CryptoService (Apache Accumulo Core 2.1.0 API)

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

- Method Detail
  - 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 must be thread safe.
  - 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.
