- 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
