Nmap NSE 库分析 >>> base64

0x00 简介

base64 这个库就两个函数方法，一个加密一个解密很好理解

0x01 方法实战

enc 函数只有一个参数 p，为要编码的数据

local url = require "url"
local stdnse = require "stdnse"
local base64 = require "base64"

description = [[
This is a test for http.lua's functions

author = "test94"

categories = {"default"}

prerule = function()
    print("functest running")
end
portrule = function () return true end --shortport.http

action = function(host, port)
    local output = stdnse.output_table()
    local demo = "abc123"
    local result = base64.enc(demo)
    output.result = result
    return output
end

测试一下

只有一个参数，要被解密的数据
