Steps for OpenSSL to generate private key keys

This article refer to http://blog.csdn.net/scape1989/article/details/18959657

If you want to use OpenSSL on Ubuntu, you need to install it first, the command is as follows:

sudo apt-get install OpenSSL

You can use OpenSSL when the installation is complete.

The first step is to enter OpenSSL's interface and enter OpenSSL at the command line;

1) Generate RSA private key:

Genrsa-out RSA_PRIVATE_KEY.PEM 1024

At this point we can see the Rsa_private_key.pem file under the current path.

2) Convert RSA private key to PKCS8 format
Input command Pkcs8-topk8-inform pem-in rsa_private_key.pem-outform pem–nocrypt, and enter

3) Generate RSA public key

Enter command rsa-in rsa_private_key.pem-pubout-out Rsa_public_key.pem, and enter,

At this point, we can see a file named Rsa_public_key.pem, open it, you can see-----begin public Key-----start,
-----End of the public key-----The string with no newline, this is the key.
