In retrospect this was the wrong criteria to optimize for. Currently shipping versions of gcrypt have cipher impls that are massively faster than those in nettle and this is way more important. The nettle library is also not capable of enforcing FIPS compliance, since it considers that out of scope. It merely aims to provide general purpose impls of algorithms, and usage policy is left upto the layer above, such as GNUTLS. Reviewed-by: Eric Blake Signed-off-by: Daniel P.
