DbEnv.set_encrypt

 APIRef 

import com.sleepycat.db.*;


public void set_encrypt(String passwd, int flags)
    throws DbException;

Description

Set the password used by the DbEnv and Db methods to perform encryption and decryption.

The flags value must be set to 0 or the following value:

Db.DB_ENCRYPT_AES
Use the Rijndael/AES (also known as the Advanced Encryption Standard and Federal Information Processing Standard (FIPS) 197) algorithm for encryption or decryption.

The DbEnv.set_encrypt method configures a database environment, not only operations performed using the specified DbEnv handle.

The DbEnv.set_encrypt interface may not be called after the DbEnv.open interface is called. If the database environment already exists when DbEnv.open is called, the information specified to DbEnv.set_encrypt must be consistent with the existing environment or an error will be returned.

The DbEnv.set_encrypt method throws an exception that encapsulates a non-zero error value on failure.

Errors

The DbEnv.set_encrypt method may fail and throw an exception encapsulating a non-zero error for the following conditions:

EINVAL
An invalid flag value or parameter was specified.

Called after DbEnv.open was called.

EOPNOTSUPP
Cryptography is not available in this Berkeley DB release.

The DbEnv.set_encrypt method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv.set_encrypt method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
