* Merge BN_BLINDING_create_param() into BN_BLINDING_new()tb2023-08-093-33/+16
|
* Set up the blinding factors on first usetb2023-08-091-27/+14
| | | | | | | Only call BN_BLINDING_setup() from BN_BLINDING_update(). This allows another simplification of the counter logic. ok jsing
* Remove retry loop in BN_BLINDING_setup()tb2023-08-091-24/+5
| | | | | | | If we generate a non-invertible blinding, we have accidentally factored the modulus. This won't happen, so get rid of this ugly complication. ok jsing
* Compute a square using BN_mod_sqr() instead of BN_mod_mul()tb2023-08-091-3/+3
| | | | ok jsing
* Simplify BN_BLINDING_invert()tb2023-08-091-14/+5
| | | | | | | If the blinding is non-NULL, Ai is set on it, so no need to check for that. Also, we can get away with a single call to BN_mod_mul(). ok jsing

* Make BN_BLINDING respect some invariantstb2023-08-081-48/+17
| | | | | | | | | | | | Pass e and mod into BN_BLINDING_new() for now and unconditionally allocate A and Ai. This way non-NULL blindings always have these four members set. This allows removing several unnecessary checks in the update, convert and parameter creation code paths. Fix exit BN_BLINDING_create_param() so as to signal errors to the caller if a non-NULL blinding was passed. This fixes a long standing bug. ok jsing
* Simplify RSA_setup_blinding()tb2023-08-081-21/+16
| | | | | | | Make this look a bit more like other code we cleaned up avoiding nesting and unnecessary else branches. ok jsing
* Remove ECDSA nonce padding kludgetb2023-08-081-22/+1
| | | | | | | | | | | This was a workaround due to the historically non-constant time scalar multiplication in the EC code. Since Brumley and Tuveri implemented the Montgomery ladder, this is no longer useful and should have been removed a long time ago, as it now does more harm than good. Keep the preallocations as they still help hiding some timing info. ok jsing
* Fix two leaks in BIO_dup_chain()tb2023-08-071-19/+17
| | | | | | | | If CRYPTO_dup_ex_data() fails, the new_bio is leaked. If an error occurs after the first iteration, all members of the new chain except the head are leaked. ok jsing

* Make the bn_rand_interval() API a bit more ergonomictb2023-08-0310-47/+52
| | | | | | | | | | | | | | | | | | Provide bn_rand_in_range() which is a slightly tweaked version of what was previously called bn_rand_range(). The way bn_rand_range() is called in libcrypto, the lower bound is always expressible as a word. In fact, most of the time it is 1, the DH code uses a 2, the MR tests in BPSW use 3 and an exceptinally high number appears in the Tonelli-Shanks implementation where we use 32. Converting these lower bounds to BIGNUMs on the call site is annoying so let bn_rand_interval() do that internally and route that through bn_rand_in_range(). This way we can avoid using BN_sub_word(). Adjust the bn_isqrt() test to use bn_rand_in_range() since that's the only caller that uses actual BIGNUMs as lower bounds. ok jsing

* Remove the unused flags member of BN_BLINDINGtb2023-08-022-10/+4
| | | | | | | Nothing sets this, so remove it along with BN_BLINDING_NO_{UPDATE,RECREATE} and some checks that are always true. ok jsing

* Remove a 16 year old confusing lietb2023-08-021-2/+2
| | | | | The mod member of BN_BLINDING hasn't been /* just a reference */ since the branch prediction mitigations in OpenSSL bd31fb21 from March 2007.
* Remove more *_options() stufftb2023-07-315-50/+5
| | | | | | | The public symbols were removed. Some prototypes and in the case of DES even the implementation remained. ok jsing
* Move HAVE_FUNOPEN out of !NOPICtb2023-07-291-5/+1
| | | | | | | | Due to some historic accident, HAVE_FUNOPEN was grouped with DSO_DLFCN and HAVE_DLFCN_H inside !defined(NOPIC). While the two DLFCN bits belong there, HAVE_FUNOPEN doesn't. ok jsing, millert agrees

| | | | | Some *_options() prototypes were left behind in headers. I will remove them after my amd64 ports bulk completes.

* Stop including ecdsa.h and ecdh.h internallytb2023-07-288-21/+9
| | | | | | | | These headers are now reduced to #include <openssl/ec.h> and are provided for compatiblity only. There's no point in using them. At the same time garbage collect the last uses of OPENSSL_NO_{ECDSA,ECDH} in our tree. ok jsing
* The CRYPTO_EX_DATA type is not opaquetb2023-07-281-5/+2
| | | | | | | | | By API misdesign, it cannot be opaque. The incorrect documentation was added as a part of a huge commit with a lot of churn. CRYPTO_EX_DATA typically lives as an embedded struct of an opaque struct, but it can also be used by applications, for example to initialize libssl. documentation error pointed out by jsing

* Remove various ${thing}_optionstb2023-07-2812-224/+7
| | | | | | | | | | Various, ancient ciphers exposed some of their innards via an _options() API. Apart from openssl version/speed, only some lua thingie in nmap ever looked at these. Go figure. hppa testing by miod, i386 testing by sthen. Thanks! ok jsing
* Remove more ASN1_BIT_STRING APItb2023-07-285-72/+3
| | | | | | | | | This removes ASN1_BIT_STRING_name_print(), ASN1_BIT_STRING_{num,set}_asc(). Before trust was properly handled using OIDs, there was a period where it used bit strings. The actual interfaces used in openssl x509 were removed, but the functions they wrapped remained unused for the next 24 years. ok jsing
* Remove ASN1_BIT_STRING_checktb2023-07-285-35/+3
| | | | | | | | This was added with the TS code for no discernible reason. I could not find a single consumer. In the unlikely event that you need this, it is easy enough to write a better version of it yourself. ok jsing
* Provide CMS{,_SignerInfo}_get_versiontb2023-07-284-3/+53
| | | | | | | Add accessors for the syntax versions of ContentInfo and SignerInfo. These will be used soon in rpki-client for some more compliance checks. ok job jsing
* Remove sk_nid_triple_*()tb2023-07-281-23/+1
| | | | | | | The nid_triple stack is no more. Its type never was part of the public API. Why its stack macros were will remain a mystery. ok jsing
* Remove OBJ_add_sigid() and OBJ_sigid_free()tb2023-07-285-24/+3
| | | | | | | | Another bit of unused extensibility that was responsible for a lot of complexity until recently. This removes the remaining stubs from the public API. ok jsing
* Remove more ERR crufttb2023-07-285-40/+3
