How to use Cassandra with TDE (Transparent Data En

问题:

I'm trying to figure out how to use Cassandra with TDE (Transparent Data Encryption) and in which DataStax edition TDE is supported.

I've been going through DataStax documentation and from what I see, TDE is supported only in DataStax Enterprise Edition. Is this correct?

Also, TDE is included on table/column level and is specified when creating new tables, not as some configuration?

Just want to confirm my assumptions.

Thanks in advance

回答1:

Your assumptions are correct.

Transparent Data Encryption is only supported in DataStax Enterprise (since version 3.2).

Transparent Data Encryption is specified when you create/alter a table

ALTER TABLE users WITH compression = { 
  'sstable_compression' : 'Encryptor',
  'cipher_algorithm' : 'AES/ECB/PKCS5Padding',
  'secret_key_strength' : 128,
  'chunk_length_kb' : 1 
  };

http://docs.datastax.com/en/datastax_enterprise/4.7/datastax_enterprise/sec/secTDEtblcrypt.html contains the latest documentation about Transparent Data Encryption in DSE 4.7
