Symptom: Using an old context (that had already been passed as argument to either
hmac_upgrade or hmac_final) could cause VM crash or worse.
Reason: Only a shallow copy (memcpy) of the context was made causing
a new context to partly mutate its parent context into an inconsistent
state.
Problem: Only OpenSSL v1.0 supports deep copy of hmac context. It is thus
not possible to implement a functional interface for older OpenSSL
versions (0.9.8) which still have wide spread use.
Solution: Change hmac contexts into a mutable state using NIF resources.
Document reuse of old contexts as undefined.
Future: If a need for reusing old context variables arise, a new hmac_copy
function could be introduced that is only supported for OpenSSL v1.0.

Nice crash instead of segv or worse.

The processes where a legacy from the time when crypto was
implemented with a driver.

Newer OpenSSL versions allow to selectively disable GF2m elliptic curves.
Selectively enable GF2m curves is support for them is available.
|
|
|
|
RFC-5649, Section 1, documents the advantages that these curves
might have over others (ANSI, SEC1/2)
|
|
Decouple eliptic curve definition from OpenSSL and define them in
Erlang.

enif_open_resource_type() must be called even during repeated loading
of same library. Otherwise the resource type will be deallocated
when the old module instance is purged.
