7221fc4d4b Delete unused code (#9350)
* Delete unused code

CryptoEngine::clearKeys() is not used in the code base, therefore this
cleanup removes the code. It might give casual reviewers the impression,
that keys are wiped.

Since the code uses memset() which might be optimized away by the
compiler, using the code might not even cause the memory
to be wiped.

* Update CryptoEngine.cpp

Fix stray newline, this is the only thing that I can come up with that might confuse the linter.

JorropoandGitHub beb268ff25 Revert "add a .clang-format file (#9154)" (#9172)
I thought git would be smart enough to understand all the whitespace changes but even with all the flags I know to make it ignore theses it still blows up if there are identical changes on both sides.

I have a solution but it require creating a new commit at the merge base for each conflicting PR and merging it into develop.

I don't think blowing up all PRs is worth for now, maybe if we can coordinate this for V3 let's say.

This reverts commit 0d11331d18.

Tom FifieldandGitHub ae27aaaf43 Remove unnecessary null pointer checks (#6358)
As reported by @elfring, we had several points in our code where
it was unnecessary to check pointers were non-null before deleting them.

lizthedeveloperandGitHub 4a6a0efcfd log the nonce value at DEBUG instead of INFO (#6001)
you're leaking the nonce to stdout, if your logs are routed to a folder, this logs the nonce every time, leading to replay attack surface area being higher. Changed to debug.

* Remove double encryption for PKI messages

* Cleanup encrypt logic

* use chIndex 8 for PKI

* Don't be so clever, that you corrupt incoming packets

* Lighter approach to retaining known key

* Attach the public key to PKI decrypted packets in device memory

* Turn PKI back off for STM32 :(

* Don't just memcp over a protobuf

* Don't PKI encrypt nodeinfo packets

* Add a bit more memory logging around nodeDB

* Use the proper macro to refer to NODENUM_BROADCAST

* Typo fix

* Don't PKI encrypt ROUTING (naks and acks)

* Add admin messages over PKI

* Disable PKI for the WIO-e5

* Add MINIMUM_SAFE_FREE_HEAP macro and set to safe 1.5k

* Add missed "has_security"

* Add the admin_channel_enabled option

* STM32 again

* add missed configuration.h at the top of files

* Add EXCLUDE_TZ and RTC

* Enable PKI build on STM32 once again

* Attempt 1 at moving PKI to aes-ccm

* Fix buffers for encrypt/decrypt

* Eliminate unused aes variable

* Add debugging lines

* Set hash to 0 for PKI

* Fix debug lines so they don't print pointers.

* logic fix and more debug

* Rather important typo

* Check for short packets before attempting decrypt

* Don't forget to give cryptoEngine the keys!

* Use the right scratch buffer

* Cleanup

* moar cleanups

* Minor hardening

* Remove some in-progress stuff

* Turn PKI back off on STM32

* Return false

* 2.5 protos

* Sync up protos

* Add initial cryptography test vector tests

* re-add MINIMUM_SAFE_FREE_HEAP

* Housekeeping and comment fixes

* Add explanatory comment about weak dh25519 keys
