To get SymmetricKey object properties, users can be a member of the public fixed server role.

To set SymmetricKey object properties, users must have ALTER permission on the symmetric key.

To create a symmetric key, users must have ALTER ANY SYMMETRIC KEY permissions on the parent database.

To drop a symmetric key, users must have CONTROL permissions on the symmetric key.

To open the symmetric key, users must know the password used to encrypt the symmetric key. CONTROL permission is also required on the certificate or other symmetric key when used to open the specified symmetric key.
