MAC generates public key private key

Objective

Requires developers to use OpenSSL locally to generate private and public keys

Because the Mac comes with the OpenSSL tool, you don't have to download the OpenSSL tool like Windows

Step 1. Create a folder where the terminal enters the folder

Cd/users/tanqihong/desktop/rsa

2. Terminal input OpenSSL open tool 3. Generate RSA private key

Genrsa-out RSA_PRIVATE_KEY.PEM 1024

The command generates a 1024-bit private key, which generates a successful interface as follows:

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

4. Convert RSA private key to PKCS8 format

Input command Pkcs8-topk8-inform pem-in rsa_private_key.pem-outform pem–nocrypt, and enter

Enter the password, enter, verify the password, enter
The result of a successful birth is a private key in the PKCS8 format, such as:

5. Generating the RSA public key

Enter command rsa-in rsa_private_key.pem-pubout-out Rsa_public_key.pem, and enter,
Get the results of a successful build, such as:

6. Exit Exit7. To view the folder, change the. pem file inside to a TXT file to see what's inside.
