Encryption Key generated from the answers to the Encryption Questions you’ve for each one of your Contacts.
This key is generated in real time and discarded immediately after being used - in two moments:
- When you save an encrypted message to a Contact, answering the questions you have set for it;
- When that Contact accesses your message and responds correctly to the questions you have been asked. The answers must be exactly the same as the answers you gave when encrypting the message.
The algorithm used to create this key and encryption is 256 bit AES.
