well, if openssl is build without DES support the DES nids are not
added to the internal list of OIDs when OPENSSL_add_all_ciphers is
called, hence the OBJ_* functions know nothing about DES.
logical
any chance to make openssl aware of -des-ecb when build without DES cipher
support using a dynamic Engine module?
what about adding the necessary ciphers in the engine initialization
function (have a look at crypto/evp/c_allc.c to see which functions
are necessary) ?
but loading seems to be ok
openssl enc -engine des-ecb
engine "des-ecb" set.
i tried a OSSL build with DES cipher support and got this
openssl enc -engine des-ecb -e -des-ecb -out testo -in testi
parallel processing
engine "des-ecb" set.
enter des-ecb encryption password:
Verifying - enter des-ecb encryption password:

is the EVP_CIPH_CTRL_INIT flag set in the EVP_CIPHER structure ?
it is (if you like, code is attached)
if the flag is set you must provide a support for this flag in
EVP_CIPHER::ctrl otherwise you get the above error (so if you don't
need that functionality don't use it).
Cheers,
