window与linux要区分的

 

解压文件

 

双击:

六、运行“nmake -f msntdll.mak install”安装编译后的OpenSSL到指定目录。

Win32OpenSSL-0_9_8l_95895.exe

七、查看安装结果C:usrlocalssl或C:openssl-0.9.8.e下包含了三个文件夹Bin、include、lib。bin下包括openssl.exe(openssl指令程序)、ssleay32.dll(ssl协议动态库)、libeay32.dll(密码算法库)。lib下包括libeay32.lib,ssleay32.lib。Include目录包括了OpenSSL开发设计的头文件。

安装完毕后

  至此,OpenSSL在windows下编译完成了。

OpenSSLbinopenssl.exe

最后一步编译时可能出现错误:“NMAKE : fatal error U1077: 'ml' : return code '0x1' Stop.”,产生这种错误的可能原因是vc6的bin目录下没有ml.exe这个文件。该文件包含在MASM程序中。我的解决办法是到网上下载了一个MASM程序(http://www.masm32.com/masmdl.htm),安装上之后把ml.exe拷贝到VC6的bin目录下即可解决。

输入命令,生成私钥

二.生成证书和秘钥

打开openssl.exe文件输入命令

  1. 生成RSA密钥的方法

key一般分为public key和private key,在openssl中,private key中包含了public key的信息,所以public key不需要单独创建. 如何创建一个RSA key?

openssl.exe genrsa -des3 -out privkey.pem 2048  (需要添加密码保护)

这个命令会生成一个2048位的密钥,同时有一个des3方法加密的密码,如果你不想要每次都输入密码,可以改成:

openssl.exe genrsa -out privkey.pem 2048

建议用2048位密钥,少于此可能会不安全或很快将不安全。

 

  1. 生成一个证书请求

openssl req -new -key privkey.pem -outcert.csr

这个命令将会生成一个证书请求,当然,用到了前面生成的密钥privkey.pem文件

这里将生成一个新的文件cert.csr,即一个证书请求文件。

 

  1. 生成证书

   拿到上面的证书请求文件,去数字证书颁发机构(即CA)申请一个数字证书。CA会给你一个新的文件cacert.pem,那才是你的数字证书。

 

   如果是自己做测试,那么证书的申请机构和颁发机构都是自己。就可以用下面这个命令来生成证书:

    openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095

   这个命令将用上面生成的密钥privkey.pem生成一个数字证书cacert.pem

genrsa -out private-rsa.pem

openssl 生成自签证书

博客分类:

  • linux

 

在要生成证书的目录下建立几个文件和文件夹,有./demoCA/ ./demoCA/newcerts/  ./demoCA/index.txt ./demoCA/serial,在serial文件中写入第一个序列号“01” 

1.生成X509格式的CA自签名证书 
$openssl req -new -x509 -keyout ca.key -out ca.crt 

2.生成服务端的私钥(key文件)及csr文件 
$openssl genrsa -des3 -out server.key 1024 
$openssl req -new -key server.key -out server.csr 

3.生成客户端的私钥(key文件)及csr文件 
$openssl genrsa -des3 -out client.key 1024 
$openssl req -new -key client.key -out client.csr 

4.用生成的CA的证书为刚才生成的server.csr,client.csr文件签名 
$openssl ca -in server.csr -out server.crt -cert ca.crt -keyfile ca.key 
$openssl ca -in client.csr -out client.crt -cert ca.crt -keyfile ca.key 

5.生成p12格式证书 
$openssl pkcs12 -export -inkey client.key -in client.crt -out client.pfx 
$openssl pkcs12 -export -inkey server.key -in server.crt -out server.pfx 

6.生成pem格式证书 
有时需要用到pem格式的证书,可以用以下方式合并证书文件(crt)和私钥文件(key)来生成 
$cat client.crt client.key> client.pem 
$cat server.crt server.key > server.pem 

7.PFX文件转换为X509证书文件和RSA密钥文件 
$openssl pkcs12 -in server.pfx -nodes -out server.pem 
$openssl rsa -in server.pem -out server2.key 
$openssl x509 -in server.pem -out server2.crt 

这样生成服务端证书:ca.crt, server.key, server.crt, server.pem, server.pfx,客户端证书:ca.crt, client.key, client.crt, client.pem, client.pfx
