在过去的几天里,我一直在努力尝试在 Android 中实现 OCSP 验证。
到目前为止,iOS 中的实现很容易,但对于 Android,我遇到的每一条信息都不起作用。我一直在使用我客户的 API 端点和 这个网站来运行证书吊销测试,到目前为止,我还没有幸运地在我的 Android 应用程序中检测到吊销的证书。我正在使用 OKHTTPClient。这是我验证证书吊销的方法
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
assert (chain != null);
if (chain == null) {
throw new IllegalArgumentException(
"checkServerTrusted: X509Certificate array is null");
}
assert (chain.length > 0);
if (!(chain.length > 0)) {
throw new IllegalArgumentException(
"checkServerTrusted: X509Certificate is empty");
}
if (VERIFY_AUTHTYPE) {
assert (null != authType && authType.equalsIgnoreCase(AUTH_TYPE));
if (!(null != authType && authType.equalsIgnoreCase(AUTH_TYPE))) {
throw new CertificateException(
"checkServerTrusted: AuthType is not " + AUTH_TYPE);
}
}
if(chain[0]!=null){
try {
X509Certificate issuerCert = chain[1];
X509Certificate c1 = chain[0];
TrustAnchor anchor = new TrustAnchor(issuerCert, null);
Set anchors = Collections.singleton(anchor);
CertificateFactory cf = CertificateFactory.getInstance("X.509");
List list = Arrays.asList(new Certificate[]{c1});
CertPath path = cf.generateCertPath(list);
PKIXParameters params = new PKIXParameters(anchors);
// Activate certificate revocation checking
params.setRevocationEnabled(false);
// Activate OCSP
Security.setProperty("ocsp.enable", "true");
// Ensure that the ocsp.responderURL property is not set.
if (Security.getProperty("ocsp.responderURL") != null) {
throw new
Exception("The ocsp.responderURL property must not be set");
}
CertPathValidator validator = CertPathValidator.getInstance("PKIX");
PKIXCertPathValidatorResult result = (PKIXCertPathValidatorResult) validator
.validate(path, params);
System.out.println("VALID");
} catch (Exception e) {
System.out.println("EXCEPTION " + e.getMessage());
e.printStackTrace();
}
