Subject: [PATCH 1/2] test: disable CEX usage in OpenSSL for all tests
|
|
|
|
OpenSSL supports CEX exploitation since version v3.2.x. Libica and its
|
|
testcases use OpenSSL as helper and fallback, so disable the CEX
|
|
acceleration for all tests.
|
|
|
|
If the environment variable is already set, use it as is without
|
|
modifying it. In this case, it is up to the user to choose the right
|
|
settings.
|
|
|
|
Fixes: Issue #126
|
|
