Subject: apps/apps.c: initialize and de-initialize engine around key loading
X-Git-Tag: OpenSSL_1_1_1-pre1~3441
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=49e476a5382602d0bad1139d6f1f66ddbc7959d6;p=oweals%2Fopenssl.git

apps/apps.c: initialize and de-initialize engine around key loading

Before loading a key from an engine, it may need to be initialized.
When done loading the key, we must de-initialize the engine.
(if the engine is already initialized somehow, only the reference
counter will be incremented then decremented)
