* EC_POINT_is_on_curve() error is -1, not 0.tb2023-07-251-2/+2

* Tweak previous. Should have been 60 instead of 64tb2023-07-221-3/+3
|
* Adapt bn_print() for EdDSA key printingtb2023-07-221-7/+40
| | | | | | | | This is essentially a reimplementation of ASN1_buf_print(). The latter was only added for these printing purposes and it will be removed again since nothing uses it. We can then simply remove t_pkey.c in the upcoming bump. ok jsing
* Unbreak the namespace build after a broken mk.conf and tool misfire hadbeck2023-07-073-26/+3
| | | | | | | | me aliasing symbols not in the headers I was procesing. This unbreaks the namespace build so it will pass again ok tb@
* Hide symbols in hkdf, evp, err, ecdsa, and ecbeck2023-07-0713-13/+157
| | | | | | (part 2 of commit) ok jsing@
* Mop up remaining uses of ASN1_bn_print()tb2023-07-071-17/+6
| | | | | | | This removes lots of silly buffers and will allow us to make this API go away. ok jsing
* Convert ecpk_print_explicit_parameters() to bn_printf()tb2023-07-061-34/+8
| | | | | | | This eliminates a few stupid dances the horrible ASN1_bn_print() API required. ok jsing
* don't return in a void functionbcook2023-07-051-2/+2
| | | | ok tb@
* Mop up last uses of ECDHerror() and ECDSAerror()tb2023-07-052-2/+12

* Drop useless ossl_ prefixestb2023-07-053-15/+15
| | | | discussed with jsing
* Explicit parameter printing can also use get0_order()tb2023-07-031-5/+6
| | | | ok beck jsing
* Convert ossl_ec_key_gen() and EC_KEY_check_key()tb2023-07-031-23/+6
| | | | | | These also get the EC_GROUP_get0_order() treatment ok beck jsing
* Convert EC_GROUP_check() to EC_GROUP_get0_order()tb2023-07-031-10/+3
| | | | ok beck jsing
* Inline two copies of EC_GROUP_order_bits()tb2023-07-031-22/+6
| | | | | | | This code is way more complicated than it needs to be. Simplify. ec_bits() was particularly stupid. ok beck jsing
* Provide internal-only EC_GROUP_get0_order()tb2023-07-032-3/+11
| | | | ok jsing
* Fix return values of ecx methodstb2023-07-021-5/+5
| | | | | | | | | It is hard to get your return values right if you choose them to be a random subset of {-2, ..., 3}. The item_verify() and the digestverify() methods don't return 0 on error, but -1. Here 0 means "failed to verify", obviously. ok jsing
* Fix typo in previoustb2023-07-021-2/+2
|
* Use asprintf() to avoid repetition in string constantstb2023-07-021-6/+13
| | | | | | ... since ASN1_bn_print() is stupid. ok jsing
* Split ECPKParameters_print()tb2023-07-021-121/+150
| | | | | | | | | This function has two entirely independent parts, so instead of a huge if/else just use two functions. In ecpk_print_explicity parameters() do some additional boring cleanup such as switching to actually using the local BN_CTX and shuffling things into a slightly more sensible order. ok jsing
* Simplify ASN1_bn_print() usage in ec/tb2023-07-012-30/+20
| | | | | | | ASN1_bn_print() doesn't print anything if the BIGNUM passed in is NULL. Also simplify the handling of the point conversion form of the generator. ok jsing
* whitespacetb2023-06-301-2/+2
|
* Remove some dead code from ECPKParameters_print()tb2023-06-271-31/+6
| | | | | | | This code is unreachable since binary curve support was removed. There is a lot more to clean up in here... ok jsing
* Remove the now unused poly[] from EC_GROUPtb2023-06-271-15/+2
| | | | | | | This was needed for defining the multiplication over binary fields. Since that code is gone, this is no longer needed. ok jsing
* Simplify EC_GROUP_get_basis_type()tb2023-06-271-18/+2
| | | | | | | | The remaining EC_METHODs in libcrypto all have a field type of NID_X9_62_prime_field, so this function always returns 0. Make that more obvious. ok jsing
* Stop including ech_local.htb2023-06-251-2/+1
|
* Remove prototypes for EC_KEY_{get,insert}_key_method_data()tb2023-06-251-8/+1
| | | | These were accidentally left behind in a previous commit.
* Move ecdh_KDF_X9_63() to ec_local.htb2023-06-251-1/+7
| | | | | In anticipation of merging ecdh/ and ecdsa/ into ec/, move the last remaining thing in ech_local.h where it will soon belong.
* Remove EC_EXTRA_DATAtb2023-06-254-230/+4
| | | | | | | | | | | With the ecdh_check() and ecdsa_check() abominations gone, we can finally get rid of EC_EXTRA_DATA and EC_KEY_{get,insert}_key_method_data(). The EC_EX_DATA_*() handlers, (which fortunately have always had "'package' level visibility") join the ride to the great bit bucket in the sky. Thanks to op for making this possible. ok jsing
* ec_local.h: move ec_group_simple_order_bits down a bittb2023-06-251-3/+2
|
* Remove precompute_mult/have_precompute_mult from EC_METHOD.jsing2023-06-242-26/+4
| | | | | | | These are no longer in use - stub EC_GROUP_precompute_mult() and EC_GROUP_have_precompute_mult() to match their existing behaviour. ok tb@
* Mop up EC_GROUP precomp machinery.jsing2023-06-243-252/+10
| | | | | | | | | | | Since there are now no EC implementations that perform pre-computation at the EC_GROUP level, remove all of the precomp machinery, including the extra_data EC_GROUP member. The ec_wNAF_mul() code is horrific - simply cut out the precomp code, rather than trying to rewrite it (that's a project for another day). ok tb@
* Mop up ec_wNAF_{,have_}precompute_mult().jsing2023-06-242-206/+2
| | | | | | | | These were previously called by GF2m code and are no longer used. Also remove ec_pre_comp_new(), since it is only called by ec_wNAF_precompute_mult() and is now unused. ok tb@
* Fix return check for BN_hex2bn()tb2023-06-231-2/+2
| | | | | | | | Purely cosmetic change taking into account the fact that this function returns a length rather than a boolean. This is the last offender in the library. ok jsing
* Consolidate elliptic curve cofactor handlingtb2023-06-201-49/+41
| | | | | | | | | | | | | The various checks of the cofactor to be set in EC_GROUP_set_generator() are a bit all over the place. Move them into a single function and clean things up a little. Instead of calculating directly with the cofactor member of the group, use a temporary variable and copy this variable only if all tests passed. In cryptographic contexts the cofactor almost always fits if not into a single byte then into a word, so copying is cheap. Also streamline the computations a bit and remove some binary curve contortions. ok jsing
* Remove prototypes for various ec_GF2m_* functions that no longer exist.jsing2023-06-121-13/+1
|
* Rewrite ECParameters_dup()tb2023-05-041-7/+12
| | | | | | | This should leak slightly less than the direct expansion of ASN1_dup_of(). Use freezero() since the DER could contain a private key. ok jsing
* Use size_t instead of int in EC_POINT_point2oct()tb2023-05-041-2/+2
| | | | | | | An int would be perfectly sufficient for this, but then again there would be fewer traps. ok jsing

| | | | ok jsing
* Simplify EC_GROUP_new_by_curve_name()tb2023-05-021-20/+14
| | | | | | | | | | | | | Pull the setting of the name a.k.a. nid into ec_group_new_from_data(). This way, we can return early on finding the nid in the curve_list[]. This also avoids a silly bug where a bogus ERR_R_UNKNOWN_BUG is pushed onto the error stack when ec_group_new_from_data() failed. While there rework the exit path of ec_group_new_from_data() a bit. Instead of an ok variable we can use an additional pointer to keep track of the return value and free the EC_GROUP unconditionally. ok jsing
