crypto: aes_init(): Fail correctly when called with bad key length
...
A proper error code is returned if a key with unsupported (either by the implementation or the AES algorithm) length is passed to aes_init.
This fixes Issue #10175

crypto/helper: Add secure wipe function
...
Adds a cryptographically secure wipe function to wipe structs with
sensitive data. Works by first casting the pointer to a `volatile`
pointer to ensure that the compiler doesn't optimize the "memset" away.

sys: add ChaCha stream cipher and PRNG
...
This implementation is optimized for a little code and data size, not
for speed. IMO the code is more readable than in the reference
implementation.
The biggest advantage of ChaCha over other stream ciphers is the very
little data usage with only 64 bytes of context, and its good encryption
speed.
Also part of this PR is pseudo-random number generator, that just
returns the keystream of a randomly initialized ChaCha context.
