Generate public and private keys with OpenSSL under Mac

Generate public and private keys with OpenSSL under Mac

MAC OS comes with OpenSSL, so you don't have to compile the same source code as shit. You can use OpenSSL directly on the command line.

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

Sticker Code No Nonsense
