8 tests fail on a FIPS enabled system #1897

Description

@PritamDutt

When using werkzeug on a linux system with FIPS enabled, following tests fail:

FAILED tests/test_debug.py::TestDebugHelpers::test_exc_divider_found_on_chained_exception - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips
FAILED tests/test_debug.py::test_basic[True] - assert 'The debugger caught an exception in your WSGI application' in '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">\n<title>500 Internal Server Error</title>\n<h1>Internal Serve...

FAILED tests/test_http.py::TestHTTPUtility::test_is_resource_modified_for_range_requests - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips
FAILED tests/test_security.py::test_password_hashing - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips
FAILED tests/test_wrappers.py::test_etag_response_mixin - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips
FAILED tests/test_wrappers.py::test_etag_response_412 - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips
FAILED tests/test_wrappers.py::test_etag_response_mixin_freezing - ValueError: [digital envelope routines: EVP_DigestInit_ex] disabled for fips

These tests have been run after cloning this project.

Environment:

  • Python version: 3.8.0
  • Werkzeug version: master branch

The root cause for failure of these tests appear to be MD5, as it does not appear in the list of approved hashing algorithms (SHA-1, SHA-224, SHA-256, SHA-384, SHA512, SHA-512/224 and SHA-512/256).

Is it a possibility to migrate to SHA1 for hashing?
