嵌入式linux开发，MIRACL移植，MIRACL库移植，密码学C语言函数库，SM2椭圆曲线公钥密码算法移植

        MIRACL(Multiprecision Integer and RationalArithmetic C/c++ Library)是一套由Shamus Software Ltd.所开发的一套关于大数运算函数库，用来设计与大数运算相关的密码学之应用，包含了RSA 公开密码学、Diffie-Hellman密钥交换(Key Exchange)、AES、DSA数字签名，还包含了较新的椭圆曲线密码学(Elliptic CurveCryptography)等等。运算速度快，并提供源代码。

一、获取源码并解压。

1、下载。

管网：https://miracl.com/

源码：https://codeload.github.com/miracl/MIRACL/zip/refs/heads/master

下载.zip压缩包，名为MIRACL-master.zip。

2、创建目录。

在与MIRACL-master.zip同一级目录下创建program/arm、program/linux64、program/miracl

mkdir program
cd program
mkdir arm linux64 miracl

3、在program/miracl目录下，解压MIRACL-master.zip。

把所有独立的文件都放在这个目录，即将所有非目录的文件解压在当前目录下。

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ cd miracl
ms@ubuntu:~/ln_work/code/miracl/program/miracl$ unzip -j -aa -L ../../MIRACL-master.zip
Archive:  ../MIRACL-master.zip

replace readme.md? [y]es, [n]o, [A]ll, [N]one, [r]ename: A

二、Ubuntu下编译MIRACL库。

1、编译。

用shell文件编译。如果是64位系统用linux64，如果是32位系统用linux。

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ uname -a
Linux ubuntu 5.4.0-87-generic #98~18.04.1-Ubuntu SMP Wed Sep 22 10:45:04 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
ms@ubuntu:~/ln_work/code/miracl/program/miracl$

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ bash linux64
rm: cannot remove '*.exe': No such file or directory
rm: cannot remove 'miracl.a': No such file or directory
ms@ubuntu:~/ln_work/code/miracl/program/miracl$ 

2、测试。

运行源码提供的示例代码 pk-demo，进行测试。一下是否编译成功。

ms@ubuntu:/ln_work/code/miracl/program/miracl$ ./pk-demo

Alice and Bob's keys should be the same!

Lets try that again using elliptic curves....

3、拷贝库文件。

ms@ubuntu:/ln_work/code/miracl/program/linux64$ cp mirdef.h miracl.h miracl.a ../linux64/

4、使用方法。

gcc -O2 test.c -o test -I./ -L./ miracl.a

三、交叉编译MIRACL库。

        根据参考文档arm.txt，进行操作。

1、修改mirdef.h文件中的内容。

/*
 *   MIRACL compiler/hardware definitions - mirdef.h
 */


#define MIRACL 32
#define MR_LITTLE_ENDIAN      

/* or possibly 
#define MR_BIG_ENDIAN      
*/

#define mr_utype int
#define MR_IBITS 32
#define MR_LBITS 32
#define mr_dltype long long
#define mr_unsign32 unsigned int
#define mr_unsign64 unsigned long long
#define MAXBASE ((mr_small)1<<(MIRACL-1))


#define MR_NOASM

2、创建文件linux-arm，或通过拷贝linux64文件创建。

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ cp linux64 linux-arm

参考arm.txt，拷贝相关内容，并做部分修改调整，内容如下。

rm *.exe
rm miracl.a
#cp mirdef.arm mirdef.h

3、交叉编译，生成静态库。

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ bash linux-arm
rm: cannot remove '*.exe': No such file or directory
rm: cannot remove 'miracl.a': No such file or directory
linux-arm: line 50: arm-linux-link: command not found
ms@ubuntu:~/ln_work/code/miracl/program/miracl$

 4、交叉编译源码提供的示例代码 pk-demo，验证编译是否成功。

arm-linux-gcc -static -o pk-demo.out pk-demo.c -I./ -L./ miracl.a

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ file pk-demo.out
pk-demo.out: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 2.6.16, not stripped
ms@ubuntu:~/ln_work/code/miracl/program/miracl$

5、拷贝文件。

ms@ubuntu:~/ln_work/code/miracl/program/miracl$ cp mirdef.h miracl.h miracl.a ../arm/
ms@ubuntu:~/ln_work/code/miracl/program/miracl$

四、SM2椭圆曲线公钥密码算法移植。

1、管网。

项目文档

SM2椭圆曲线公钥密码

2、代码。

https://download.csdn.net/download/weixin_43782998/32971309

GitHub - guanzhi/GmSSL: 支持国密SM2/SM3/SM4/SM9/ZUC/SSL的OpenSSL分支

3、编译。

编译命令

 gcc -O2 sm2.c sm3.c -o sm2 -I./ -L./ miracl.a

linux64下编译

gcc -O2 sm2.c sm3.c -o sm2-linux64 -I../linux64 -L./ ../linux64/miracl.a

 交叉编译

ms@ubuntu:~/ln_work/code/miracl/program/sm2$ arm-linux-gcc -O2 sm2.c sm3.c -o sm2-arm -I../arm -L./ ../arm/miracl.a
ms@ubuntu:~/ln_work/code/miracl/program/sm2$ file sm2-arm
sm2-arm: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.3, for GNU/Linux 2.6.16, not stripped
