Data Encryption
You can encrypt your data in two environments: onsite or in Windows Azure using a service. SQL Azure,
as previously mentioned, doesn't support encryption at this time (although hashing is supported). If you
need to encrypt Social Security numbers or phone numbers, you should consider where encryption
makes sense.
Generally speaking, unless your application runs in a public environment where your private keys
can be at risk, you should consider encrypting onsite before the data goes over the Internet. But if you
need a way to decrypt in Windows Azure, or you need to encrypt and decrypt data across consumers that
don't share keys, you probably need to encrypt your data in Windows Azure before storing it in SQL
Azure.
