Subject: [PATCH] SCP03 support: fix Key Changeover with HSM (RHCS)
|
|
|
632623 |
|
|
|
632623 |
Ticket #2764.
|
|
|
632623 |
|
|
|
632623 |
This relatively simple fix involves making sure the correct crypto token is being used to search for the master key int the case of symmetric key changover where the master key resides on an HSM.
|
|
|
632623 |
|
|
|
632623 |
(cherry picked from commit 7eb8ac9abb06d5a21c9d81d3f7fd08391a2a745e)
