SAS/SHARE User's Guide

Data Encryption

Encryption services protect data that is sent between hosts across a network. Encryption services use a reversible algorithm to convert plain-text data into an unintelligible form, thus protecting data from being used by unauthorized parties.

For the OS/390, OpenVMS, OS/2, and UNIX platforms, the purchase of a license for SAS/SECURE is necessary. SAS/SECURE provides access to the encryption services of the RSA BSAFE Crypto-C Toolkit.

[IMAGE] In Version 8, SAS/SECURE introduces support for the RSA BSAFE Crypto-J Toolkit for Java clients of the SAS server.

SAS system options for data encryption for the RSA BSAFE Crypto-C Toolkit and the Microsoft CryptoAPI (for Windows) are:

NETENCRYPT: specifies the requirement to operate in encryption mode; for example, both the client and the server sessions must be operating in encryption mode.
NETENCRYPTALGORITHM: specifies one or more encryption algorithms to use in a SAS/SHARE client/server session.
NETENCRYPTKEYLEN: specifies the key length - 40-bit or 128-bit - to be used by the encryption algorithm.
NETMAC: controls the use of Message Authentication Codes (MACs) on network communications. A MAC is the equivalent of a checksum that is used to ensure that the original message has not been modified.

Other documentation explains options that are applicable to RSA BSAFE Crypto-J Toolkit Java clients.
