* Minor tweaks in EVP_read_pw_string_min()tb2024-01-051-4/+4
| | | | | Remove unnecessary parentheses and use a better place to break an overlong line.
* Plug a leak in EVP_read_pw_string_min()tb2024-01-051-9/+14
| | | | | | | Use an error exit that frees the ui in case the UI_add_* fail. Also add a few empty lines for readability. ok joshua
* Disable EVP_PKEY_meth_* extensibilitytb2024-01-041-46/+7
| | | | | | | | | | This removes the global pkey_app_methods stack that was never cleaned up and makes EVP_PKEY_meth_add0() always fail and push an error on the stack. EVP_PKEY_meth_find() can now walk the list of PKEY_METHODs forward and things become a bit cleaner. It's still all way more complicated than it needs to be... ok jsing
* Remove last external call to EVP_PKEY_meth_find()tb2024-01-041-5/+6
| | | | | | | | | In order to determine whether GOST is properly enabled, libssl has various weird dances. In this specific case, it calls EVP_PKEY_meth_find() to see whether the relevant cipher is around. Check the same thing with an #ifdef instead. ok jsing
* Remove unused app_data from EVP_CIPHERtb2024-01-0415-84/+15
| | | | | | | | The EVP_CIPHER structs are static const data that the library returns when you call EVP_aes_128_cbc(), for example. It makes no sense whatsoever to hang user data off such a struct, but it's been there since forever. ok jsing
* Clean up EVP_PKEY_asn1_get0_info() a bittb2024-01-041-14/+16
| | | | | Use better variable names without silly p prefix and use explicit checks against NULL.
* Clean up EVP_PKEY_asn1_find_str()tb2024-01-041-9/+18
| | | | | | | | | Use slightly better argument and variable names, do not pointlessly try to match a string of negative length < -1, use a size_t for the strlen() and preserve the logic that allows lookup by a string fragment rather than a full string. ok jsing
* Simplify EVP_PKEY_asn1_find()tb2024-01-041-33/+9
| | | | | | | | | EVP_PKEY_asn1_find() finds the EVP_PKEY_ASN1_METHOD underlying the method or alias with nid (or, rather, pkey_id) passed in. Now that we have the base method stored in a pointer, we can return that method after a simple lookup of said nid (or, rather, pkey_id). ok jsing
* Replace .pkey_base_id with a .base_method pointertb2024-01-0411-32/+32
| | | | | | | | | | | | | | | | Every EVP_PKEY_ASN1_METHOD is either an ASN.1 method or an alias. As such it resolves to an underlying ASN.1 method (in one step). This information can be stored in a base_method pointer in allusion to the pkey_base_id, which is the name for the nid (aka pkey_id aka type) of the underlying method. For an ASN.1 method, the base method is itself, so the base method is set as a pointer to itself. For an alias it is of course a pointer to the underlying method. Then obviously ameth->pkey_base_id is the same as ameth->base_method->pkey_id, so rework all ASN.1 methods to follow that. ok jsing
* Neuter the remainder of the ameth libtb2024-01-041-65/+13
| | | | | | | | | | | The few pieces of the ameth lib that will stay in libcrypto were moved to p_lib.c recently. The functions that still are in ameth_lib.c will be removed in the next major bump. With disabled EVP_PKEY_asn1_add{0,_alias}() API they are completely useless now and they are getting in the way of more ameth surgery. Rip out their guts and turn them into stubs that do nothing but push an error onto the stack. ok jsing
* Split ameth arrays into individual methodstb2024-01-044-149/+150
| | | | | | | | | | | | For some reason DSA, GOST, and RSA had their ASN.1 methods stored in an array. This is clumsy and the only benefit is that one saves a few externs in p_lib.c. They were also arranged by ascending NID because of bsearch() madness. Split them up and arrange the methods by name, which is much saner and simpler. ok jsing
* Improve length checks for oiv and ivtb2024-01-041-4/+5
| | | | | | | | | | There are two unsigned char arrays of size EVP_MAX_IV_LENGTH to store the IVs of block ciphers. In most modes, only iv is used, but in some modes iv is modified and oiv is used to store the original IV. At the moment nothing enforces that they are of the same length. Therefore make sure the correct one or both are checked before writing to or reading from them. ok miod
* Improve order in ancient CMS helperstb2024-01-031-25/+25
| | | | | | | First came EVP_CIPHER_param_to_asn1() which wraps EVP_CIPHER_set_asn1_iv() which was implemented last. Then came EVP_CIPHER_asn1_to_param() wrapping EVP_CIPHER_get_asn1_iv(). Move each param function below the iv function it wraps.
* Move a t to the right place in a commenttb2024-01-021-2/+2

* Match struct order for the EVP_CIPHER_CTX accessorstb2024-01-021-69/+73
| | | | | | This isn't great since the struct is ordered in about the silliest way imaginable, but it is better than it was before. Bringing order into this mess is harder than solving a Rubik's cube.
* Move down EVP_CIPHER_CTX accessors expose EVP_CIPHER internalstb2024-01-021-38/+42
| | | | | These confusingly named getters were added "for convenience" in 1.1. They fit best next to the EVP_CIPHER API.
* Move the trivial EVP_CIPHER getters downtb2024-01-021-31/+35
| | | | | They are now below the CMS ASN.1 IV stuff, but above the EVP_CIPHER_meth* API, which are setters, in a way.
* Simplify EVP_CIPHER_{asn1_to_param,parma_to_asn1}()tb2024-01-021-17/+13
| | | | There's no need for a ret variable and else if/else
* Move the EVP_CIPHER API that only exists for CMS/legacy a bit downtb2024-01-021-121/+125

* sm4: more NULL misspellingstb2024-01-021-4/+4
|
* Two spellings of key length are enoughtb2024-01-021-6/+7
| | | | | | The API is called EVP_CIPHER_CTX_set_key_length() it has an argument called keylen and, the EVP_CIPHER_CTX's member is called key_len. One of the three is trivial to adjust, so do it.
* Rename the poor outlier EVP_CIPHER *e into *ciphertb2024-01-021-3/+3
|
* Better variable names in EVP_CIPHER_type()tb2024-01-021-7/+8
| | | | | The EVP_CIPHER *ctx (yes) is renamed to cipher, otmp becomes an aobj. Change two !ptr to ptr == NULL checks.
* Consistently use ctx for an EVP_CIPHER_CTXtb2024-01-021-36/+36
| | | | Not c (which is most of the time an EVP_CIPHER) or a (?!).
* Fix bounds check in EVP_PKEY_CTX_get_keygen_info()tb2024-01-011-2/+2
| | | | | | | | | Replace > with >= for the upper array bound to disallow a 4 byte overread. For RSA you can read the padding mode and for DH past the DH_PKEY_CTX. Unfortunately, Ruby thought it important to use this, so we can't kill it easily. ok miod

* pkey_is_pss() and pkey_ctx_is_pss() to rsa_ameth.ctb2024-01-012-6/+6
| | | | | These aren't particularly helpful and should probably both be expanded. For now move them to the only place where they are actually used.
* Remove EVP_PKEY's save_type membertb2024-01-012-6/+2
| | | | | | | This was only used to avoid an ameth lookup in EVP_PKEY_set_type(), a micro-optimization that was removed in p_lib.c r1.48. ok jsing

* Sort the NIDs by nametb2023-12-311-8/+8
| | | | requested by jsing
* Replace the sorted extensions lookup with a switchtb2023-12-311-58/+23
| | | | | | | | | If all you have is OBJ_bsearch_(), everything looks like a nail. This changes a binary search over a list of 12 elements with a lookup via a switch. switch suggested by claudio ok jsing
* Sprinkle a handfull of missing continuetb2023-12-311-1/+10

* Make x509_issuer_cache_free_oldest() statictb2023-12-301-2/+2
| | | | | This is an internal function and you can't hold the required mutex to call it anyway since that's internal, too.

* Add extended regress coverage for ASN.1 methodstb2023-12-301-1/+147
| | | | | | | | Validate that every alias resolves to a non-alias in one step and that non-aliases have pkey_id == pkey_base_id, an info string and a pem_str. They can be looked up by their pkey_id or pem_str. Conversely, all these are false for aliases.
* Fix two more unchecked EVP_PKEY_assign() callstb2023-12-301-17/+25
| | | | | | | | | In SSL{_CTX}_use_RSAPrivateKey() switch from EVP_PKEY_assign_RSA() to EVP_PKEY_set1_RSA() and hold on to the reference of the the pkey for the duration of ssl_set_pkey(). Use single exit and other minor style cleanups. ok joshua jsing

|
* Adjust documentation for upcoming DSA_generate_parameters removaltb2023-12-295-70/+17
| | | | | | | This removes any mention of DSA_generate_parameters in the manuals apart from a comment that it is intentionally undocumented and adapts cross references to DSA_generate_parameters_ex. The file itself will be moved in a second step.

* eckey: adjust some variable names and unwrap function definitionstb2023-12-291-11/+8

* Clean up old_ec_priv_decode()tb2023-12-291-10/+17
| | | | | | As per usual. Stylistic adjustments and missing error check. ok jsing
* Clean up eckey_param_decode()tb2023-12-291-9/+16
| | | | | | | | This aligns eckey's parameter decoding routine with the one of other cipher abstractions: better variable names, single exit and add missing check for EVP_PKEY_assign_EC_KEY(). ok jsing
* Rework eckey_priv_decode()tb2023-12-291-49/+53
| | | | | | | | | Factor out the pubkey computation and bring it into more sensible form. This removes lots of pointless setting of errors (twice) and makes the code a bit easier on the eyes. Other than that perform some stylistic cleanup like single exit and add an error check for EVP_PKEY_assign(). ok jsing

* Neuter the SSL_set_debug(3) APItb2023-12-294-21/+5
| | | | | | | | | | | The TLSv1.3 stack didn't support this in the first place, and in the legacy stack it only added some dubious BIO_flush(3) calls. The sleep call between SSL_read(3) and SSL_write(3) advertised in the comment next to the flag has been a sleep call in the s_server since time immemorial, nota bene between calls to BIO_gets(3). Anyway. This can all go and what remains will go with the next major bump. ok jsing
* Garbage collect the last users of SSL_set_debug(3)tb2023-12-292-5/+2
| | | | | | | | This undocumented, incomplete public function has never done anything useful. It will be removed from libssl. Removing it from openssl(1) clears the way for this. ok jsing
