前言

最近實現Socks5 proxy與HTTP proxy中遇到了SSLSocket隧道的問題，當然，最終問題經過自動證書校驗安裝管理器實現了證書的管理，也解決了SSLSocket，但是目前的問題是瀏覽器對Socks5和HTTP proxy還有很多不足，目前實現的兩個代理工具只能在程序中使用。當然，我們今天的主要話題如下：

Java 實現TLS/SSL證書的自動安裝校驗，主要經過ssl/tls握手，密鑰交換，證書校驗機制實現。我們這里模擬瀏覽器，實現自動校驗和證書的檢測。

主要實現如下功能：

1.自動檢測，校驗根證書，校驗過期時間，校驗簽名的證書是否有效，校驗證書和域名是否匹配

2.實現證書的自動存儲，自動安裝，加載

3.實現普通Socket自動升級為SSLSocket

一.實現配置類

首先，我們先添加2個配置類

package com.ssl.rx.http;import java.security.KeyStore;public class ConnectionConfiguration {/** 證書文件路徑 */private String truststorePath;/** 證書類型 */private String truststoreType;/** 證書文件密碼 */private String truststorePassword;/** 是否驗證證書鏈的簽名有效性 */private boolean verifyChainEnabled = true;/** 是否校驗根證書，注意，自簽名證書沒有根證書 */private boolean verifyRootCAEnabled = true;/** 是否允許通過自簽名證書 */private boolean selfSignedCertificateEnabled = false;/** 是否檢查證書的有效期 */private boolean expiredCertificatesCheckEnabled = true;/** 檢查域名的匹配情況 */private boolean notMatchingDomainCheckEnabled = true;private String server;private int port;public ConnectionConfiguration() {truststorePassword = 'WlZSak5GcFVUbTlsVjJSNg==';truststorePath = 'socket_tls_clientTrust.cert';truststoreType = 'jks';}public int getPort() {return port;}public void setPort(int port) {this.port = port;}public String getServer() {return server;}public void setServer(String server) {this.server = server;}public boolean isExpiredCertificatesCheckEnabled() {return expiredCertificatesCheckEnabled;}public void setSelfSignedCertificateEnabled(boolean selfSignedCertificateEnabled) {this.selfSignedCertificateEnabled = selfSignedCertificateEnabled;}public void setExpiredCertificatesCheckEnabled(boolean expiredCertificatesCheckEnabled) {this.expiredCertificatesCheckEnabled = expiredCertificatesCheckEnabled;}public boolean isSelfSignedCertificateEnabled() {return selfSignedCertificateEnabled;}public boolean isNotMatchingDomainCheckEnabled() {return notMatchingDomainCheckEnabled;}public boolean isVerifyRootCAEnabled() {return verifyRootCAEnabled;}public void setVerifyRootCAEnabled(boolean verifyRootCAEnabled) {this.verifyRootCAEnabled = verifyRootCAEnabled;}public void setVerifyChainEnabled(boolean verifyChainEnabled) {this.verifyChainEnabled = verifyChainEnabled;}public boolean isVerifyChainEnabled() {return verifyChainEnabled;}public String getTruststoreType() {return truststoreType;}public void setTruststoreType(String truststoreType) {this.truststoreType = truststoreType;}public String getTruststorePassword() {return truststorePassword;}public void setTruststorePassword(String truststorePassword) {this.truststorePassword = truststorePassword;}public String getTruststorePath() {return truststorePath;}public void setTruststorePath(String truststorePath) {this.truststorePath = truststorePath;}public void setNotMatchingDomainCheckEnabled(boolean notMatchingDomainCheckEnabled) {this.notMatchingDomainCheckEnabled = notMatchingDomainCheckEnabled;}}然后增加一個用于存儲keystore的javaBeanpackage com.ssl.rx.http;public class KeyStoreOptions {private final String type;private final String path;private final String password;public KeyStoreOptions(String type, String path, String password) {super();this.type = type;this.path = path;this.password = password;}public String getType() {return type;}public String getPath() {return path;}public String getPassword() {return password;}@Overridepublic int hashCode() {final int prime = 31;int result = 1;result = prime * result + ((password == null) ? 0 : password.hashCode());result = prime * result + ((path == null) ? 0 : path.hashCode());result = prime * result + ((type == null) ? 0 : type.hashCode());return result;}@Overridepublic boolean equals(Object obj) {if (this == obj)return true;if (obj == null)return false;if (getClass() != obj.getClass())return false;KeyStoreOptions other = (KeyStoreOptions) obj;if (password == null) {if (other.password != null)return false;} else if (!password.equals(other.password))return false;if (path == null) {if (other.path != null)return false;} else if (!path.equals(other.path))return false;if (type == null) {if (other.type != null)return false;} else if (!type.equals(other.type))return false;return true;}}

最后，我們來實現核心部分，證書管理器

二.實現核心代碼

三.測試代碼

public class TestX509CertManager { public static void main(String[] args) {try {SSLSocket baiduSocket = SSLX509CertificateManager.createTrustCASocket('www.baidu.com', 443);SSLSocket taobaoSocket = SSLX509CertificateManager.createTrustCASocket('www.taobao.com', 443);SSLSocket imququSocket = SSLX509CertificateManager.createTrustCASocket('imququ.com', 443);} catch (Exception e) {e.printStackTrace();}}}
