Subject: [PATCH] wolfssl: add RNG to EC key
|
|
|
|
Since upstream commit 6467de5a8840 ("Randomize z ordinates in
|
|
scalar mult when timing resistant") WolfSSL requires a RNG for
|
|
the EC key when built hardened which is the default.
|
|
|
|
Set the RNG for the EC key to fix connections for OWE clients.
|
