It's improved since I last looked at it, but there are still many structures
that aren't described:

- struct crypto_instance
- struct crypto_spawn
- struct crypto_blkcipher
- struct blkcipher_desc
- More on the context structures returned by crypto_tfm_ctx

Also not mentioned in the documentation is that some algorithms *do*
have different implementations depending on key size.  SHA-2 is the
classic example.
