Method Detail

testKeyProvider

public static void testKeyProvider(org.apache.hadoop.conf.Configuration conf)
                            throws IOException

Check that the configured key provider can be loaded and initialized, or throw an exception. nn

Throws:

IOException

testCipherProvider

public static void testCipherProvider(org.apache.hadoop.conf.Configuration conf)
                               throws IOException

Check that the configured cipher provider can be loaded and initialized, or throw an exception. nn

Throws:

IOException

testEncryption

public static void testEncryption(org.apache.hadoop.conf.Configuration conf,
                                  String cipher,
                                  byte[] key)
                           throws IOException

Check that the specified cipher can be loaded and initialized, or throw an exception. Verifies key and cipher provider configuration as a prerequisite for cipher verification. Also verifies if encryption is enabled globally.

Parameters:

conf - HBase configuration

cipher - chiper algorith to use for the column family

key - encryption key

Throws:

IOException - in case of encryption configuration error
