How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

##ss-redir 的 iptables 配置(透明代理)

透明代理指对客户端透明，客户端不需要进行任何设置就使用了网管设置的代理规则

创建 /etc/ss-redir.json 本地监听 7777 运行ss-redir -v -c /etc/ss-redir.json

iptables -t nat -N SHADOWSOCKS
# 在 nat 表中创建新链
iptables -t nat -A SHADOWSOCKS -p tcp --dport 23596 -j RETURN
# 23596 是 ss 代理服务器的端口，即远程 shadowsocks 服务器提供服务的端口，如果你有多个 ip 可用,但端口一致，就设置这个

# Step 1: Fill in EMAIL, TOKEN, DOMAIN and SUBDOMAIN. Your API token is here: https://dash.cloudflare.com/profile/api-tokens
#         Make sure the token is the Global token, or has these permissions: #zone:read, #dns_record:read, #dns_records:edit
#         If you want to set the root domain instead of a subdomain, set SUBDOMAIN to "@"
# Step 2: Create an A record on Cloudflare with the subdomain you chose
# Step 3: Run "./ddns.sh -l" to get the zone_id and rec_id of the record you created.
#         Fill in ZONE_ID and REC_ID below
#         This step is optional, but will save you 2 requests every time you run this script
# Step 4: Run "./ddns.sh". It should tell you that record was updated or that it didn't need updating.
