Principle: OpenSSL has an open source project on GitHub and we just need to clone the code locally and compile it locally.Precautions:1-> on GitHub to get the source code, you have to install git for Windows, URL Https://git-for-windows.github.ioThe
Because of the needs of the experiment, you need to manually create the CA certificate and the client and server certificates, which are summarized as follows: In the last two days, you have read some information about certificate creation, I found
Because you need to test Nginx spdy, you need to upgrade OpenSSL. May involve subsequent large-scale upgrade plans, so the OpenSSL is made into RPM packages, which includes the management of HIFN so.The management of HIFN so is:Copy so to/usr/lib

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
The Linux command generates the public and private keys directly using the OpenSSL command, as described in the OpenSSL command# Generate 1024 bits RSA private key, encrypt it with 3DES, password for 123,# output to file rsa_private_key.pem# OpenSSL
