Java 自動安裝校驗TLS/SSL證書
更新時間：2020年10月21日 08:50:47 作者：默默的點滴
這篇文章主要介紹了Java 自動安裝校驗TLS/SSL證書的示例，幫助大家更好的理解和使用Java，感興趣的朋友可以了解下
前言
最近實現(xiàn)Socks5 proxy與HTTP proxy中遇到了SSLSocket隧道的問題，當然，最終問題經(jīng)過自動證書校驗安裝管理器實現(xiàn)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(xiàn)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(xiàn)TLS/SSL證書的自動安裝校驗，主要經(jīng)過ssl/tls握手，密鑰交換，證書校驗機制實現(xiàn)。我們這里模擬瀏覽器，實現(xiàn)自動校驗和證書的檢測。
主要實現(xiàn)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(xiàn)證書的自動存儲，自動安裝，加載
3.實現(xiàn)普通Socket自動升級為SSLSocket
一.實現(xiàn)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javaBean
package 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;
}
@Override
public 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;
}
@Override
public 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(xiàn)核心部分，證書管理器
二.實現(xiàn)核心代碼
package com.ssl.rx.http;
public class SSLX509CertificateManager {
private static final Logger logger = Logger.getLogger("SSLX509CertificateManager");
private static final char[] HEXDIGITS = "0123456789abcdef".toCharArray();
private static Pattern cnPattern = Pattern.compile("(?i)(cn=)([^,]*)");
private static Map<KeyStoreOptions, KeyStore> stores = new HashMap<KeyStoreOptions, KeyStore>();
private static String toHexString(byte[] bytes) {
StringBuilder sb = new StringBuilder(bytes.length * 3);
for (int b : bytes) {
b &= 0xff;
sb.append(HEXDIGITS[b >> 4]);
sb.append(HEXDIGITS[b & 15]);
sb.append(' ');
}
return sb.toString();
}

三.測試代碼

SSLSocket imququSocket = SSLX509CertificateManager.createTrustCASocket("imququ.com", 443);
} catch (Exception e) {
e.printStackTrace();
}
}
}
