About this task
WebSphere Application Server uses cryptography to protect sensitive data and to ensure confidentiality
and integrity of communications between WebSphere Application Server and other
components in the network. Cryptography is also used by Web services
security when certain security constraints are configured for the
Web Services application.
Attention: Fix packs that include updates to the Software Development
Kit (SDK) might overwrite unrestricted policy files. Back up unrestricted
policy files before you apply a fix pack and reapply these files after
the fix pack is applied.
Important: Your country of origin
might have restrictions on the import, possession, use, or re-export
to another country, of encryption software. Before downloading or
using the unrestricted policy files, you must check the laws of your
country, its regulations, and its policies concerning the import,
possession, use, and re-export of encryption software, to determine
if it is permitted.
