4 +1 Create master key in master database (set master key)
5 +
6 +2 Create TDE certificate (encrypted by MK)
7 +
8 +3 Backup the Certificate and private key, By encryption with a password ( did not do it in this case due to storage blog problems)
9 +
10 +4 Choose DB to create the DEK ,Create database encryption key (DEK) with algorithm ( AES= 256) and encryption by certificate
11 +
12 +5 Set encryption on for the database

31 +The backup was unable to be done from smss to azure ( the MI does not support encrypted DBs to be backed up from smss to azure)
32 +
33 +We have unencrypted a database and backed it up from ssms to azure blob successfully
34 +
35 +
36 +Conclusion: Can be done with and unencrypted DB but not with an Encrypted one>
