crypto: ansi_cprng - Remove unused ansi_cprng algorithm

2025-11-22T02:04:50+00:00

Remove ansi_cprng, since it's obsolete and unused, as confirmed at https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/ This was originally added in 2008, apparently as a FIPS approved random number generator. Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around. Suggested-by: Herbert Xu Cc: Haotian Zhang Cc: Neil Horman Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: polyval - Remove the polyval crypto_shash

Remove polyval support from crypto_shash. It no longer has any user now that the HCTR2 code uses the POLYVAL library instead. Reviewed-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20251109234726.638437-8-ebiggers@kernel.org Signed-off-by: Eric Biggers

crypto: sha3 - Reimplement using library API

2025-11-06T04:30:51+00:00

Replace sha3_generic.c with a new file sha3.c which implements the SHA-3 crypto_shash algorithms on top of the SHA-3 library API. Change the driver name suffix from "-generic" to "-lib" to reflect that these algorithms now just use the (possibly arch-optimized) library. This closely mirrors crypto/{md5,sha1,sha256,sha512,blake2b}.c. Implement export_core and import_core, since crypto/hmac.c expects these to be present. (Note that there is no security purpose in wrapping SHA-3 with HMAC. HMAC was designed for older algorithms that don't resist length extension attacks. But since someone could be using "hmac(sha3-*)" via crypto_shash anyway, keep supporting it for now.)

crypto: blake2b - Reimplement using library API

Replace blake2b_generic.c with a new file blake2b.c which implements the BLAKE2b crypto_shash algorithms on top of the BLAKE2b library API. Change the driver name suffix from "-generic" to "-lib" to reflect that these algorithms now just use the (possibly arch-optimized) library. This closely mirrors crypto/{md5,sha1,sha256,sha512}.c. Remove include/crypto/internal/blake2b.h since it is no longer used. Likewise, remove struct blake2b_state from include/crypto/blake2b.h. Omit support for import_core and export_core, since there are no legacy drivers that need these for these algorithms.

crypto: curve25519 - Remove unused kpp support

2025-09-06T21:45:49+00:00

Curve25519 has both a library API and a crypto_kpp API. However, the crypto_kpp API for Curve25519 had no users outside crypto/testmgr.c. I.e., no non-test code ever passed "curve25519" to crypto_alloc_kpp(). Remove this unused code. We'll instead focus on the Curve25519 library API (), which is a simpler and easier-to-use API and is the API that is actually being used.

Pull crypto library updates from Eric Biggers: "This is the main crypto library pull request for 6.17. The main focus this cycle is on reorganizing the SHA-1 and SHA-2 code, providing high-quality library APIs for SHA-1 and SHA-2 including HMAC support, and establishing conventions for lib/crypto/ going forward: - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares most of the SHA-512 code) into lib/crypto/. This includes both the generic and architecture-optimized code. Greatly simplify how the architecture-optimized code is integrated. Add an easy-to-use library API for each SHA variant, including HMAC support. Finally, reimplement the crypto_shash support on top of the library API. - Apply the same reorganization to the SHA-256 code (and also SHA-224 which shares most of the SHA-256 code). This is a somewhat smaller change, due to my earlier work on SHA-256. But this brings in all the same additional improvements that I made for SHA-1 and SHA-512. There are also some smaller changes: - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For these algorithms it's just a move, not a full reorganization yet. - Fix the MIPS chacha-core.S to build with the clang assembler. - Fix the Poly1305 functions to work in all contexts. - Fix a performance regression in the x86_64 Poly1305 code. - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code. Note that since the new organization of the SHA code is much simpler, the diffstat of this pull request is negative, despite the addition of new fully-documented library APIs for multiple SHA and HMAC-SHA variants. These APIs will allow further simplifications across the kernel as users start using them instead of the old-school crypto API. (I've already written a lot of such conversion patches, removing over 1000 more lines of code. But most of those will target 6.18 or later)" * tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (67 commits) lib/crypto: arm64/sha512-ce: Drop compatibility macros for older binutils lib/crypto: x86/sha1-ni: Convert to use rounds macros lib/crypto: x86/sha1-ni: Minor optimizations and cleanup crypto: sha1 - Remove sha1_base.h lib/crypto: x86/sha1: Migrate optimized code into library lib/crypto: sparc/sha1: Migrate optimized code into library lib/crypto: s390/sha1: Migrate optimized code into library lib/crypto: powerpc/sha1: Migrate optimized code into library lib/crypto: mips/sha1: Migrate optimized code into library lib/crypto: arm64/sha1: Migrate optimized code into library lib/crypto: arm/sha1: Migrate optimized code into library crypto: sha1 - Use same state format as legacy drivers crypto: sha1 - Wrap library and add HMAC support lib/crypto: sha1: Add HMAC support lib/crypto: sha1: Add SHA-1 library functions lib/crypto: sha1: Rename sha1_init() to sha1_init_raw() crypto: x86/sha1 - Rename conflicting symbol lib/crypto: sha2: Add hmac_sha*_init_usingrawkey() lib/crypto: arm/poly1305: Remove unneeded empty weak function lib/crypto: x86/poly1305: Fix performance regression on short messages ...

crypto: sha1 - Wrap library and add HMAC support

2025-07-14T15:59:20+00:00

Like I did for crypto/sha512.c, rework crypto/sha1_generic.c (renamed to crypto/sha1.c) to simply wrap the normal library functions instead of accessing the low-level block function directly. Also add support for HMAC-SHA1, again just wrapping the library functions. Since the replacement crypto_shash algorithms are implemented using the (potentially arch-optimized) library functions, give them driver names ending with "-lib" rather than "-generic". Update crypto/testmgr.c and an odd driver to take this change in driver name into account. Note: to see the diff from crypto/sha1_generic.c to crypto/sha1.c, view this commit with 'git show -M10'.

lib/crypto: hash_info: Move hash_info.c into lib/crypto/

2025-07-08T19:03:44+00:00

crypto/hash_info.c just contains a couple of arrays that map HASH_ALGO_* algorithm IDs to properties of those algorithms. It is compiled only when CRYPTO_HASH_INFO=y, but currently CRYPTO_HASH_INFO depends on CRYPTO. Since this can be useful without the old-school crypto API, move it into lib/crypto/ so that it no longer depends on CRYPTO. This eliminates the need for FS_VERITY to select CRYPTO after it's been converted to use lib/crypto/.
