Check out the git tag OTP-21.0.6, and build a full OTP system
including documentation. Apply one or more applications from this
build as patches to your installation using the 'otp_patch_apply'
tool. For information on install requirements, see descriptions for
each application version below.
The crypto-4.3.2 application can be applied independently of other
applications on a full OTP 21 installation.

OTP-15233 Application(s): crypto
Update the crypto engine functions to handle multiple
loads of an engine.
engine_load/3/4 is updated so it doesn't add the engine
ID to OpenSSLs internal list of engines which makes it
possible to run the engine_load more than once if it
doesn't contain global data.
Added ensure_engine_loaded/2/3 which guarantees that
the engine just is loaded once and the following calls
just returns a reference to it. This is done by add the
ID to the internal OpenSSL list and check if it is
already registered when the function is called.
Added ensure_engine_unloaded/1/2 to unload engines
loaded with ensure_engine_loaded.
Then some more utility functions are added.
engine_add/1, adds the engine to OpenSSL internal list
engine_remove/1, remove the engine from OpenSSL
engine_get_id/1, fetch the engines id
engine_get_name/1, fetch the engine name
