Re: [openssl-users] RSA engine is not using the functions mentioned in struct

[khurram ashraf]

Respected Mr. Levitte,

I have created the symlink to 
/usr/lib/x86_64-linux-gnu/openssl-1.0.0/engines/librsa_engine.so. During 
encryption and decryption it mentions that "engine "rsa-engine 1" set", but it 
doesnot use the function in the struct and also doesnot output the printf. 
Furthermore, I also tried the method you recomended but still no result.


Best Regards.

Khurram

You need to tell it where to find the engine as well.  libcrypto looks
in the standard system places (typically /usr/lib or so) and the path
given by the environment variable OPENSSL_ENGINES.  Try these lines
and see if that makes a difference:

OPENSSL_ENGINES=.
export OPENSSL_ENGINES
openssl pkeyutl -encrypt -in message.txt -pubin -inkey pubkey-B.pem -engine 
rsa_engine -out cipher.bin
openssl pkeyutl -decrypt -in cipher.bin -inkey privkey-B.pem -engine rsa_engine 
-out rec.txt

Cheers,
Richard
