Subject: [PATCH 55/57] rsa: modify the default algorithm of keygen soft
|
|
algorithm
|
|
|
|
When the hardware algorithm execution fails, the engine needs to
|
|
switch to the soft algorithm execution, and the callback needs to
|
|
be modified to the soft algorithm to prevent it from being
|
|
re-transferred to the hardware interface.
