Worth noting: The DB migration will happen on the first successful login. The new DB version will have a different name to be able to distinguish between different DB versions.Versions naming mirrors sqlcipher major version (naming conventions used by sqlcipher), meaning that we're migrating from V3 to V4 DB (even if we're not fully aligned with V4 standards). The DB is not migrated to the v4 standard `SHA512` due to performance reasons. Our custom `SHA1` implementation is fully optimised for perfomance. * perf(sqlCipher): Fixing failing tests Update the new DB file format in Delete account, Change password and Decrypt database flows * perf(SQLCipher): Increase page size - send events to notify when the DB re-encryption starts/ends
