<p>Respected Mr. Levitte,</p>
<p>I have created the symlink to <span>/usr/lib/x86_64-linux-gnu/openssl-1.0.0/engines/librsa_engine.so. During encryption and decryption it mentions that "<span>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.<br>
</span></span></p>

khurramashraf_786> It seems that it is not using the functions which I defined in the<br>

<br>
You need to tell it where to find the engine as well. libcrypto looks<br>
in the standard system places (typically /usr/lib or so) and the path<br>
given by the environment variable OPENSSL_ENGINES. Try these lines<br>
and see if that makes a difference:<br>
<br>
OPENSSL_ENGINES=.<br>
export OPENSSL_ENGINES<br>
openssl pkeyutl -encrypt -in message.txt -pubin -inkey pubkey-B.pem -engine rsa_engine -out cipher.bin<br>
openssl pkeyutl -decrypt -in cipher.bin -inkey privkey-B.pem -engine rsa_engine -out rec.txt<br>
<br>
Cheers,<br>
Richard<br>
