Method Details

init

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

Description copied from interface: CryptoService

Initialize CryptoService. This should only be called once.

Specified by:

init in interface CryptoService

Throws:

CryptoService.CryptoException

getFileEncrypter

public FileEncrypter getFileEncrypter(CryptoEnvironment environment)

Description copied from interface: CryptoService

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

Specified by:

getFileEncrypter in interface CryptoService

getFileDecrypter

public FileDecrypter getFileDecrypter(CryptoEnvironment environment)

Description copied from interface: CryptoService

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.

Specified by:

getFileDecrypter in interface CryptoService

generateKey
