生成私钥+证书:
keytool -genkey -alias client -keysize 2048 -validity 3650 -keyalg RSA -dname "CN=localhost" -keypass $client_passwd -storepass $client_passwd -keystore ClientCert.jks
生成文件文件ClientCert.jks。工具
导出证书:code
~/tmp/cert# keytool -export -alias client -keystore ClientCert.jks -storepass $client_passwd -file ClientCert.crt Certificate stored in file <ClientCert.crt> ~/tmp/cert# ll total 8 -rw-r--r-- 1 root root 715 Jun 14 20:24 ClientCert.crt -rw-r--r-- 1 root root 2066 Jun 14 20:21 ClientCert.jks
keytool工具不支持导出私钥。orm
生成公钥私钥:server
~/tmp/cert# openssl genrsa -des3 -out private.pem 1024 Generating RSA private key, 1024 bit long modulus .............................++++++ ...........++++++ e is 65537 (0x10001) Enter pass phrase for private.pem: Verifying - Enter pass phrase for private.pem: ~/tmp/cert# ll total 4 -rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem
建立证书请求:ssl
~/tmp/cert# openssl req -subj "/C=CN/ST=BJ/L=BJ/O=HW/OU=HW/CN=CL/emailAddress=xxx@xxx.com" -new -out cert.csr -key private.pem Enter pass phrase for private.pem: ~/tmp/cert# ll total 8 -rw-r--r-- 1 root root 664 Jun 14 20:43 cert.csr -rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem
自签发证书:openssl
~/tmp/cert# openssl x509 -req -in cert.csr -out public.crt -outform pem -signkey private.pem -days 3650 Signature ok subject=/C=CN/ST=BJ/L=BJ/O=HW/OU=HW/CN=CL/emailAddress=xxx@xxx.com Getting Private key Enter pass phrase for private.pem: ~/tmp/cert# ll total 12 -rw-r--r-- 1 root root 664 Jun 14 20:43 cert.csr -rw-r--r-- 1 root root 963 Jun 14 20:27 private.pem -rw-r--r-- 1 root root 871 Jun 14 20:44 public.crt
keytool和openssl生成的证书相互之间没法识别,keytool生成的为jsk文件,openssl默认生成的为PEM格式文件。须要先转换成pkcs12格式,而后再使用对方的命令转换成须要的格式。it
