* Rework DSA_sign() and DSA_verify()tb2022-11-191-20/+31
| | | | | | | | | | | Change DSA_sign() to single exit and check the signed i2d_DSA_SIG() return value before assigning it to an unsigned int. In DSA_verify() let d2i_DSA_SIG() handle the allocation, split error check of i2d_DSA_SIG() from signature check and change an unnecessary freezero() to free. ok jsing
* Fix an annoying quirk in the EC codetb2022-11-1920-243/+243
| | | | | | Dealing with elliptic curves makes some people think that it would be kind of neat to multiply types with variable names. Sometimes. Only in function definitions.

* Remove HMAC PRIVATE KEY supporttb2022-11-191-64/+1
| | | | | | | | This is an undocumented feature of openssl genpkey for testing purposes. Emilia removed support for this 'bogus private key format' from OpenSSL in 2017 in commit c26f655fdd18ac19016c1c0496105f5256a1e84d. ok jsing
* Check os for NULL before dereferencing ittb2022-11-181-5/+5
| | | | | | Avoids a segfault when both priv == NULL and os == NULL. ok miod

* Wire up HMAC to raw private key methodstb2022-11-181-2/+61
| | | | | | | | | | | | | | | Obviously, the brilliant API design kitchen decided that an interface carrying public and private key in its name (so that every sane person thinks of asymmetric cryptography), is also perfectly suitable for MACs. Wire up HMAC since Ruby's OpenSSL gem uses these bindings if the build system detects that EVP_PKEY_new_raw_public_key() is available in evp.h. While there, also add the missing pub_cmp() ameth, which obviously treats two things as equal by returning 1. Reported by jeremy and anton, fixes regress/lib/libssl/openssl-ruby tests ok jsing
* Change the pkey.ptr from char * to void *tb2022-11-186-16/+13
| | | | | | | | Now that EVP_PKEY is opaque, there is no reason to keep the ptr member of the pkey union as a weird char pointer, a void pointer will do. This avoids a few stupid casts and simplifies an upcoming diff. ok jsing

* Prevent Ed25519 signature malleabilitytb2022-11-171-1/+28
| | | | | | | | | | | | Add a check that ensures that the upper half s of an Ed25519 signature is bounded by the group order, i.e, 0 <= s < order. This is required by the Verify procedure in RFC 8032, section 5.1.7, step 1, and prevents simple modifications of signatures such as adding (a multiple of) the group order to the upper half of the signature. Found with EdDSA testcase 63 of project Wycheproof. ok beck jsing

* Mark BN_mod_exp2_mont() as intentionally undocumented.schwarze2022-11-161-3/+4
| | | | | | | | | | | It appears to be intended for internal use by DSA_do_verify(3) and using codesearch.debian.net, i found nothing outside OpenSSL/LibreSSL using it. In April 2018, jsing@ questioned whether the five related functions BN_mod_exp_mont() and friends should even be exposed by <openssl/bn.h>, so we decided to not document them. Now tb@ agrees that there is no reason to document BN_mod_exp2_mont() as long as we don't want to document BN_mod_exp_mont().

| | | | | | | | | | | 1. Explain up front what "ASN1_TIME" is (suggested by beck@, wording by me). 2. For opaque structs, use the generic term "object", like we already do it in many other LibreSSL manual pages. 3. Drop some redundant phrases. 4. Improve the EXAMPLES section (by beck@, with fixes by me). 6. Add a STANDARDS section. ...and some other minor polishing. OK beck@
* Check certificate extensions in trusted certificates.beck2022-11-133-8/+64
| | | | | | | | | | | | | | | | | | Historically the standards let the implementation decide to either check or ignore the certificate properties of trust anchors. You could either use them simply as a source of a public key which was trusted for everything, or you were also permitted to check the certificate properties and fully enforce them. Hooray for freedumb. OpenSSL changed to checking these with : commit 0daccd4dc1f1ac62181738a91714f35472e50f3c Author: Viktor Dukhovni <openssl-users@dukhovni.org> Date: Thu Jan 28 03:01:45 2016 -0500 BoringSSL currently does not check them, as it also inherited the previous OpenSSL behaviour. It will change to check them in the future. (https://bugs.chromium.org/p/boringssl/issues/detail?id=533)

* Expose various EVP hooks for Ed25519 and X25519tb2022-11-131-6/+3
| | | | | | | | This adds the EVP_PKEY_ED25519 and EVP_PKEY_X25519 aliases for the NIDs and exposes the raw public key API. The ED25519_KEYLEN and X25519_KEYLEN defines are still kept internal for now to match what OpenSSL have. We may want to expose those later.
* Add ED25519 aliases for NID, SN and OBJtb2022-11-131-3/+1
| | | | The Ed25519 versions already existed, but OpenSSL chose to uppercase the D.

* Convert the legacy TLS stack to tls_content.jsing2022-11-1110-190/+292
| | | | | | | | | | This converts the legacy TLS stack to tls_content - records are now opened into a tls_content structure, rather than being written back into the same buffer that the sealed record was read into. This will allow for further clean up of the legacy record layer. ok tb@

* Add support for symbol hiding disabled by default.beck2022-11-1110-5/+232
| | | | | | | | | | | | Fully explained in libcrypto/README. TL;DR make sure libcrypto and libssl's function calls internally and to each other are via symbol names that won't get overridden by linking other libraries. Mostly work by guenther@, which will currently be gated behind a build setting NAMESPACE=yes. once we convert all the symbols to this method we will do a major bump and pick up the changes. ok tb@ jsing@
