* Provide an accelerated SHA-512 assembly implementation for aarch64.jsing2025-03-122-2/+7
| | | | | | | | | | This provides a SHA-512 assembly implementation that makes use of the ARM Cryptographic Extension (CE), which is found on many arm64 CPUs. This gives a performance gain of up to 2.5x on an Apple M2 (dependent on block size). If an aarch64 machine does not have SHA512 support, then we'll fall back to using the existing C implementation. ok kettenis@ 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
* Provide an accelerated SHA-256 assembly implementation for aarch64.jsing2025-03-072-2/+9
| | | | | | | | | | This provides a SHA-256 assembly implementation that makes use of the ARM Cryptographic Extension (CE), which is found on many arm64 CPUs. This gives a performance gain of up to 7.5x on an Apple M2 (dependent on block size). If an aarch64 machine does not have SHA2 support, then we'll fall back to using the existing C implementation. ok kettenis@ 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@

* Replace aarch64 CPU capabilities detection code.jsing2024-11-086-261/+114
| | | | | | | | | | | | Replace the aarch64 CPU detection code with a version that parses ISAR0, avoiding signal handling and SIGILL. This gets ISAR0 via sysctl(), but this can be adapted to other mechanisms for other platforms (or alternatively the same can be achieved via HWCAP). This now follows the same naming/design as used by amd64 and i386, hence define HAVE_CRYPTO_CPU_CAPS_INIT for aarch64. ok kettenis@ 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

* Provide and use crypto_arch.h.jsing2024-08-111-0/+21
| | | | | | | | 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@
* Move camellia to primary Makefile.jsing2024-03-291-4/+1
| | | | These files are now built on all platforms.
* Move aes_core.c to the primary Makefile.jsing2024-03-291-6/+1

* Move wp_block.c to the primary Makefile.jsing2024-03-291-3/+1
| | | | This is now built on all platforms.
* Merge aes_cbc.c into aes.c now that aes_cbc.c is used on all platforms.jsing2024-03-281-2/+2

* Move des sources to primary Makefile.jsing2024-03-281-3/+1
| | | | | Now that all platforms use a C des implementation, move it to the primary Makefile.
* Consolidate rc4 code.jsing2024-03-271-2/+2
| | | | Discussed with tb@
* Move bf_enc.c to the primary Makefile.jsing2024-03-271-3/+1
| | | | | 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@
* Sprinkle a few BTI instructions into the arm64 assembly files and passkettenis2023-04-052-1/+8
| | | | | | -mmark-bti-property to indicate those now have BTI support. ok jsing@, deraadt@
* Remove the now empty bn_asm.c.jsing2023-01-311-2/+1
| | | | | | 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.
* spelling fixes; from paul tagliamontejmc2022-12-261-3/+3
| | | | | | | i removed the arithmetics -> arithmetic changes, as i felt they were not clearly correct ok tb

* Start disentangling armv7 and aarch64 codetb2022-03-234-2/+196
| | | | | | | | | 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
