Interface CryptoService

All Known Implementing Classes:

AESCryptoService, NoCryptoService

public interface CryptoService

A self-contained cryptographic service. All on disk encryption and decryption will take place through this interface. Each implementation must implement a FileEncrypter for encryption and a FileDecrypter for decryption.

Since:

2.0.0

Method Details

init

void init(Map<String,String> conf)
   throws CryptoService.CryptoException

Initialize CryptoService. This should only be called once.

Throws:

CryptoService.CryptoException

getFileEncrypter

FileEncrypter getFileEncrypter(CryptoEnvironment environment)

Initialize the FileEncrypter for the environment and return. This will get called once per R-File or Write Ahead Log. FileEncrypter implementation is not expected be called by multiple threads.

getFileDecrypter

FileDecrypter getFileDecrypter(CryptoEnvironment environment)

Initialize the FileDecrypter for the environment and return. This will get called once per R-File or Write Ahead Log. FileDecrypter implementation must be thread safe.
