* chore(upgradeSQLCipher): Upgrading SQLCipher to version 5.4.5 Changes: ### github.com/mutecomm/go-sqlcipher 1. The improved crypto argorighms from go-sqlcipher v3 are merged in v4 Tags: v4.4.2-status.1 - merge `burn_stack` improvement v4.4.2-status.2 - merge `SHA1` improvement v4.4.2-status.4- merge 'AES' improvement 2. Fixed `go-sqlcipher` to support v3 database in compatibility mode (`sqlcipher` already supports this) (Tag: v4.4.2-status.3) 3. Upgrade `sqlcipher` to v5.4.5 (Tag: v4.5.4-status.1) ### github.com/status-im/migrate/v4 1. Upgrade `go-sqlcipher` version in `github.com/status-im/migrate/v4` ### status-go 1. Upgrade `go-sqlcipher` and `migrate` modules in status-go 2. Configure the DB connections to open the DB in v3 compatibility mode * chore(upgradeSQLCipher): Use sqlcipher v3 configuration to encrypt a plain text database * chore(upgradeSQLCipher): Scanning NULL BLOB value should return nil Fixing failing tests: TestSyncDeviceSuite/TestPairingSyncDeviceClientAsReceiver; TestSyncDeviceSuite/TestPairingSyncDeviceClientAsSender Considering the following configuration: 1. Table with BLOB column has 1 NULL value 2. Query the value 3. Rows.Scan(&dest sql.NullString) Expected: dest.Valid == false; dest.String == nil Actual: dest.Valid == true; dest.String == "" * chore: Bump go-sqlcipher version to include NULL BLOB fix
