/**
 * A trust strategy that accepts self-signed certificates as trusted. Verification of all other
 * certificates is done by the trust manager configured in the SSL context.

Security Warning

* This acts like {@link TrustAllStrategy}, with the only restriction that the certificate chain * must have length 1. This means this trust strategy does not protect against man-in-the-middle * attacks. See the {@link TrustAllStrategy} for more information and more secure alternatives. * * @deprecated * For self-signed certificates prefer specifying a keystore containing the certificate when * calling the {@link org.apache.hc.core5.ssl.SSLContextBuilder} {@code loadTrustMaterial} * methods. * @since 4.1 */ @Deprecated @Contract(threading = ThreadingBehavior.STATELESS) public class TrustSelfSignedStrategy implements TrustStrategy { /** * Default instance of {@link TrustSelfSignedStrategy} */ public static final TrustSelfSignedStrategy INSTANCE = new TrustSelfSignedStrategy(); @Override public boolean isTrusted( final X509Certificate[] chain, final String authType) throws CertificateException { return chain.length == 1; } }
