Mac OS X生成RSA公钥和私钥

生成私钥

genrsa -out rsa_private_key.pem 1024

生成公钥

rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem

如下

df@DFdeMacBook-Pro yzx % mkdir RSAkey
df@DFdeMacBook-Pro yzx % cd RSAkey
df@DFdeMacBook-Pro RSAkey % sudo apt-get install openssl
Password:
sudo: apt-get: command not found
df@DFdeMacBook-Pro RSAkey % brew install openssl
zsh: command not found: brew
df@DFdeMacBook-Pro RSAkey % openssl
