HI Harald, ThanQ for your information. So implementing of PKCS#7 Api's will serve my purpose .. Ok, at last , a small doubt : I have implemented signing, encryption using RSA_sign EVP_EncryptUpdate RSA_public_encrypt , so where these will differ from the PKCS#7 API's as these PKCS#7 api's also do the same things as by the above functions. I did not find any difference of usage of those two. can you please tell me what is difference in b/w usage of those two.
