在dao/mysql/user.go中有这样一段代码:
const secret = "liwenzhou.com"
func encryptPassword(data []byte) (result string) {
h := md5.New()
h.Write([]byte(secret))
return hex.EncodeToString(h.Sum(data))
}
h.Sum(data)的源码实现是先将直接将secret的MD5切片数组拼接到data切片数组后面,随后通过hex.EncodeToString转换成十六进制的字符串,这样返回的加密字符串并没有将明文的密码加密,而是返回了一个data字符串长度*2+32 长度的一个字符串。
例如假设data = []byte("123456")
,返回的result就为313233343536639a9119599647d841b1bef6ce5ea293
,去除后32位的字符的结果为:313233343536
,通过十六进制转字符串后的结果就是123456。也就是说,如果有人拿到了数据库中的password字段,就能获取到用户账户的明文信息。
可以修改成如下代码:
const secret = "liwenzhou.com"
func encryptPassword(data []byte) (result string) {
h := md5.New()
h.Write(append([]byte(secret),data...))
return hex.EncodeToString(h.Sum(nil))
}
这样返回的密文固定为32位字符串了。
前端的库版本能升级一下吗
db: bluebell_pre 应该改为 db: bluebell
