// 1. Create with both inputString and prepareString.
// 1.1 Check opening both of these documents with both strings.
// 2. Try encrypt document with invalid input string.
// 3. Try open encrypted document with password that contains unassigned code points and ensure error is due to wrong password instead of the invalid input string.
