Some Wycheproof tests violate this assumption, making ECDH_compute_key() compute and return garbage. Check that pub_key lies on the curve of the private key so that the calculations make sense. Most paths that get here have this checked (in particular those from OpenSSH and libssl), but one might get here after using d2i_* or manual computation. discussed with & ok jsing; "good catch!" markus Send the function codes from the error functions to the bit bucket, 2017-01-29T17:49:23+00:00 beck 2017-01-29T17:49:23+00:00 urn:sha1:d1f47bd292f36094480caa49ada36b99a69c59b0 as was done earlier in libssl.
