#include <db_cxx.h>int DbEnv::set_encrypt(const char *passwd, u_int32_t flags);
int DbEnv::get_encrypt_flags(u_int32_t *flagsp);
Set the password used by the Berkeley DB library to perform encryption and decryption.
The DbEnv::set_encrypt method configures a database environment, not only operations performed using the specified DbEnv handle.
The DbEnv::set_encrypt method may not be called after the DbEnv::open method 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 either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
The DbEnv::set_encrypt method may fail and throw DbException, encapsulating one of the following non-zero errors, or return one of the following non-zero errors:
The DbEnv::get_encrypt_flags method returns the encryption flags.
The DbEnv::get_encrypt_flags method may be called at any time during the life of the application.
The DbEnv::get_encrypt_flags method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.
