WebApr 14, 2014 · Just use an Integrated Encryption Scheme like ECIES or DLIES/DHAES. The integrated schemes use public key crypto, utilize symmetric bulk encryption and provide the authentication tags. Because the authentication tags are built into the scheme, you will not need a separate signer. – jww Apr 17, 2014 at 5:08 Show 8 more comments … WebC++ NaCl provides a crypto_box_keypair function callable as follows: #include "crypto_box.h" std::string pk; std::string sk; pk = crypto_box_keypair (&sk); The crypto_box_keypair function randomly generates a secret key and a corresponding public key. It puts the secret key into sk and returns the public key.
