| | | | | We need stdint.h for uintptr_t, stdlib.h for malloc, ec.h for various things, but there's no need for objects. or sha.h.

* Use BN_bn2binpad() instead of handrolling ittb2023-07-011-5/+3
| | | | | | | | | | As ugly as the BN_bn2binpad() internals are, what it does is quite handy with all sorts of EC stuff. So use it here too and eliminate some ugly manual pointer zeroing and offsets. Also switch len and buflen from size_t to int to remove an iffy cast: both are set by functions that return a non-negative int. ok jsing
* Remove unused y from ECDH key computationtb2023-07-011-5/+5

* Remove unneeded bn_local.h and drop a NULL checktb2023-06-251-5/+3

* Remove ech_local.htb2023-06-251-65/+0

* Stop including ech_local.htb2023-06-252-3/+4
|
* Move ecdh_KDF_X9_63() to ec_local.htb2023-06-251-7/+1
| | | | | In anticipation of merging ecdh/ and ecdsa/ into ec/, move the last remaining thing in ech_local.h where it will soon belong.
* Move ECDH_size() to ech_key.ctb2023-06-252-8/+8
| | | | | This way the public ECDH API that will remain in libcrypto is in one file and the public ECDH API that will go is in the other one.
* Move the ecdh_method struct declaration to ech_lib.ctb2023-06-252-11/+10
| | | | No other file uses this anymore
* Move ECDH_OpenSSL() ECDSA_OpenSSL() to *_lib.ctb2023-06-252-13/+13
| | | | | | Now that they no longer use static methods, they can move where they belong. Also make the static method const, as it should have been all along.
* Remove {ecdh,ecdsa}_check() and {ECDH,ECDSA}_DATAtb2023-06-252-109/+2
| | | | | | | This is now unused code. Removing it will free us up to remove some other ugliness in the ec directory. ok jsing
* Remove method wrappers that use {ecdh,ecdsa}_check()tb2023-06-251-21/+4
| | | | | | | | Now that it is no longer possible to set a custom {ECDH,ECDSA}_METHOD, EC_KEY_METHOD can just call the relevant method directly without the need for this extra contortion. ok jsing
* Make ECDH and ECDSA ex_data handlers always failtb2023-06-251-13/+4
| | | | | | | | They will be removed in the next major bump. No port uses them. They use code that is in the way of upcoming surgery. Only libtls and smtpd used to use the ECDSA version. ok jsing
* Make {ECDH,ECDSA}_set_method() always failtb2023-06-251-14/+2
| | | | | | | | They will be removed in the next major bump. No port uses them. They use code that is in the way of upcoming surgery. Only libtls used the ECDSA version, but thankfully op cleaned that up. ok jsing

* Move EC_KEY_{insert,set}_key_method_data() to internal-onlytb2023-04-251-2/+4

* Move some includes out of OPENSSL_NO_DEPRECATEDtb2023-04-181-3/+1
| | | | | | | | | | | | | Some headers were included conditionally on OPENSSL_NO_DEPRECATED in hopes that eventually the mess of everything includes everything will magically resolve itself. Of course everyone would end up building openssl with OPENSSL_NO_DEPRECATED over time... Right. Surprisingly, the ecosystem has come to rely on these implicit inclusions, so about two dozen ports would fail to build because of this. Patching this would be easy but really not worth the effort. ok jsing
* Make header guards of internal headers consistenttb2022-11-261-4/+4
| | | | | Not all of them, only those that didn't leak into a public header... Yes.
* Make internal header file names consistenttb2022-11-264-8/+8
| | | | | | | | | | | | | | | | Libcrypto currently has a mess of *_lcl.h, *_locl.h, and *_local.h names used for internal headers. Move all these headers we inherited from OpenSSL to *_local.h, reserving the name *_internal.h for our own code. Similarly, move dtls_locl.h and ssl_locl.h to dtls_local and ssl_local.h. constant_time_locl.h is moved to constant_time.h since it's special. Adjust all .c files in libcrypto, libssl and regress. The diff is mechanical with the exception of tls13_quic.c, where #include <ssl_locl.h> was fixed manually. discussed with jsing, no objection bcook
* Remove mkerr.pl remnants from LibreSSLkn2022-07-122-12/+2
| | | | | | | This script is not used at all and files are edited by hand instead. Thus remove misleading comments incl. the obsolete script/config. Feedback OK jsing tb

* Elliptic curve arithmetic only makes sense between points that belong totb2018-09-021-1/+5
| | | | | | | | | | | | the same curve. 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
* make ENGINE_finish() succeed on NULL and simplify callers as intb2018-04-141-8/+5
| | | | | | | | | | | OpenSSL commit 7c96dbcdab9 by Rich Salz. This cleans up the caller side quite a bit and reduces the number of lines enclosed in #ifndef OPENSSL_NO_ENGINE. codesearch.debian.net shows that almost nothing checks the return value of ENGINE_finish(). While there, replace a few nearby 'if (!ptr)' with 'if (ptr == NULL)'. ok jsing, tested by & ok inoguchi
* use freezero() instead of memset/explicit_bzero + free. Substantiallyderaadt2017-05-021-4/+2
| | | | | | | | | | reduces conditional logic (-218, +82). MOD_EXP_CTIME_MIN_CACHE_LINE_WIDTH cache alignment calculation bn/bn_exp.c wasn'tt quite right. Two other tricky bits with ASN1_STRING_FLAG_NDEF and BN_FLG_STATIC_DATA where the condition cannot be collapsed completely. Passes regress. ok beck
* Send the function codes from the error functions to the bit bucket,beck2017-01-293-22/+17
| | | | | | as was done earlier in libssl. Thanks inoguchi@ for noticing libssl had more reacharounds into this. ok jsing@ inoguchi@
* Explicitly export a list of symbols from libcrypto.jsing2016-12-211-7/+3
| | | | | | | | | | | | | | | | Move the "internal" BN functions from bn.h to bn_lcl.h and stop exporting the bn_* symbols. These are documented as only being intended for internal use, so why they were placed in a public header is beyond me... This hides 363 previously exported symbols, most of which exist in headers that are not installed and were never intended to be public. This also removes a few crusty old things that should have died long ago (like _ossl_old_des_read_pw). But don't worry... there are still 3451 symbols exported from the library. With input and testing from inoguchi@. ok beck@ inoguchi@
