Subject: [CRYPTO]: Use template keys for speed tests if possible
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dce907c00ff246a1fbb2b619964753ebc046591d;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[CRYPTO]: Use template keys for speed tests if possible

The existing keys used in the speed tests do not pass the 3DES quality check.
This patch makes it use the template keys instead.

Other algorithms can supply template keys through the same interface if needed.
