Revision	Date	Author	Comments
1.4	05-Nov-2022	jmcneill	Make aes and chacha prints debug only.
1.3	27-Jul-2020	riastradh	Simplify ChaCha selection and allow it to be used much earlier. This way we can use it for cprng_fast early on. ChaCha is easy because there's no data formats that must be preserved from call to call but vary from implementation to implementation -- we could even make it a sysctl knob to dynamically select it with negligible cost. (In contrast, different AES implementations use different expanded key formats which must be preserved from aes_setenckey to aes_enc, for example, which means a considerably greater burden on dynamic selection that's not really worth it.)
1.2	27-Jul-2020	riastradh	New sysctl subtree kern.crypto. kern.crypto.aes.selected (formerly hw.aes_impl) kern.crypto.chacha.selected (formerly hw.chacha_impl) XXX Should maybe deduplicate creation of kern.crypto.
1.1	25-Jul-2020	riastradh	New ChaCha API in kernel. This will enable us to adopt MD vectorized implementations of ChaCha.
