#include <db.h> int DB_ENV->set_encrypt(DB_ENV *dbenv, const char *passwd, u_int32_t flags);
Set the password used by the Berkeley DB library to perform encryption and decryption.
The DB_ENV->set_encrypt()
method configures a database environment,
not only operations performed using the specified
DB_ENV handle.
The DB_ENV->set_encrypt()
method may not be called after the
DB_ENV->open()
method is called.
If the database environment already exists when
DB_ENV->open()
is called, the
information specified to DB_ENV->set_encrypt()
must be consistent
with the existing environment or an error will be returned.
The DB_ENV->set_encrypt()
method returns a non-zero error value on failure and 0 on success.
The DB_ENV->set_encrypt()
method may fail and return one of the following non-zero errors:
If the method was called after DB_ENV->open() was called; or if an invalid flag value or parameter was specified.
