一、安装环境
可从Oracle官方下载jre安装包:https://www.oracle.com/java/technologies/downloads/#java8
将jre命令添加到临时环境变量中
二、生成证书
keytool -genkey -alias testalias -keyalg RSA -keysize 2048 -validity 36500 -keystore test.keystore
testalias是证书别名,可修改为自己想设置的字符,建议使用英文字母和数字
test.keystore是证书文件名称,可修改为自己想设置的文件名称,也可以指定完整文件路径
36500是证书的有效期,表示100年有效期,单位天,建议时间设置长一点,避免证书过期
复制代码
Enter keystore password: //输入证书文件密码,输入完成回车
Re-enter new password: //再次输入证书文件密码,输入完成回车
What is your first and last name?
[Unknown]: //输入名字和姓氏,输入完成回车
What is the name of your organizational unit?
[Unknown]: //输入组织单位名称,输入完成回车
What is the name of your organization?
[Unknown]: //输入组织名称,输入完成回车
What is the name of your City or Locality?
[Unknown]: //输入城市或区域名称,输入完成回车
What is the name of your State or Province?
[Unknown]: //输入省/市/自治区名称,输入完成回车
What is the two-letter country code for this unit?
[Unknown]: //输入国家/地区代号(两个字母),中国为CN,输入完成回车
Is CN=XX, OU=XX, O=XX, L=XX, ST=XX, C=XX correct?
[no]: //确认上面输入的内容是否正确,输入y,回车
Enter key password for
(RETURN if same as keystore password): //确认证书密码与证书文件密码一样(HBuilder|HBuilderX要求这两个密码一致),直接回车就可以
三、查看证书
keytool -list -v -keystore test.keystore
Enter keystore password: //输入密码,回车
会输出以下格式信息
Keystore type: PKCS12
Keystore provider: SUN

五、查看公钥
1、从keystore中获取MD5证书
keytool -list -v -keystore gamekeyold.keystore
2、导出公钥文件
keytool -export -alias "别名" -file gamekeyold.cer -keystore gamekeyold.keystore
3、转换成pem证书
openssl x509 -inform der -in gamekeyold.cer -out gamekeyold.pem
4、查看公钥
keytool -list -rfc --keystore gamekeyold.keystore | openssl x509 -inform pem -pubkey
六、查看私钥
1、keystore转换为JKS
keytool -importkeystore -srckeystore gamekeyold.keystore -destkeystore gamekeyold.jks -deststoretype pkcs12
2、JKS转换为PKCS12格式
keytool -importkeystore -srckeystore gamekeyold.jks -destkeystore gamekeyold.pkcs -srcstoretype JKS -deststoretype PKCS12
//或者:
keytool -importkeystore -srckeystore gamekeyold.jks -destkeystore gamekeyold.p12 -srcstoretype JKS -deststoretype PKCS12
3、PKCS12格式转为pem
openssl pkcs12 -in gamekeyold.p12 -out gamekeyoldprivate.pem
4、生成私钥pem文件
openssl pkcs12 -in gamekeyold.p12 -nodes -nocerts -out gamekeyold_private_key.pem
