How to encrypt data in SQL Azure?

问题

My research does show me that we cannot use Transparent Data Encryption (TDE) in SQL Azure.

In this regard, are they any options for encrypting data in SQL Azure.

I do not want to have this Encrypt/Decrypt operations at application level.

Thanks,

There is an in depth explanation about which kinds of encryption are and are not supported by SQL Azure on TechNet:

SQL Azure does not currently support the standard data-encryption mechanisms that SQL Server supports. These include transparent data encryption, asymmetric keys, symmetric keys, and Transact-SQL functions such as ENCRYPTBYPASSPHRASE and DECRYPTBYPASSPHRASE, CREATE/ALTER/DROP DATABASE ENCRYPTION KEY or CREATE/ALTER/DROP MASTER KEY

TL;DR: Application level is probably your only choice right now
