fdcd56401a Added specific test cases for EncryptedBlockStore 2015-05-06 00:37:57 +02:00
Sebastian Messmer
0042ae1cef - Run test cases for EncryptedBlockStore with different ciphers 
- Implement FakeAuthenticatedCipher for use with specific EncryptedBlockStoreTest
- Write skeleton for specific EncryptedBlockStoreTest
- Fix behavior of AES256_CFB when called with too small input
- Add testcase that all ciphers (also non-authenticating ones) have to handle too small input correctly

417a701636 - BlockStore::create() gets the data of the new block as a parameter 
- Fixed numBlocks() in OnDiskBlockStore, FakeBlockStore, CachingBlockStore, ...
