@Private
public final class X509Util
extends Object

Utility code for X509 handling Default cipher suites: Performance testing done by Facebook engineers shows that on Intel x86_64 machines, Java9 performs better with GCM and Java8 performs better with CBC, so these seem like reasonable defaults.

HBASE_SERVER_NETTY_TLS_WRAP_SIZE

public static final String HBASE_SERVER_NETTY_TLS_WRAP_SIZE

Set the SSL wrapSize for netty. This is only a maximum wrap size. Buffers smaller than this will not be consolidated, but buffers larger than this will be split into multiple wrap buffers. The netty default of 16k is not great for hbase which tends to return larger payloads than that, meaning most responses end up getting chunked up. This leads to more memory contention in netty's PoolArena. See https://github.com/netty/netty/pull/13551

Method Details

createSslContextForClient

public static org.apache.hbase.thirdparty.io.netty.handler.ssl.SslContext createSslContextForClient(org.apache.hadoop.conf.Configuration config)
                                                                                             throws X509Exception,
IOException

Throws:

X509Exception

IOException

configureOpenSslIfAvailable

private static boolean configureOpenSslIfAvailable(org.apache.hbase.thirdparty.io.netty.handler.ssl.SslContextBuilder sslContextBuilder,
 org.apache.hadoop.conf.Configuration conf)

Adds SslProvider.OPENSSL if OpenSsl is available and enabled. In order to make it available, one must ensure that a properly shaded netty-tcnative is on the classpath. Properly shaded means relocated to be prefixed with "org.apache.hbase.thirdparty" like the rest of the netty classes. We make available org.apache.hbase:hbase-openssl as a convenience module which one can use to pull in a shaded netty-tcnative statically linked against boringssl.

createSslContextForServer

public static org.apache.hbase.thirdparty.io.netty.handler.ssl.SslContext createSslContextForServer(org.apache.hadoop.conf.Configuration config)
                                                                                             throws X509Exception,
IOException

Throws:

X509Exception

IOException

createKeyManager

static X509KeyManager createKeyManager(String keyStoreLocation,
 char[] keyStorePassword,
 String keyStoreType)
                                throws KeyManagerException

Creates a key manager by loading the key store from the given file of the given type, optionally decrypting it using the given password.

Parameters:

keyStoreLocation - the location of the key store file.

keyStorePassword - optional password to decrypt the key store. If empty, assumes the key store is not encrypted.

keyStoreType - must be JKS, PEM, PKCS12, BCFKS or null. If null, attempts to autodetect the key store type from the file extension (e.g. .jks / .pem).

Returns:

the key manager.

Throws:

KeyManagerException - if something goes wrong.

createTrustManager

static X509TrustManager createTrustManager(String trustStoreLocation,
 char[] trustStorePassword,
 String trustStoreType,
 boolean crlEnabled,
 boolean ocspEnabled,
 boolean verifyHostName,
 boolean allowReverseDnsLookup)
                                    throws TrustManagerException

Creates a trust manager by loading the trust store from the given file of the given type, optionally decrypting it using the given password.

Parameters:

trustStoreLocation - the location of the trust store file.

trustStorePassword - optional password to decrypt the trust store (only applies to JKS trust stores). If empty, assumes the trust store is not encrypted.

trustStoreType - must be JKS, PEM, PKCS12, BCFKS or null. If null, attempts to autodetect the trust store type from the file extension (e.g. .jks / .pem).

crlEnabled - enable CRL (certificate revocation list) checks.

ocspEnabled - enable OCSP (online certificate status protocol) checks.

verifyHostName - if true, ssl peer hostname must match name in certificate

allowReverseDnsLookup - if true, allow falling back to reverse dns lookup in verifying hostname

Returns:

the trust manager.

Throws:

TrustManagerException - if something goes wrong.

enableCertFileReloading

public static void enableCertFileReloading(org.apache.hadoop.conf.Configuration config,

 AtomicReference<FileChangeWatcher> trustStoreWatcher,
 Runnable resetContext)
                                    throws IOException

Enable certificate file reloading by creating FileWatchers for keystore and truststore. AtomicReferences will be set with the new instances. resetContext - if not null - will be called when the file has been modified.

Parameters:

keystoreWatcher - Reference to keystoreFileWatcher.

trustStoreWatcher - Reference to truststoreFileWatcher.

resetContext - Callback for file changes.

Throws:

IOException

newFileChangeWatcher

private static FileChangeWatcher newFileChangeWatcher(org.apache.hadoop.conf.Configuration config,

Throws:

IOException

handleWatchEvent

private static void handleWatchEvent(Path filePath,
