Encrypt

Description

Specifies that data should be encrypted before sending it over the network.

When to specify Encrypt

You must specify the Encrypt parameter before connecting to the database.

Applies to

SNC SQL Native Client for Microsoft SQL Server

MSOLEDBSQL Microsoft OLE DB Driver for SQL Server

Syntax

Encrypt=value

Parameter

Description

value

Specifies whether data should be encrypted. This parameter is used in conjunction with the TrustServerCertificate DBParm. Values are:

  • 0

    (Default) No encryption occurs.

  • 1

    If TrustServerCertificate is not set, encryption occurs only if there is a verifiable server certificate. If TrustServerCertificate is set, encryption always occurs, but may use a self-signed server certificate.


Default value

Encrypt=0

Usage

SQL Server 2005 always encrypts network packets associated with logging in to the server. If no certificate is provided on the server when it starts up, SQL Server generates a self-signed certificate that is used to encrypt login packets.

SQL Server Configuration Manager can be used to configure the SQL Native Client to request an encrypted connection using the Secure Sockets Layer (SSL), and to accept a self-signed certificate without validation. You can also request encryption by setting the Encrypt DBParm to 1, which sets the SQL Native Client connection string keyword Encrypt. To enable encryption to be used when a certificate has not been provided on the server, set both Encrypt and TrustServerCertificate. The value of TrustServerCertificate is ignored if Encrypt is not set.

Examples

To specify that PowerBuilder should encrypt data:

  • Database profile

    Select the Encrypt Data check box on the System page in the Database Profile Setup dialog box.

  • Application

    Type the following in code:

    SQLCA.DBParm="Encrypt=1"
