[LDAP SSL]인증서 생성

1.키툴로 인증서 생성하기

keytool -genkey -alias ldap

2.키저장소 엔트리 확인

keytool -v -list

3.키 저장소로부터 인증서 추출

keytool -export -alias ldap -file ldap.cer

 

4.인증서 보기 예제

import java.io.FileInputStream; import java.security.cert.Certificate; import java.security.cert.CertificateFactory;   public class PrintCertInfo {          public static void main(String[] args) throws Exception {              CertificateFactory certFactory = CertificateFactory.getInstance("X.509");              FileInputStream fis = new FileInputStream("c:\\ldap.cer");              Certificate cert = certFactory.generateCertificate(fis);              fis.close();              System.out.println(cert);        } } [출처] [암호화] 전자 인증서|작성자 버들

 

 

5.키저장소로부터 인증서를 읽어 들이는 예제

import java.io.File; import java.io.FileInputStream; import java.security.KeyStore; import java.security.cert.Certificate;   public class PrintCertFromKeyStore {          public static void main(String[] args) throws Exception {              String userHome = System.getProperty("user.home");              String keyStoreFileName = userHome + File.separator + ".keystore";                           // keystore에 대한 패스워드와 엔트리에 대한 alias 지정              char[] password = "password".toCharArray();              String alias = "test";                           FileInputStream fis = new FileInputStream(keyStoreFileName);              KeyStore keyStore = KeyStore.getInstance("JKS");              keyStore.load(fis, password);                           Certificate cert = keyStore.getCertificate(alias);              System.out.println(cert);        } }
