* Mop up the now unused RC4_CHUNK defines.jsing7 days1-10/+0
| | | | ok tb@
* Remove DES_UNROLL from opensslconf.h.jsing2025-07-271-12/+0
| | | | | | This is no longer used in the DES code. ok tb@
* Remove BN_LLONG defines/undefs from opensslconf.h.jsing2025-07-231-5/+0
| | | | | | | These have been ineffective since r1.19 of bn.h, when BN_LLONG/BN_ULLONG defines/undefs were added based on _LP64. ok tb@
* Remove BF_PTRtb2025-06-111-5/+0
| | | | | | | | | | | | In bf_local.h r1.2, openssl/opensslconf.h was pulled out of the HEADER_BF_LOCL_H header guard, so BF_PTR was never defined from opensslfeatures.h. Thus, alpha, mips64, sparc64 haven't used the path that is supposedly optimized for them. On the M3k the speed gain of bf-cbc with BF_PTR is roughly 5%, so not really great. This is blowfish, so I don't think we want to carry complications for alpha and mips64 only. ok jsing kenjiro
* Move (mostly) MI constants to proper headerstb2025-06-091-32/+0
| | | | | | | | | | | | | | | | | Most of the constants here are only defined if a specific header is in scope. So move the machine-independent macros to those headers and lose the header guards. Most of these should actually be typedefs but let's change this when we're bumping the major since this technically has ABI impact. IDEA_INT RC2_INT and RC4_INT are always unsigned int DES_LONG is always unsigned int except on i386 This preserves the existing situation on OpenBSD. If you're using portable on i386 with a compiler that does not define __i386__, there's an ABI break. ok jsing
* Remove ${MULTIPLE_OF_EIGHT}_BIT*tb2025-06-081-12/+0
| | | | | | | | These are unused internally and very few things look at them, none of which should really matter to us, except possibly free pascal on Windows. sizeof has been available since forever... ok jsing
* Garbage collect DES_PTRtb2025-06-081-6/+0
| | | | pointed out by/ok jsing
* Remove DES_RISC*tb2025-06-081-55/+0
| | | | | | | | | | | | | | | codesearch.debian.net only shows some legacy openssl patches plus binkd (a FidoNet mailer) as sole potential user. net-snmp and a strongswan DES plugin bundle some opt-in libdes/openssl legacy things. If this should break any of this, I don't think we need to care. If you're really going to use DES you can also use non bleeding edge libressl. We can remove the big 'default values' block because one of DES_RISC1, DES_RISC2, DES_UNROLL is always defined (you can ignore DES_PTR for this), so this is dead support code for mostly dead platforms. ok kenjiro
* Rename the header guard of des.h with HEADER_DES_Htb2025-06-051-1/+1
| | | | | | libdes is dead, Jim. Only its successors continue to haunt us. discussed with jsing
* Remove preprocessor branching on HEADER_DES_Htb2025-06-051-1/+1
| | | | | | | | This was the header guard for des_old.h introduced in 2002 and removed in 2014. The header guard for des.h is HEADER_NEW_DES_H for the sake of inconsistency (ostensibly due to backward compat concerns with libdes). ok jsing
* opensslconf.h: remove md2 leftoverstb2025-06-051-4/+0
| | | | | | | md2.h left on Apr 15, 2014, along with jpake and seed. In particular, HEADER_MD2_H is never defined. These bits have been dead ever since. ok jsing
* Disable libcrypto assembly on arm.jsing2025-05-245-257/+2
| | | | | | | | | | | | | | | | | The arm CPU capability detection is uses SIGILL and is unsafe to call from some contexts. Furthermore, this is only useful to detect NEON support, which is then unused on OpenBSD due to __STRICT_ALIGNMENT. Requiring a minimum of ARMv7+VFP+NEON is also not unreasonable. The SHA-1, SHA-256 and SHA-512 (non-NEON) C code performs within ~5% of the assembly, as does RSA when using the C based Montgomery multiplication. The C versions of AES and GHASH code are around ~40-50% of the assembly, howeer if you care about performance you really want to use Chacha20Poly1305 on this platform. This will enable further clean up to proceed. ok joshua@ kinjiro@ tb@
* Support OPENSSL_NO_FILENAMEStb2025-03-091-0/+10
| | | | | | | | | | Some people are concerned that leaking a user name is a privacy issue. Allow disabling the __FILE__ and __LINE__ argument in the error stack to avoid this. This can be improved a bit in tree. From Viktor Szakats in https://github.com/libressl/portable/issues/761 ok bcook jsing
* Replace Makefile based SHA*_ASM defines with HAVE_SHA_* defines.jsing2025-02-142-4/+10
| | | | | | | | | | | | | | | | Currently, SHA{1,256,512}_ASM defines are used to remove the C implementation of sha{1,256,512}_block_data_order() when it is provided by assembly. However, this prevents the C implementation from being used as a fallback. Rename the C sha*_block_data_order() to sha*_block_generic() and provide a sha*_block_data_order() that calls sha*_block_generic(). Replace the Makefile based SHA*_ASM defines with two HAVE_SHA_* defines that allow these functions to be compiled in or removed, such that machine specific verisons can be provided. This should effectively be a no-op on any platform that defined SHA{1,256,512}_ASM. ok tb@
* Mop up RC4_INDEX.jsing2025-01-271-7/+0
| | | | | | | | | | | | | The RC4_INDEX define switches between base pointer indexing and per-byte pointer increment. This supposedly made a huge difference to performance on x86 at some point, however compilers have improved somewhat since then. There is no change (or effectively no change) in generated assembly on a the majority of LLVM platforms and even when there is some change (e.g. aarch64), there is no noticable performance difference. Simplify the (still messy) macros/code and mop up RC4_INDEX. ok tb@
* cryptlib.h: adjust header guard for upcoming surgerytb2024-11-051-1/+1
| | | | | | | | It is gross that an internal detail leaked into a public header, but, hey, it's openssl. No hack is too terrible to appear in this library. opensslconf.h needs major pruning but the day that happens is not today. ok jsing
* repair bizzare indents; ok tbderaadt2024-08-291-2/+6

* Provide and use crypto_arch.h.jsing2024-08-112-4/+30
| | | | | | | | Provide a per architecture crypto_arch.h - this will be used in a similar manner to bn_arch.h and will allow for architecture specific #defines and static inline functions. Move the HAVE_AES_* and HAVE_RC4_* defines here. ok tb@
* Always use C functions for AES_{encrypt,decrypt}().jsing2024-03-291-0/+2
| | | | | | | Always provide AES_{encrypt,decrypt}() via C functions, which then either use a C implementation or call the assembly implementation. ok tb@
* Move camellia to primary Makefile.jsing2024-03-291-2/+0
| | | | These files are now built on all platforms.
* Move aes_core.c to the primary Makefile.jsing2024-03-291-1/+0
| | | | This is now built on all platforms.
* Always use C functions for AES_set_{encrypt,decrypt}_key().jsing2024-03-291-0/+3
| | | | | | | | Always include aes_core.c and provide AES_set_{encrypt,decrypt}_key() via C functions, which then either use a C implementation or call the assembly implementation. ok tb@
* Move wp_block.c to the primary Makefile.jsing2024-03-291-2/+0

* Move rc4.c to primary Makefile.jsing2024-03-281-2/+0
| | | | This is now built on all platforms.
* Move des sources to primary Makefile.jsing2024-03-281-2/+0
| | | | | Now that all platforms use a C des implementation, move it to the primary Makefile.
* Consolidate rc4 code.jsing2024-03-271-1/+1
| | | | Discussed with tb@
* Move bf_enc.c to the primary Makefile.jsing2024-03-271-2/+0
| | | | | Now that all architectures are using bf_enc.c, it does not make sense to have it in every Makefile.inc file.
* Remove constructor attribute for OPENSSL_cpuid_setup() on arm/aarch64.jsing2023-07-261-5/+1
| | | | | | | | OPENSSL_cpuid_setup() is invoked via OPENSSL_init_crypto(), whihc is triggered by various entry points to the library. As such, we do not need to invoke it as a constructor. ok tb@
* Stop building GF2m assemblytb2023-04-151-2/+0
| | | | | | | GF2m support will be removed shortly. In the interim drop some of this unused code already and let it fall back to the C implementation. ok jsing
* Remove the now empty bn_asm.c.jsing2023-01-311-1/+0
| | | | | | This rather misnamed file (bn_asm.c) previously contained the C code that was needed to build libcrypto bignum on platforms that did not have assembly implementations of the functions it contained.
* Remove non-visible and unused OPENSSL_wipe_cpu and OPENSSL_atomic_addmiod2023-01-171-96/+0
| | | | | | | interfaces, and remove empty assembly OPENSSL_cpuid_setup routines - the default empty C fallback will work as good. ok jsing@
* Remove unused Elliptic Curve code.jsing2023-01-141-4/+0
| | | | | | | | | | | | | For various reasons, the ecp_nistp* and ecp_nistz* code is unused. While ecp_nistp* was being compiled, it is disabled due to OPENSSL_NO_EC_NISTP_64_GCC_128 being defined. On the other hand, ecp_nistz* was not even being built. We will bring in new versions or alternative versions of such code, if we end up enabling it in the future. For now it is just causing complexity (and grep noise) while trying to improve the EC code. Discussed with tb@

* Start disentangling armv7 and aarch64 codetb2022-03-233-0/+312
| | | | | | | | | arm_arch.h and armcap.c are shared between armv7 and aarch64 which results in an inscrutable #ifdef maze. Move copies of these files into arch/{arm,aarch64}/ with appropriate names and some trivial minor adjustments. ok deraadt inoguchi kettenis

* Disable ENGINE_load_dynamic (dynamic engine support).bcook2015-06-191-1/+0
| | | | | | | We do not build, test or ship any dynamic engines, so we can remove the dynamic engine loader as well. This leaves a stub initialization function in its place. ok beck@, reyk@, miod@
* Add the Cammelia cipher to libcrypto.miod2014-11-171-0/+2
| | | | | | | | | | | | | | | | | | There used to be a strong reluctance to provide this cipher in LibreSSL in the past, because the licence terms under which Cammelia was released by NTT were free-but-not-in-the-corners, by restricting the right to modify the source code, as well retaining the right to enforce their patents against anyone in the future. However, as stated in http://www.ntt.co.jp/news/news06e/0604/060413a.html , NTT changed its mind and made this code truly free. We only wish there had been more visibility of this, for we could have had enabled Cammelia earlier (-: Licence change noticed by deraadt@. General agreement from the usual LibreSSL suspects. Crank libcrypto.so minor version due to the added symbols.
