1. 生成证书 有效期 100年
2. 证书的名称 : pubKey
3.生成证书所需的盐值：7018 @z1
在java项目中使用rsa非对称加密 只需要生成 证书：pubKey.jks还有生成的公钥。一般不使用私钥。如果加密和解密只需要公钥和证书
开始操作
1.生成有效期100年的证书
keytool -genkeypair -alias pubKey -keyalg RSA -storetype PKCS12 -keysize 1024 -keypass 7018 @z1 -keystore pubKey.jks -storepass 7018 @z1 -validity 36500
2.查询公钥
keytool -list -rfc --keystore pubKey.jks | openssl x509 -inform pem -pubkey
