a key to decrypt a key. I still have to store that secondary key somewhere, or the system will have to regenerate it. Regenerate means I can see it in the source. Storage means it is a sitting duck, unencrypted.
If you agree it's a fallacy, then what were you suggesting with:
Quote:
...the half-keys should be encrypted - both on the user side and the system side.
Unless your point was simply that you shouldn't keep them around indefinitely in retrievable form -- and I don't. I don't encrypt them though, just delete them at regular intervals, as the session times out.

maria-cso

MARIA-CSO(1)						      General Commands Manual						      MARIA-CSO(1)

NAME

       maria-cso - shared library generator for maria

SYNOPSIS

       maria-cso directory library.so file.c...
       maria-cso directory library.so file.c

DESCRIPTION

       This manual page documents briefly the maria-cso command.

       maria-cso  is  a  shell	script	invoked  by maria in order to compile generated C code into dynamically loadable shared object files.  The
       script invokes the C compiler and the linker, and it calculates checksums in order to avoid compiling unmodified modules.
       The directory argument specifies the location of the source files.  When the script is invoked with one file.c argument, it translates  the
       file to the shared object library.so.
       When maria-cso is invoked with multiple file.c arguments, it computes a checksum of a file named multiset.h and of each argument.  When the
       header file multiset.h has been changed since the previous invocation of maria-cso, everything will be recompiled.   Otherwise  only  those
       file.c modules that have been modified will be recompiled.  The checksum files are multiset.sum and c.sum.

SEE ALSO

       maria(1), sh(1).

ENVIRONMENT VARIABLES

       CC     Name of the C compiler

       CFLAGS Command-line switches to be passed to the C compiler

       DEFINES
	      Preprocessor macro definitions to be passed to the C compiler

FILES

       /usr/share/maria/runtime/*.h
	      Header files for the run-time library

AUTHOR

       This  manual  page  was	written  by Marko Makela <msmakela@tcs.hut.fi>.  The maria-cso script and the compilation option were designed and
       implemented by Marko Makela.  Please see the copyright file in /usr/share/doc/maria for details.
