Prepare a test to check that existing user with RSA public keys are given a new EC public key after upgrade of data safe installation

[francis-pouatcha]

We want to:

1. run an older version of datasafe that uses RSA to write to inbox inbox,
2. run a new version that has ECDH as default, but can read data written to inbox using RSA.

Hello @max402, Please i wish to have more info and enlightenment on this ticket

In order to check if migrated data is available we have to first implement a data migration tool.
The tool should be able to:

• genarate EC keypair and add it to keystore for each user;
• convert data (decrypt with RSA private key, encrypt with EC public key);
• delete old RSA encrypted data, delete RSA keypair from keystore.

I would write tests for following scenarios:
1.

• user1 sends to inbox of user2 a file.
• user 2 has EC public key in public profile.
• user2 can read their Inbox

• user1 sends to inbox of user2 a file. User2 public profile has RSA keypair
• user2 logins, EC keypair created, public profile key replaced to EC.
• user1 sends another file. The file encrypted using EC public key.
• user2 can read both files form inbox.
