为什么我的crypt包会给我无效的魔术前缀错误? [英] Why does my crypt package give me invalid magic prefix error?

问题描述

我有以下代码:

import "github.com/kless/osutil/user/crypt/sha512_crypt"
c := sha512_crypt.New()
hash, err := c.Generate([]byte("enter-new-password"), []byte("$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2"))
if err != nil {
    panic(err)
}

它产生了以下错误

http:紧急服务192.168.0.16:56730:无效的魔术前缀

http: panic serving 192.168.0.16:56730: invalid magic prefix

您的魔术前缀无效.

You have an invalid magic prefix.

github.com/tredoe/osutil/user/crypt/sha512_crypt/sha512_crypt.go

if !bytes.HasPrefix(salt, c.Salt.MagicPrefix) {
  return "", common.ErrSaltPrefix
}

读取crypt软件包代码.

Read the crypt package code.

PHP:crypt —单向字符串散列

PHP:password_hash-创建密码哈希

阅读PHP文档.

请参阅您先前的问题: golang等同于PHP crypt().

See your earlier question: golang equivalent of PHP crypt().

提供有效的魔术前缀.

例如，

package main

import (
    "fmt"

    "github.com/kless/osutil/user/crypt/sha512_crypt"
)

func main() {
    c := sha512_crypt.New()
    magic := sha512_crypt.MagicPrefix
    hash, err := c.Generate(
        []byte("enter-new-password"),
        []byte(magic+"$2a$09$f5561d2634fb28a969f2dO8QeQ70f4bjCnF/.GvPpjj.8jgmtzZP2"),
    )
    if err != nil {
        panic(err)
    }
    fmt.Println(hash)
}

输出:

注意:

import "github.com/kless/osutil/user/crypt/sha512_crypt"

现在是新位置的别名

import "github.com/tredoe/osutil/user/crypt/sha512_crypt"
