SSLHandShakeException 没有合适的协议

2022-08-31 16:47:43

我最近将SSL添加到我的网站,可以通过https访问它。现在,当我的java应用程序尝试向我的网站发出请求并使用缓冲读取器从中读取时,它会生成此堆栈跟踪

我没有使用自签名证书,证书来自Namecheap,他使用COMODO SSL作为CA来签署我的证书。im using java 8

javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
at sun.security.ssl.Handshaker.activate(Handshaker.java:503)
at sun.security.ssl.SSLSocketImpl.kickstartHandshake(SSLSocketImpl.java:1482)
at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1351)
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1403)
at sun.security.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1387)
at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:559)

我的代码非常基本,只是尝试使用缓冲阅读器读取我网站上的页面

 private void populateDataList() {
    try {
        URL url = new URL("https://myURL.com/Data/Data.txt");
        URLConnection con = url.openConnection();
        con.setRequestProperty("Connection", "close");
        con.setDoInput(true);
        con.setUseCaches(false);

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String line;
        int i = 0;
        while((line = in.readLine()) != null) {
            this.url.add(i, line);
            i++;
        }
    }   catch (Exception e) {
        e.printStackTrace();
    }

}

Ive尝试将我的SSL证书添加到JVM的密钥库,Ive甚至还尝试用此代码接受每个证书(这违背了我知道的SSL的目的)。

 private void trustCertificate() {
    TrustManager[] trustAllCerts = new TrustManager[] {
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
                public void checkClientTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
                public void checkServerTrusted(
                        java.security.cert.X509Certificate[] certs, String authType) {
                }
            }
    };
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (GeneralSecurityException e) {
    }
    try {
        URL url = new URL("https://myURL.com/index.php");
        URLConnection con = url.openConnection();
        BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String line;
        while((line = br.readLine()) != null) {
            System.out.println(line);
        }

    } catch (Exception e) {

    }
}

我感到困惑,任何帮助将不胜感激!


答案 1

在:$JRE/lib/security/java.security

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, RC4, DES, MD5withRSA, DH keySize < 1024, \
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

这行已启用,在我注释掉此行后,一切正常。显然,在启用此行之后/jre1.8.0_181。

我的 Java 版本是“1.8.0_201”。


答案 2

我在Ubuntu 18.04上的Java8更新1.8.0.229中也遇到了这个问题。

我更改了以下部分:

# Example:
#   jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048
#jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \
#    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
#    include jdk.disabled.namedCurves

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \
    DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \
    include jdk.disabled.namedCurves

我从文件内部的列表中删除和TLSv1TLSv1.1jdk.tls.disabledAlgorithms

/etc/java-8-openjdk/security/java.security
