Hello All,
I am working on developing an Engine in OpenSSL to access cipher
hardware we are developing. I am not having any "good" luck trying to
get the test code, in particular evp_test.c, to call into my engine code
for testing. I believe I need to use the config file for OpenSSL Here
is what I have been able to do so far:
I am able to access the engine using a command line encode request for
example:
./apps/openssl enc -aes-256-ecb ... -engine myEngine ...
With this command the bind_myEngine() sequence is called and
myEngine_ciphers() is called to pass back the proper
_init()/_code()/_clean() set for the requested NID.
But to test the engine code via the "make test", or "cd test; make
test_evp" there is not the ability to pass in a command line "-engine
myEngine" parameter.
I have, I think, properly setup the environment variable OPENSSL_CONF to
point to the openssl.cnf file in ./apps folder.
echo $OPENSSL_CONF
/home/johng/openSSL/openssl-0.9.8a/apps/openssl.cnf
I have added the following lines for my engine:
# Extra OBJECT IDENTIFIER info:
#oid_file = $ENV::HOME/.oid
oid_section = new_oids
engines = engine_section
(At the bottom of the openssl.cnf file:)
[engine_section]
myEngine = myEngine_section
[myEngine_section]
#see if I can get any failure/error message
snaf_ctrl = EMPTY
# Supply all default algorithms
default_algorithms = ALL
At this point, when I run the make test_evp command, the bind_myEngine()
sequence is called and myEngine_ciphers() is also called, with cipher
and nid == 0 to get the list of NIDs supported by the engine.
However when the ciphers are tested, using evptests.txt, my engine's
_init()/_code()/_clean() are not called and I get the following Debug
message from tb_cipher.c:
engine_table_dbg: tb_cipher.c:116, nid=426, caching 'no matching ENGINE'
Can anyone offer me some advice on what other "things" I need to do in
order to get the calls into myEngine? Or what other places I need to
look/try to figure out why tb_cipher reports "no matching ENGINE"
instead of passing back the matching ENGINE pointer?
Thank you very much for any help you can send my way.
