Below are the steps to know if the FIPS algorithm is enabled or disabled on the Windows machine where the issue occurs:
  • Open Local Security Policy editor (search for it in start menu)
  • Select *Local Policies\Security Options to the left
  • See Security setting for policy “System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing” is set to "Enabled"

Issue/Introduction

This article gives information about what all Spotfire versions are FIPS compliant using OAuth2 web authentication and possible workaround for other versions.

Resolution

This is a known issue where OAuth2 web authentication in TIBCO Spotfire is not FIPS compliant for versions 10.2 and lower. Starting with version 10.3, Spotfire will be FIPS compliant and Web/OAuth2 authentication can be used on FIPS enabled Windows machines.

The issue is also fixed in the following versions:
  • TIBCO Spotfire 7.11 HF-018 and higher 
  • TIBCO Spotfire 10.2 HF-002 and higher
  • TIBCO Spotfire 10.3 and higher
See the list of client hotfixes for more details.

To resolve the issue:
  • Upgrade to any of the versions mentioned above via upgrade or hotfix if applicable to your version: 7.11 HF-018 and higher, 10.2 HF-002 and higher, or 10.3 and higher.
or:
  • For other versions, disable the FIPS algorithm by setting the “System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing” registry entry described above to "Disabled"
