Asymmetric Cryptography using openssl lib

[Mohammad Khodaei]

Hello,

I am a bit confused when it comes to asymmetric encryption/decryption. Now
I use PKCS7_encrypt() and PKCS7_decrypt() to encrypt using recipient public
key and decrypt using the private key. My question is that if they the
correct functions to encrypt and decrypt? Or they are supposed to be used
for only PKCS7 enveloped Data Structure?

Thanks
