* 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.

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.
* Remove unnecessary memcpy for PKI crypto
* Update comment s/packet_id/id/
* Create a copy of bytes for each channel decrypt

* Re-implement PKI from #1509
co-authored-by: edinnen <ethanjdinnen@protonmail.com>
* Set the key lengnth to actually make PKI work.
* Remove unused variable and initialize keys to null
* move printBytes() to meshUtils
* Don't reset PKI key son reboot unless needed.
* Remove double encryption for PKI messages
* Cleanup encrypt logic
* Add the MESHTASTIC_EXCLUDE_PKI option, and set it for minimal builds. Required for STM32 targets for now.
* Use SHA-256 for PKI key hashing, and add MESHTASTIC_EXCLUDE_PKI_KEYGEN for STM32
* Fix a crash when node is null
* Don't send PKI encrypted packets while licensed
* use chIndex 8 for PKI
* Don't be so clever, that you corrupt incoming packets
* Pass on channel 8 for now
* Typo
* Lock keys once non-zero
* We in fact need 2 scratch buffers, to store the encrypted bytes, unencrypted bytes, and decoded protobuf.
* 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)
* Adds SecurityConfig protobuf
* 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
