Configuring Encryption and Compression

When you configure connections to extract or load data with PowerExchange, you can set connection attributes to encrypt or compress data during the PowerCenter session.

Set the

Compression

Encryption Type

, and

Encryption Level

connection attributes to compress data or to encrypt data. These attributes override the values in the COMPRESS, ENCRYPT, and ENCRYPTLEVEL statements, if defined, in the DBMOVER configuration file on the Integration Service machine. To enable compression or encryption for a PowerCenter session, be sure to select the appropriate connection attributes.

Informatica recommends that you use Secure Sockets Layer (SSL) authentication instead of configuring the

Encrypt Level

and

Encryption Type

connection attributes or the ENCRYPT and ENCRYPTLEVEL statements in the DBMOVER configuration file. SSL authentication provides stricter security and is used by several Informatica products. For more information about implementing SSL authentication, see the "Secure Sockets Layer Support" chapter in the

PowerExchange Reference Manual

For more information about implementing SSL authentication in a PowerExchange network, see the

PowerExchange Reference Manual

The following table describes the connection attributes for compression and encryption:

Connection Attribute	Required	Description
Compression	No	Select this attribute to compress source data during the PowerCenter session.
Encryption Level	No	If you select AES for Encryption Type , enter one of the following values to indicate the encryption level: 1 . Use a 128-bit encryption key. 2 . Use a 192-bit encryption key. 3 . Use a 256-bit encryption key. Default is 1 . If you select None for Encryption Type , PowerExchange ignores the Encryption Level value.
Encryption Type	Yes	Select one of the following values for the encryption type: None AES Default is None . The values of DES and RC2 are deprecated. PowerExchange converts a value of DES and RC2 to AES .
