1) Generate RSA key:

$ openssl genrsa -out key.pem 1024
$ openssl rsa -in key.pem -text -noout
2) Save public key in pub.pem file:

$ openssl rsa -in key.pem -pubout -out pub.pem
$ openssl rsa -in pub.pem -pubin -text -noout
3) Encrypt some data:

Testing SSL (LetsEncrypt certificate and loopback domain)

General approach

This sets up a publically-available domain that loops back to localhost IP address 127.0.0.1. For example, this address could be localhost.example.com if we controlled the example.com domain. This relies on having a public domain name whose DNS records you can control. We can then generate LetsEncrypt certificates for this domain.

Our HTTP server runs on localhost:80 (default HTTP port). This lets us visit http://localhost.example.com in a web browser and see the server running on localhost:80.

We then run an HTTPS proxy server on localhost:443 (default HTTPS port) that uses the LetsEncrypt certificates we generated for localhost.example.com. Visiting https://localhost.example.com hits the proxy, which returns the correct certificates meaning the browser displays the "Secure" message. The proxy then passes the request through to the HTTP server.

// get password's md5 hash
let password = 'test';
let password_hash = crypto.createHash('md5').update(password, 'utf-8').digest('hex').toUpperCase();
console.log('key=', password_hash); // 098F6BCD4621D373CADE4E832627B4F6

第一步，创建一个存放备份的文件夹：

比如 mkdir /alidata/backup

第二步，新建一个自动备份的脚本：

#!/bin/sh
NAME='mxlzb' # 手动修改为待备份项目的数据库名
DATE=`date +%Y%m%d%H%M%S`

If you run bcdedit with no arguments, you should see a property called hypervisorlaunchtype. This will be set to off or auto.

To disable Hyper-V in order to use VirtualBox, open a command prompt as administrator and run the command:

bcdedit /set hypervisorlaunchtype off

You’ll need to reboot, but then you’ll be all set to run VirtualBox. To turn Hyper-V back on, run:

bcdedit /set hypervisorlaunchtype auto
