介绍
在openresty上使用国密算法SM4
在使用源参考地址过程中，发现最后得出的结果似乎不是预期想要的，故对最后加密encrype和解密decrypt方法中做了修改，另源仓库已经存档 没办法提issues和pr了
快速使用
实际使用过程中请注意是否将对应文件放在resty目录下，若不是 请修改require为对应导入的包路径
local resty_sm4 = require "resty.sm4"
local key = '1234567890abcdef'
local text = 'test'
local sm4 = resty_sm4:new(key)
# 加密
local en_text = sm4:encrypt(text)
print(en_text)
#解密
local de_text = sm4:decrypt(text)
print(en_text)License
