BlowFish加解密原理与代码实现

一丶简介

BlowFish 是一个对称加密的加密算法。由 Bruce Schneier，1993年设计的。是一个免费自由使用的加密算法。

了解的必要知识

BlowFish是一个对称区块加密算法。每次加密数据为 64位 （2个int)类型数据大小。八个字节

BlowFish 密钥采用32-448位

BlowFish是由一个16轮循环的Feistel结构进行加密的。

二丶原理与代码介绍

2.1 BlowFish算法流程

BlowFish 算法流程是由两部分组成分别是密钥扩展以及数据加密

在数据加密中是一个16轮循环的Feistel网络。每一轮由一个密钥相关置换和一个密钥与数据相关的替换组成的。

先说一下BlowFish需要的子密钥。

BlowFish在加密或者初始化的过程中会使用两个盒来进行加密

分别是PBOX 以及SBOX

PBOX是由18个32位的字的子密钥组成的。这些密钥可以通过预计算产生的。

其中PBOX记录的就是Π后面的小数位。转换成16进制存储到pBox中

例如：

p[0] = 0x243F6A88
P[1] = 0X85A308D3
P[2] = 0X13198A2E
P[3] = 0X03707344

p[0] = 0x243F6A88

P[1] = 0X85A308D3

P[2] = 0X13198A2E

P[3] = 0X03707344

关于数学中Π大家应该知道。这里不再累赘。关于如何计算Π后面的小数位以及将小数位转为十六进制存储到p[0]---p[18] 这里也不再赘述。因为这些都是预计算好的。我们直接使用就可以。

关于小数转为16进制可以使用网站进行转换（不确保以后还能否使用）：小数转换16进制

例子如下：

Sbox跟PBOX一样也是Π的小数位组成。sBox是4组8*32的数组。如下

s_box[4][256] = {{},{},{},{}};

1	s_box[4][256] = {{},{},{},{}};

pBox与Sbox就是BlowFish算法进行加密的核心置换表

2.2 子密钥生成

如果想进行数据加密。那么我们就要进行子密钥生成。也就是要将我们的Key 与 pbox进行异或

那么说一下流程吧

1.按顺序使用Π的小数部分初始化pbox与sbox （预先计算好了可以直接使用）

2.使用key参数得出key_pbox，具体流程为将pbox中的数据与 key进行 ^ 然后设置到key_pbox中，轮询key每次取出四个字节来与pbox[i]进行异或

如果Key不足的情况下 key从零开始补齐4个字节继续与pbox[i]进行异或

例子：

伪代码：
设key为 “IBinary" key长度为：7
循环18次 
key_pbox[0] = pbox[0] ^ (DWORD)"IBin"  使用4个字节存储
key_pbox[1] = pbox[1] ^ (DWORD)"aryI"  重新使用key的第一个字节补齐
key_pbox[17] = pbox[17] ^(DWORD)"xxxx" 一直到18轮

伪代码：

设key为 “IBinary" key长度为：7

循环18次

key_pbox[0] = pbox[0] ^ (DWORD)"IBin" 使用4个字节存储

key_pbox[1] = pbox[1] ^ (DWORD)"aryI" 重新使用key的第一个字节补齐

key_pbox[17] = pbox[17] ^(DWORD)"xxxx" 一直到18轮

3.使用当前的key_pbox数组与s_box数组对一个64位0数据进行加密。也就是两个int 类型数据 8个字节输出的结果重新修改到key_pbox 与 key_sbox中。

key_sbox就是当前的使用s_box对64位数据进行加密，产生的输出修改的key_sbox中。

行循环4 列循环256
加密(data1,data2)
key_sbox[0] = data1
key_sbox[1] = data2
第二轮循环
加密（data1,data2)
key_sbox[2] = data1
key_sbox[2] = data2;

行循环4 列循环256

加密(data1,data2)

key_sbox[0] = data1

key_sbox[1] = data2

第二轮循环

加密（data1,data2)

key_sbox[2] = data1

key_sbox[2] = data2;

一直循环直到修改完key_pbox与key_sbox为止

示例代码如下：

#define N 16
//定义初始化需要用到的加密结构
typedef struct _BLOWFISH_CTX
{
    //定义初始化的pbox 以及 sbox 在程序中进行初始化
    unsigned int pbox[N + 2];  //总共18
    unsigned int sbox[4][256];
}BLOWFISH_CTX,*PBLOWFISH_CTX;
 
bool BlowFishInit(BLOWFISH_CTX* blowCtx, unsigned char * key, unsigned int keylen)
{
    //第一步初始化Sbox的值 sbox是预先生成的。在全局区是 ORIG_S 数组
    for (int Row = 0; Row < 4; Row++)
    {
        for (int Col = 0; Col < 256; Col++)
        {
            blowCtx->sbox[Row][Col] = ORIG_S[Row][Col];
        }
    }
 
    /*

    int KeyIndex = 0;
    for (int index = 0; index < N + 2; index++)
    {
        unsigned int data = 0;
        //填充data 将key的字符设置到data当中
        for (int k = 0; k < 4; k++)
        {
            //通过移位设置每个字符
            data = (data << 8) | key[KeyIndex];
            KeyIndex++;
            //如果超出了key长度 那么key要从开始
            if (KeyIndex >= keylen)
                KeyIndex = 0;
        }
        //这是时设置key_pbox的值。 原理就是 pbox ^ data  data就是我们的第二层循环。 就是获取四字节的key值 如果你的key只有四个字节。那么
        //都可以不使用第二层循环了
        blowCtx->pbox[index] = ORIG_P[index] ^ data;
    }
 
    /*

    */
    
    unsigned int Data1 = 0;
    unsigned int Data2 = 0;
    for (int i = 0; i < N + 2; i+=2)
    {
        BlowFish_Encry(blowCtx, &Data1, &Data2);
        blowCtx->pbox[i] = Data1;
        blowCtx->pbox[i+1] = Data2;
    }
    //初始化Sbox
    for (int i = 0; i < 4; i++)
    {
        for (int j = 0; j < 256; j += 2)
        {
            BlowFish_Encry(blowCtx, &Data1, &Data2);
            blowCtx->sbox[i][j] = Data1;
            blowCtx->sbox[i][j + 1] = Data2;
        }
    }
    return true;
}

#define N 16

//定义初始化需要用到的加密结构

typedef struct _BLOWFISH_CTX

{

//定义初始化的pbox 以及 sbox 在程序中进行初始化

unsigned int pbox[N + 2]; //总共18

unsigned int sbox[4][256];

}BLOWFISH_CTX,*PBLOWFISH_CTX;

bool BlowFishInit(BLOWFISH_CTX* blowCtx, unsigned char * key, unsigned int keylen)

{

//第一步初始化Sbox的值 sbox是预先生成的。在全局区是 ORIG_S 数组

for (int Row = 0; Row < 4; Row++)

{

for (int Col = 0; Col < 256; Col++)

{

blowCtx->sbox[Row][Col] = ORIG_S[Row][Col];

}

第二步子密钥生成设置key_Pbox

设置pbox

1.循环18轮

2.每轮都设置ctx.pbox值与data ^

3.data = *(DWORD*)key[0] key[1].....

data其实就是4字节转换的Ascii值

设key = "IBinary"

data = "IBin" 类似于 memcpy(&data,"IBin",4);

当key不足的时候重新从头开始获取并且补足

int KeyIndex = 0;

for (int index = 0; index < N + 2; index++)

{

unsigned int data = 0;

//填充data 将key的字符设置到data当中

for (int k = 0; k < 4; k++)

{

//通过移位设置每个字符

data = (data << 8) | key[KeyIndex];

KeyIndex++;

//如果超出了key长度那么key要从开始

if (KeyIndex >= keylen)

KeyIndex = 0;

}

//这是时设置key_pbox的值。原理就是 pbox ^ data data就是我们的第二层循环。就是获取四字节的key值如果你的key只有四个字节。那么

//都可以不使用第二层循环了

blowCtx->pbox[index] = ORIG_P[index] ^ data;

}

第三步设置key_pbox 与 key_sbox的值

1.对一个64位0 进行加密。加密结果的输出设置到pbox[i]与pbox[i+1]中

2.初始化key_pbox之后继续重用Data1与Data2 继续进行加密设置到s_box中

unsigned int Data1 = 0;

unsigned int Data2 = 0;

for (int i = 0; i < N + 2; i+=2)

{

BlowFish_Encry(blowCtx, &Data1, &Data2);

blowCtx->pbox[i] = Data1;

blowCtx->pbox[i+1] = Data2;

}

//初始化Sbox

for (int i = 0; i < 4; i++)

{

for (int j = 0; j < 256; j += 2)

{

BlowFish_Encry(blowCtx, &Data1, &Data2);

blowCtx->sbox[i][j] = Data1;

blowCtx->sbox[i][j + 1] = Data2;

}

return true;

}

2.3 加密原理

BlowFish加密很简单。就是将一个数拆分为左右各32位数值（也就是 8个字节左边四个字节，右边四个字节）然后左边进行 ^ key_pbox 当作下一次循环的右边。右边则是右边 ^ F(左边) 下次当作循环的左边。

循环16轮。

说着挺难。看下图：

简单的加密流程图：

在这里我们只看加密

原理就三行重要代码 循环16次
R = L ^ Key_pbox[i]
L = F(R) ^ L
swap(R,L);
最后一轮单独设置介绍完F之后继续说

原理就三行重要代码循环16次

R = L ^ Key_pbox[i]

L = F(R) ^ L

swap(R,L);

最后一轮单独设置介绍完F之后继续说

这里不得不介绍下F函数。 F函数的输入是一个32位数也就是四个字节类型数据。然后内部就是将32位数进行拆分成abcd

例如：

data = 0x12345678
 
拆分后
a = 0x12
b = 0x34
c = 0x56
d = 0x78

data = 0x12345678

拆分后

a = 0x12

b = 0x34

c = 0x56

d = 0x78

拆分后的a b c d然后去Key_sbox中查表然后取出对应的值。

公式如下：

((s1,a + s2,b) ^ s3,c) + s4,d
对应数组操作就是
value = key_sbox[0][a] + Key_sbox[1][b]
value  = value ^ key_sbox[2][c]
Value = value + Key_sbox[3][d]
公式是从s1a s2b s3c s4d开始的。 数组下标是从0开始的。所以s1对应的就是 Key_sbox[0] 后面依次类推。
最后返回Value
公式简单记一下就是 return (((a + b) ^ c) + d)

((s1,a + s2,b) ^ s3,c) + s4,d

对应数组操作就是

value = key_sbox[0][a] + Key_sbox[1][b]

value = value ^ key_sbox[2][c]

Value = value + Key_sbox[3][d]

公式是从s1a s2b s3c s4d开始的。数组下标是从0开始的。所以s1对应的就是 Key_sbox[0] 后面依次类推。

最后返回Value

公式简单记一下就是 return (((a + b) ^ c) + d)

F函数明白了那么回头继续看一下加密操作。

图如下：

可以看到首先计算 L ^Kr(Key_pbox[i]) 然后结果直接作为下一轮的右侧

右侧则是经过论函数F 进行设置的。最后变为下一轮循环的左侧。

R = R ^F（L）

最后一轮的话需要单独设置

R = R ^ Key_pbox[16]  //数组中下标16就代表17
L = L ^ Key_pbox[17]  //同上这里是代表下标18

1 2	R = R ^ Key_pbox[16] //数组中下标16就代表17 L = L ^ Key_pbox[17] //同上这里是代表下标18

其实加密函数就是循环16次。然后每一轮都对左侧32位右侧32位进行操作。操作之后直接作为下一轮循环的左右侧

核心代码如下：

void BlowFish_Encry(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right)
{
    unsigned long  Xl;
    unsigned long  Xr;
    unsigned long  temp;
    short       i;
 
    //第一步 获取左右侧的数据 每组32位
    Xl = *left;
    Xr = *right;
 
	//第二部进行16轮的加密 最后交换xl xr 作为下一轮循环的左右侧
    for (i = 0; i < N; ++i) {
        Xl = Xl ^ blowCtx->pbox[i];
        Xr = F(blowCtx, Xl) ^ Xr;
 
        temp = Xl;
        Xl = Xr;						//交换左右的值。 l = R r= l 继续下一轮循环。总共16轮
        Xr = temp;
    }
 
	//第三步 进行16轮循环之后我们需要特殊操作。 最后直接设置xr 与xr即可。 
    temp = Xl;
    Xl = Xr;                          //16轮完毕之后交换变量
    Xr = temp;
 
    Xr = Xr ^ blowCtx->pbox[N];              //最后进行一次疑或
    Xl = Xl ^ blowCtx->pbox[N + 1];
 
    *left = Xl;
    *right = Xr;
}

void BlowFish_Encry(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right)

{

unsigned long Xl;

unsigned long Xr;

unsigned long temp;

short i;

//第一步获取左右侧的数据每组32位

Xl = *left;

Xr = *right;

//第二部进行16轮的加密最后交换xl xr 作为下一轮循环的左右侧

for (i = 0; i < N; ++i) {

Xl = Xl ^ blowCtx->pbox[i];

Xr = F(blowCtx, Xl) ^ Xr;

temp = Xl;

Xl = Xr; //交换左右的值。 l = R r= l 继续下一轮循环。总共16轮

Xr = temp;

}

//第三步进行16轮循环之后我们需要特殊操作。最后直接设置xr 与xr即可。

temp = Xl;

Xl = Xr; //16轮完毕之后交换变量

Xr = temp;

Xr = Xr ^ blowCtx->pbox[N]; //最后进行一次疑或

Xl = Xl ^ blowCtx->pbox[N + 1];

*left = Xl;

*right = Xr;

}

至此我们的blowFish加密已经完成

2.4 BlowFish的解密

解密与加密是相反操作。加密的时候是从0开始遍历16轮然后依次对xl xr进行操作。

解密的时候做事从16开始然后迭代16轮对左右两侧做操作

最后16轮循环完毕之后还是进行一次^

代码如下：

void BlowFish_Decrypt(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right)
{
    unsigned int Xl = *left;
    unsigned int Xr = *right;
 
    //倒着循环
    for (int i = N + 1; i > 1; --i)
    {
        Xl = Xl ^ blowCtx->pbox[i];
        Xr = Xr ^ F(blowCtx, Xl);
        
        //继续左右交换
        unsigned int temp = Xl;
        Xl = Xr;
        Xr = temp;
    }
 
    //最后一轮继续交换
    unsigned int temp = Xl;
    Xl = Xr;
    Xr = temp;
 
    //返还原
    Xr = Xr ^ blowCtx->pbox[1];
    Xl = Xl ^ blowCtx->pbox[0];
 
    //设置变量返回
    *left = Xl;
    *right = Xr;
}

void BlowFish_Decrypt(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right)

{

unsigned int Xl = *left;

unsigned int Xr = *right;

//倒着循环

for (int i = N + 1; i > 1; --i)

{

Xl = Xl ^ blowCtx->pbox[i];

Xr = Xr ^ F(blowCtx, Xl);

//继续左右交换

unsigned int temp = Xl;

Xl = Xr;

Xr = temp;

}

//最后一轮继续交换

unsigned int temp = Xl;

Xl = Xr;

Xr = temp;

//返还原

Xr = Xr ^ blowCtx->pbox[1];

Xl = Xl ^ blowCtx->pbox[0];

//设置变量返回

*left = Xl;

*right = Xr;

}

至此解密完成

(（s1[a] + s2[b]) ^ s3[c]) + s4[d]
在编程中sbox是数组是从零开始。 所以s1 对应s[0]  s2对应s[1]
在编程中总结下公式：
 
temap = s[0][a] + s[1][b]
teamp = temp ^ s[2][c]'
temp =  temp + s[3][d]
简单的记住就是 ((a+b) ^ c)+d;
当然每个都对应下标为 0 1 2 3  s[0][a] s[1][b] s[2][c] s[3][d]
最后返回结果值 return temp

左边数据直接 ^ PBOX
右边数据 = 右边数据 ^ f(左边数据）
然后进行交换。
以上是16轮的交换
剩下一轮则是 
 
左边 = 左边^PBOX[N+1]
右边 = 右边^pbox[N]
最后设置相关数值

#define N 16

//定义初始化需要用到的加密结构

typedef struct _BLOWFISH_CTX

{

//定义初始化的pbox 以及 sbox 在程序中进行初始化

unsigned int pbox[N + 2]; //总共18

unsigned int sbox[4][256];

}BLOWFISH_CTX,*PBLOWFISH_CTX;

初始化函数此函数功能如下

1.接受key 与 keylen参数（当然keylen）可以自己计算

2.初始化sbox 将全局的sbox的内容复制到CTX中的sbox中

3.初始化pbox pbox的初始化方法如下

1.迭代18论。然后每一轮都设置CTX的pbox

2.CTX.pbox需要使用全局pbox ^ data

3.data是一个四字节整数。其中存储的就是key的四个字节。

key = "12345678abc"

每一轮中 data = "1234"

data = "5678"

data = "abc1" //注意这里当超出keylen的时候。 data获取的key要从0开始

。。。。

bool BlowFishInit(BLOWFISH_CTX* blowCtx, unsigned char*key, unsigned int keylen);

F函数

F函数是将一个32位数分别进行拆分。拆分为四组。每一组都作为sbox的索引值

然后进行下列运算

(（s1[a] + s2[b]) ^ s3[c]) + s4[d]

在编程中sbox是数组是从零开始。所以s1 对应s[0] s2对应s[1]

在编程中总结下公式：

temap = s[0][a] + s[1][b]

teamp = temp ^ s[2][c]'

temp = temp + s[3][d]

简单的记住就是 ((a+b) ^ c)+d;

当然每个都对应下标为 0 1 2 3 s[0][a] s[1][b] s[2][c] s[3][d]

最后返回结果值 return temp

static unsigned long F(BLOWFISH_CTX* ctx, unsigned long x);

//signed int F(PBLOWFISH_CTX blowCtx,unsigned int Data);

加密函数：

首次用在初始化中是对一个64位0进行加密。

一次加密八个字节

核心思想为加密左边与右边数据

左边数据直接 ^ PBOX

右边数据 = 右边数据 ^ f(左边数据）

然后进行交换。

以上是16轮的交换

剩下一轮则是

左边 = 左边^PBOX[N+1]

右边 = 右边^pbox[N]

最后设置相关数值

void BlowFish_Encry(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right);

跟加密一样。只不过结果相反步骤如下：

首先遍历从最后一轮开始逐次递减

最后一轮数据右边= 右边^PBOX[1] 左边数据 = 左边数据 ^pbox[0]

void BlowFish_Decrypt(PBLOWFISH_CTX blowCtx, unsigned int* left, unsigned int* right);

Windows 11 Version 21H2 更新提示 “你的设备缺少重要的安全更新。”

最近 (2024/12/24) 家里的电脑在 Windows 更新界面提示 “你的设备缺少重要的安全更新。请确保设备保持打开状态并接通电源，以便更新可以完成。”

如下图：

不管如何点击刷新重试，都会出现上述提示。

系统版本为 Windows 11 Version 21H2，详细信息参考下图：

原因为 Windows 11 Version 21H2 已经在 2023/10/10 终止服务，所以已经无法更新系统补丁。如下图：

解决方法就是安装依旧提供支持的系统版本 Windows 11 Version 23H2 或者 Windows 11 Version 24H2 。

需要注意的是，升级到 24H2 无法保留已经安装的软件，因此当前 (2024/12/24) 只能升级到 23H2 。

对于不支持的硬件进行升级安装，可以通过 Rufus 写入到 U盘后，不重启电脑，直接点击 U 盘上的安装文件进行安装，可以正常完成系统升级。

如下图：

点击开始会弹出如下信息，保持信息不变即可，如下图：

Flutter 错误：找不到名为 frontend_server.dart.snapshot 的命令

Caught error: Unsupported operation: Platform._operatingSystem

Flutter 代码运行在 Chrome 上的时候报错 “Caught error: Unsupported operation: Platform._operatingSystem”。

报错的原因是因为代码中使用了 Platform.isIOS、Platform.isAndroid 等函数判断系统类型，可惜的是，这些函数并不能在 Chrome 上运行。

修改方法就是自己封装一个自定义工具类，先使用 kIsWeb 排除一下浏览器。参考如下：

import 'dart:io';

import 'package:flutter/foundation.dart';

class PlatformKit {
  /// 是否是移动设备，如果系统是 Android 、iOS 则返回 true 否则返回 false
  static bool isMobile() {
    return (!kIsWeb) && (Platform.isAndroid || Platform.isIOS);
  }

  /// 是否是macOS，如果系统 macOS 则返回 true 否则返回 false
  static bool isMacOS() {
    return (!kIsWeb) && Platform.isMacOS;
  }
}

import 'dart:io';

import 'package:flutter/foundation.dart';

class PlatformKit {

/// 是否是移动设备，如果系统是 Android 、iOS 则返回 true 否则返回 false

static bool isMobile() {

return (!kIsWeb) && (Platform.isAndroid || Platform.isIOS);

}

/// 是否是macOS，如果系统 macOS 则返回 true 否则返回 false

static bool isMacOS() {

return (!kIsWeb) && Platform.isMacOS;

Flutter Web 警告 Local variable for "serviceWorkerVersion" is deprecated

升级到 Flutter 3.22.0 之后，在 Chrome 上运行 Flutter Web 应用程序时收到以下警告：

Launching lib/main.dart on Chrome in debug mode...
Waiting for connection from debug service on Chrome...
Warning: In index.html:40: Local variable for "serviceWorkerVersion" is deprecated. Use "{{flutter_service_worker_version}}" template token instead. See https://docs.flutter.dev/platform-integration/web/initialization for more details.

Launching lib/main.dart on Chrome in debug mode...

Warning: In index.html:40: Local variable for "serviceWorkerVersion" is deprecated. Use "{{flutter_service_worker_version}}" template token instead. See https://docs.flutter.dev/platform-integration/web/initialization for more details.

这个警告的原因是，新版本的 Flutter Web 应用加载 service_worker.js 的方式发生了变化，原来的加载脚本被 {{flutter_bootstrap_js}} 替代。

调整为新的初始化代码即可解决此问题。
