SharePoint 2016 Configuration Failed: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

Question

Hi,I Prepared new SharePoint 2016 Test Server and when i run Configuration wizard in Updating SharePoint step it throws the following error:

This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.
anyone has idea how to fix this issue and for SharePoint Server is below Security policy required to be enabled or disable? i checked in server it was Enable.
security policy 'System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing'

Answer 1

FIPS must be disabled. SharePoint uses MD5 internally for fast hashing, but it does not use it for security purposes as MD5 is insecure.

See https://learn.microsoft.com/en-us/sharepoint/security-for-sharepoint-server/federal-information-processing-standard-security-standards.

Answer 2

Hi @adil ,

As trevor said, disable FIPS group policy then run PS Config again, here are steps to disable the group policy:

1. Open Local Group Policy Editor (gpedit.msc).
2. Click Computer Configuration> Windows Settings> Security Settings> Local Policies>Security Options.
3. Scroll to 'System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing' (this should not be enabled).
4. Ensure the policy is DISABLED.
5. Repeat on all Windows servers in your FARM which are affected.
6. Perform IIS RESET.
7. Verify the setting and ensure the policy is disabled.
