Thanks for your reply, but i don't know how to debug storeio :-(
If i should continue this thread in help-hurd please to tell me it

i installed the debian package libc0.3-dbg (that installs the libc with
debug in /lib/debug) and compiled the hurd, then i've done three test:

 $ cp crypt.c hurd/libstore ; cd hurd/libstore

added -lcrypto in Makefile for OpenSSL

 $ make libstore_crypt.so.0.3
 $ export LD_LIBRARY_PATH=$PWD:/lib/debug
 $ cd ../storeio
 $ make
 $ settrans -Pac ~/test storeio -T crypt ~/pippo.enc
 crypt: Invalid argument to --store-type

well i try to run a typed store to have the time to pause:

 $ settrans -Pac ~/test storeio -T crypt ~/pippo.enc
 Translator pid: 1234

in another shell (in the same directory with the same LD_LIBRARY_PATH):

 $ gdb -d ../libstore storeio 1234
Attaching to program: storeio, process 1234
Reading symbols from /lib/libstore.so.0.3...done.
Loaded symbols for /lib/libstore.so.0.3
Reading symbols from /libc.so.0.3...done.
Loaded symbols for /libc.so.0.3

why my LD_LIBRARY_PATH environment variable is not used for dynamic
linking?  I think this only appears when using settrans

the second test was:

 $ cd hurd/libstore

created a test store class from file store class

 $ make libstore_test.so.0.3
 $ settrans -Pac ~/test ../storeio/storeio -T test ~/pippo.enc
 test: Invalid argument to --store-type

the third:

 $ cd hurd/storeio
 $ make storeio.static
 $ settrans -Pac ~/test storeio.static -T crypt ~/pippo.enc
 $ cat ~/test
 Invalid argument (or similar i don't remember)
 $ settrans -Pac ~/test storeio.static -T file ~/pippo.enc
 $ cat ~/test
 Invalid argument (or similar)

Should i compile a static storeio in another way?
It is normal that my LD_LIBRARY_PATH is not used when setting translators?
It is correct what i've done to debug?  If it is ok i'll try to reinstall
the system with an updated Debian GNU Hurd (i'm using J2).
