Erlang/OTP 21.0.6

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 internal list

engine_get_id/1, fetch the engines id

engine_get_name/1, fetch the engine name

OTP-15215

Application(s):

inets

Change status code for no mod found to handle request to 501

The ssl-9.0.1 application can be applied independently of other applications on a full OTP 21 installation.

OTP-15203

Application(s):

ssl

Correct cipher suite handling for ECDHE_*, the incorrect handling could cause an incorrrect suite to be selected and most likly fail the handshake.
