I thought that the ctx needs to be available for implementations to store private data.

This way we can allocate and store any type of key in the <alg>_parse_key() helper and still have the cxt
available for implementations to use for their stuff (e.g. HW context).

No for symmetric key algorithms we always store the key in the
context and never in the tfm proper.

Think about it, the generic tfm doesn't have any idea on what
the key contains so how can it store it? Only the implementation
knows the key format and can store it in a useful way.

Ok I wanted to handle everything in the parse_key helper without any help from the implementation.
I can change the helper to return the key and implementation will store it in the ctx. Is this
what you are suggesting?
