* Pull up zeroing of out; drop unnecessary checktb2023-07-281-4/+3
| | | | | | | Move the zeroing of the output buffer a few lines up and remove an unnecessary check. requested/ok jsing
* Rename buflen to buf_len, use calloc/freezerotb2023-07-281-7/+8
| | | | | | | Some cosmetic tweaks in ecdh_compute_key(). Rename buflen to buf_len to match out_len, use calloc() and freezero(). ok jsing
* Move KDF handling to ECDH_compute_key()tb2023-07-281-31/+55
| | | | | | | | | | In OpenSSL e2285d87, the KDF handling was moved from the compute_key() method into the public API. A consequence of this change is that the ECDH_compute_key() API no longer returns -1 for some errors. Existing checks for <= 0 are safe as are those checking for the exact length as return value, which is all what the ecosystem seems to be doing. ok jsing
* Fix two EC_POINT_is_on_curve() checkstb2023-07-241-2/+2
| | | | | | | This API can fail for various reasons, in which case it returns -1, so you need to check if (EC_POINT_is_on_curve_checks(...) <= 0). ok miod
* Revert accidental addition of cofactor ECDH supporttb2023-07-121-16/+2
| | | | This snuck in with ech_key.c r1.33 because I committed from a dirty tree.
* Hide symbols in hkdf, evp, err, ecdsa, and ecbeck2023-07-071-1/+3
| | | | | | (part 2 of commit) ok jsing@
* Mop up last uses of ECDHerror() and ECDSAerror()tb2023-07-051-6/+6
| | | | ok jsing
* ECDHerror() and ECDSAerror will go awaytb2023-07-051-8/+8
| | | | | | Move some trivial ones to ECerror(). discussed with jsing
* Merge ECDH code that will stay into ecdh.ctb2023-07-051-0/+272
