Use OPENSSL to generate public and private keys under MAC

MAC OS comes with OpenSSL, so there is no need to compile the same source code as SHIT. Just use OPENSSL directly from the command line.

Open the command line tool, then enter openssl to open openssl, and then you can get it done with just three commands. The first command generates a private key; the second command converts the RSA private key into PKCS8 format, and the password is empty; the third command generates a public key.

No nonsense when posting code
