getEncryptSembastCodecAES function
Create a codec to use to open a database with encrypted stored data.
Hash (sha256 - because someone told me they didn't like md5) of the password is used (but never stored) as a key to encrypt the data using the AES-256 algorithm with a random (8 bytes) initial value
This is just used as a demonstration and should not be considered as a reference since its implementation (and storage format) might change.
No performance metrics has been made to check whether this is a viable solution for big databases.
The usage is then
Initialize the encryption codec with a user password
var codec = getEncryptSembastCodec(password: 'your_user_password');
Open the database with the codec
Database db = await factory.openDatabase(dbPath, codec: codec);
...your database is ready to use
Implementation
SembastCodec getEncryptSembastCodecAES({required String password}) =>
SembastCodec(
signature: _encryptCodecSignature,
codec: _EncryptCodec(_generateEncryptPassword(password)));
