random_encrypt
基于openssl加密
仅使用了 AES-128-CBC
根据时间戳所在的时间区间，时区信息计算加密的key，iv
为每个key设置有效时间(默认5秒，冗余2秒)，在不同的时间区间（左包右闭），相同文本加密后的字符串不同
默认时区为东八区，加密端和解密端通过统一时区对齐时间，避免不同时区，同时间段，加密后的密文不同，导致无法解密
在使用时，必须自定义盐值，不能为空。if e.salt == "" { panic("the salt can not be empty") }
Encrypt函数返回 (加密后字符串,key,iv,加密时使用的时间戳) 供解密失败后备查。
Install
go get -u github.com/siburuxue/go_random_encrypt
示例代码：
config := map[string]interface{}{"salt": "salt"}
e := random_encrypt.NewRandomEncrypt(config)
s, key, iv, timestamp := e.Encrypt("hello world")
fmt.Println(s)
fmt.Println(key)
fmt.Println(iv)
fmt.Println(timestamp)
t := e.Decrypt(s)
fmt.Println(t)
