progress to be made since the hardware can fail.

time.  That is, we would have crypto_cipher/crypto_digest instead of
just crypto_tfm.  The appropriate type would then be required for the
actual operations such as crypto_digest_digest.

wants.  However, crypto_alloc_tfm currently does not expose these new
