Signs text with a certificate and returns the signature.
Applies to: SQL Server (SQL Server 2008 through current version).
The following example signs the text in @SensitiveData with certificate ABerglundCert07, having first decrypted the certificate with password "pGFD4bb925DGvbd2439587y". It then inserts the cleartext and the signature in table SignedData04.
DECLARE @SensitiveData nvarchar(max); SET @SensitiveData = N'Saddle Price Points are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29'; INSERT INTO [SignedData04] VALUES( N'data signed by certificate ''ABerglundCert07''', @SensitiveData, SignByCert( Cert_Id( 'ABerglundCert07' ), @SensitiveData, N'pGFD4bb925DGvbd2439587y' )); GO
