Ondřej Surý f3753d591f Use thread_local EVP_MD_CTX in isc_iterated_hash() ... As this code is on hot path (NSEC3) this introduces an additional optimization of the EVP_MD API - instead of calling EVP_MD_CTX_new() on every call to isc_iterated_hash(), we create two thread_local objects for each thread - a basectx and mdctx, initialize basectx once and then use EVP_MD_CTX_copy_ex() to flip the initialized state into mdctx. This saves us couple more valuable microseconds from the isc_iterated_hash() call.		2023-01-18 19:36:21 +01:00
