des加密 lua

分享2种openresty des3加密的代码，节省大家脱坑的时间：

1.based on lua-resty-nettle

local pkcs7 = require "restytle.padding.pkcs7"

local base64 = require "restytle.base64"

local des = require "restytle.des"

local cipher= des.new("密钥")

local encrypted = cipher:encrypt(pkcs7.pad('要加密的文本', 8))

ngx.print(base64.encode(encrypted))

2.based on lua-lockbox

local Array = require("lockbox.util.array")

local Stream = require("lockbox.util.stream")

local ECBMode = require("lockbox.cipher.mode.ecb")

local PKCS7Padding = require("lockbox.padding.pkcs7")

local DESCipher = require("lockbox.cipher.des3")

local Base64 = require("lockbox.util.base64")

local cipher = ECBMode.Cipher().setKey(Array.fromString("密钥")).setBlockCipher(DESCipher).setPadding(PKCS7Padding)

local res = cipher.init().update(Stream.fromArray(Array.fromString(""))).update(Stream.fromArray(Array.fromString('要加密的文本'))).finish().asBytes()

local out = Base64.fromArray(res)

ngx.print(out)

推荐第1种,性能还可以,lua-lockbox需要修改lockbox.padding.pkcs7中的一行代码local paddingCount = blockSize - byteCount % blockSize;
