First, you need to understand some basic concepts before installing 1. Certificates used by SSL can be self-generated or signed by a commercial ca such as Verisign or thawte. 2. Certificate concept: First, you must have a root certificate, and

The current version of OPENSSL-1.0.2J does not support Google's CHACHA20 encryption algorithm. The CHACHA20 encryption algorithm is relatively safe relative to RC4, and is optimized for ARM's mobile phone, making it faster and more
