DB_ENV->set_encrypt(DB_ENV *dbenv, const char *passwd, u_int32_t flags);
Set the password used by the DB_ENV and DB methods to
perform encryption and decryption.
The flags value must be set to 0 or
the following value:
- Use the Rijndael/AES (also known as the Advanced Encryption Standard
and Federal Information Processing Standard (FIPS) 197) algorithm for
encryption or 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 interface may not be called after the DB_ENV->open
interface 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
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 a non-zero error for the following conditions:
- An invalid flag value or parameter was specified.
- Cryptography is not available in this Berkeley DB release.
The DB_ENV->set_encrypt method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
If a catastrophic error has occurred, the DB_ENV->set_encrypt method may fail and
in which case all subsequent Berkeley DB calls will fail in the same way.
