Example with XOR algorithm for reversible encryption, 用异或算法进行可逆加密算法范例

pwd_test.go

package tests

import (
	"fmt"
	"testing"
)

// 可逆加密简单算法测试，采用异或方式
func TestPwd(t *testing.T) {
	pwd := "Hello world!"
	key := "test"

	pwdBytes := []byte(pwd)
	keyBytes := []byte(key)
	hashBytes := []byte{}
	cpwdBytes := []byte{}
	keyLen := len(keyBytes)

	var cpwd string

	for i, v := range pwdBytes {
		hashBytes = append(hashBytes, v^keyBytes[i%keyLen])//获得密码和key的异或值
	}

	fmt.Println("hashBytes: ", hashBytes)
	fmt.Println("hashPwdStr: ", string(hashBytes))

	for i, v := range hashBytes {
		cpwdBytes = append(cpwdBytes, v^keyBytes[i%keyLen])//通过key与异或值 异或，得到密码值
	}

	cpwd = string(cpwdBytes)

	fmt.Println("cpwdBytes: ", cpwdBytes)
	fmt.Println("pwd: ", cpwd)
}
