openssl安装配置

分类： 系统运维

安装openssl# tar –zxvf openssl# cd openssl# ./config --prefix=/usr/local/openssl# make# make install
加密解密传统加密（对称加密）

openssl enc –ciphername(加密算法) –k password（口令）–in file（被加密的算法） -out （输出文件）file

解密

openssl enc –ciphername –k password-d –in file -out file

加密算法有：base64,des,des3,rc2,rc5,aes256

例如：/bin/openssl enc –des3 –k boobooke –in pt.txt –out ct.bin//加密

/bin/openssl enc –des3 –d–k boobooke –in ct.bin –out pt1.txt//解密非对称加密

Generate the private/public keyOpenssl genrsa –out file 1024

例如：Openssl genrsa –out priv.key 1024//用rsa算法生成私钥(priv.key)

Openssl rsa –in file –pubout

例如：Openssl rsa –in priv.key –pubout>pub.key//用私钥priv.key生成公钥,并重定向到pub.key这个文件里面

Encrypt the file with public keyOpenssl rsautl –in file –out file –inkey file –pubin –encrypt

例如：Openssl rsautl –in test.txt –out test.bin –inkey pub.key –pubin –encrypt//利用公钥文件（pub.key）对text.txt文件进行加密，生成加密后的文件text.bin

Decrypt the file the private key

Openssl rsautl –in file –out file –inkey file –decrypt

例如：Openssl rsautl –in text.bin –out text1.txt –inkey priv.key –decrypt//利用私钥priv.key对公钥加密的text.bin进行加密的文件进行解密，生成解密后的文件是text1.txt

Use openssl sign/verify functions(数字签名)

Generate the private/public key生成密钥对

Openssl genrsa –out file 1024O

penssl rsa –in file –puboutSign the file with the private key

Openssl rsautl –in file –out file –inkey file –sign

例如：Openssl rsatul –in test.txt –out test.sig –inkey priv.key –sign//利用私钥对test.txt进行加密也就是签名

Openssl rsautl –in file –out file –inkey file –pubin –verify

例如：Openssl rsautl –in test.sig –out test2.txt –inkey pub.key –pubin –verify //利用公钥对私钥加密后的文件（test.sig）进行解密或是认证

Hash functions（hash函数）……MD5 SHA1

作用：主要是验证文件的完整性，没有被别人篡改！

Generate the md5 hash resultOpenssl dgst –md5 file 或Md5sum file

例如：Openssl dgst –md5 openssl.tar.gz//生成MD5值

Md5sum openssl.tar.gzGenerate the sha1 hash resultOpenssl dgst –sha1file 或Sha1sum file

例如：Openssl –dgst –sha1 openssl.tar.gz//生成sha1值

Install apache

Configure the environmenttar –zxvf httpd-2.0.63.tar.gzcd httpd-2.0.63

./configure –prefix=/usr/local/apache –enable-ssl –with-ssl=/usr/local/opensslmakemake

installConfigure ssl in apache

openssl req -new -x509 -days 30 -keyout server.key -out server.crt -subj '/CN=Test Only Certifiecate'

或者

Openssl req –new –x509 –days 365 –sha1 –nodes –newkey rsa:1024 keyout server.key –out server.crt –subj ‘/O=Seccure/OU=Seccure Labs/CN=www.secdemo.com’Cpy the .key and .crt file to the proper directory //一般都是存放在apache的conf 目录下面，具体存放路径是在apache的配置文件中定义的Vi httpd.conf<IfModule mod_ssl.c>Include

conf/ssl.conf//ssl 的配置文件被包含在conf/ssl.conf</IfModule>Vi conf/ssl.confSSLCertificateKeyFile /usr/local/apache/conf/ssl.crt/server.key//server.key存放路径SSLCertificateFile /usr/local/apache/conf/ssl.crt/server.crt//server.crt 存放路径Apache2.2直接启动apache服务就可以启动SSLApache2.0启动ssl：apachectl startssl//端口号为443端口Vi conf/ssl.conf<Directory />SSLRequireSSL//此目录只允许使用https协议访问
