32 hoursbn_ffdh: unifdef HAVE_RFC7919_PRIMEStb1-8/+1
33 hoursbn_const: add RFC 7919 primestb2-2/+300
There is no intention to expose these via public API or to use them in TLS. For now these will only be used for short-circuiting pointless expensive computations in DH_check(). ok beck
33 hoursScapy special for DH_check()tb1-2/+60
The latest release of Scapy calls DH_check() on all the well-known Diffie-Hellman parameters for RFCs 2409, 3526, and 7919. It does this via pyca/cryptography at startup. Every single time. This is obviously very expensive, due to our 64 MR rounds (which are complete overkill now that we have BPSW). Instead of pondering the ideal number of rounds for BPSW with FFDH, simply skip the check if the parameter matches a well-known prime. These are known to be safe primes, so we can skip those super-expensive and pointless checks without any risk. This is only done for the public dh->p parameter. It could be further optimized, but with the follow-up commit adding the RFC 7919 primes this reduces the startup time to what it was before Scapy 2.7.0: < 1s. Reverting from 64 MR rounds to BN_check_primes rounds, we would still have ~8s startup time without this optimization, which isn't great for an interactive tool. Clearly, it's not entirely our fault, it's also Scapy and cryptography that do something ... suboptimal, but I think we're better off if DH_check() isn't a complete DoS vector. If you're using non-standard parameters with FFDH, you deserve it. We could consider adding a flag for non-well-known p and thus making DH_check() indicate failure for candidate primes larger than, say, 4k. https://github.com/pyca/cryptography/issues/14048 ok beck kenjiro

An update to the test vectors adds tests which verifies that the API correctly rejects some inputs.
5 daysWhile almost all the libc locks are taken and released in the sameguenther3-1/+85
libc call, flockfile() and ftrylockfile() can be called when single-threaded and then--while 'holding' the lock--the process can create another thread, resulting in a broken state. Have the f{lock,trylock,unlock}file() APIs *always* do real locking so the exposed state is always consistent. ok dlg@
6 daysRewrite ec_point_cmp()tb1-59/+97
This removes some complications due to handling the fast path for affine points and general points at the same time. The result is a bit more code but both paths should be much easier to follow. ok jsing kenjiro
6 daysmlkem: fix mklem_{generate_key,encap}_external_entropy() declarationstb1-5/+3
The prototypes used sized arrays appropriate only for MLKEM768 while the declarations used pointers. For some reason clang doesn't flag this but gcc does. In any case it was wrong. The callers of these functions check that they pass in the correct size. Which is weird but the mlkem directory has an unbelievable amount of mess and bad code. found by/ok jsing
6 daysmlkem: garbage collect the unusd mlkem_{generate_key,encap}()tb2-58/+2
These are flagged by more recent gcc since declarations and definitions don't match (sized array vs pointer). Also an array was checked for NULL. found by/ok jsing

Make life easier for portable by providing LIBRESSL_USE_.*_ASSEMBLY defines, which enable/disable assembly for a specific algorithm. This means that selected platforms can include the assembly files and specify a define, rather than having to try to patch the crypto_arch.h headers. Discussed with tb@

10 daysstack.c: avoid arithmetic on pointers to voidtb1-2/+2
In stack.c r1.34 I converted one 'char *' too many to 'void *', thereby relying on a gcc/clang extension which interprets the fictional void type as a type of size 1 (that's what the stack code wants, fortunately). As pointed out in the link below, -Wpointer-arith would have caught this: https://gcc.gnu.org/onlinedocs/gcc/Pointer-Arith.html MSVC flags this as follows: D:\a\portable\portable\crypto\stack\stack.c(211,23): error C2036: 'const void *': unknown size [D:\a\portable\portable\build\crypto\crypto_obj.vcxproj]. Pull in workaround from the portable repo which undoes the char * -> void * conversion. ok jsing millert

13 daysMore asn1t.h cleanuptb1-58/+88
This converts more macros to C99 initializers. Rename flags and tags arguments by appending val because they collide with the field names. The remainder are whitespace changes. ok kenjiro
2026-01-09asn1t.h: add C99 initializers for some ASN.1 templatestb1-155/+195
This is a first pass at tidying up the unsightly mess that is asn1t.h. For better or worse, we have expanded the macros internally, and in base only rpki-client uses the templates. They are generally rarely used. Fortunately. Having C99 initializers helps a lot with debugging templated ASN.1 by combining cc -E with clang-format. They make the macros more readable, look tidier and help with grep. ok kenjiro

2026-01-07Fix ASN1_ADB_END macro, make it compatible with OpenSSLtb1-4/+3
In asn1t.h r1.18 (commit 9b72422d) I removed the app_items member from ASN1_ADB and failed to fix up the ASN1_ADB_END() macro that populates the ASN1_ADB. This means ASN1_ADB_END() tried to initialize one member too many and would thus cause a compilation failure, so nobody uses this with LibreSSL. Internally, we have expanded all its uses. We could leave it broken or fix it up. Take the opportunity to add an unused adb_cb() argument instead, making the macro invocation compatible with OpenSSL. ok jsing kenjiro

2026-01-04i2c_ASN1_BIT_STRING() vs ASN1_STRING_FLAG_BITS_LEFTtb2-13/+10
A nasty quirk in the bit string handling is that the serialization produced by i2d_ASN1_BIT_STRING() depends on whether the the magic ASN1_STRING_FLAG_BITS_LEFT is set. If ASN1_STRING_FLAG_BITS_LEFT is set, the number of unused bits is carried in a->flags & 0x07 and the remainder of the bit string is in a->data. This is terrible and undocumented but handled correctly. If ASN1_STRING_FLAG_BITS_LEFT is not set, all trailing zero bits are (intended to be) chopped off with all sorts of hilarious side effects. I broke this quite thoroughly when I incorrectly ported an overflow check from BoringSSL in: https://github.com/openbsd/src/commit/f81cc285d2aed8b36615119a306533696f3eb66c The result is that we currently return ret = a->length + 1 for both NULL and non-NULL pp. The calls to asn1_ex_i2c() in asn1_i2d_ex_primitive() thus report consistent lengths back, making it succeed. asn1_i2d_ex_primitive() therefore skips a->length + 1 bytes, while i2c_ASN1_BIT_STRING() only overwrites len + 1 bytes, which are possibly fewer. So a caller passing in an output buffer containing garbage (malloc) will get some of that garbage back in the encoding. Further, i2c_ASN1_BIT_STRING() also advances that pointer by the possibly reduced len + 1, but that fortunately doesn't matter since that's an effect local to asn1_ex_i2c(), the only caller of i2c_ASN1_BIT_STRING(). The last bit is that the current behavior may set bogus unused bits coming from the scanning backward madness. I added such an example in the parent commit. The fix is simple: use len after the truncation effect was established, not the original a->length, turning this commit into what my backport should have been. This fixes the two currently failing regress tests, so remove expected failure marker again. ok jsing kenjiro
2026-01-04asn1basic: add missing test from BoringSSL's test suitetb1-1/+32
This is another test that fails due to the bug in i2c_ASN1_BIT_STRING().
2026-01-04asn1basic: switch test to expect correct encodingtb2-4/+6
This test fails, so mark the asn1basic test as an expected failure
2026-01-04asn1basic: add example showing current bogus encodingtb1-1/+38
There is a bug in i2c_ASN1_BIT_STRING() resulting in nonsense encoding of some BIT STRINGs with trailing zeroes if ASN1_STRING_FLAG_BITS_LEFT is not set (a rare corner case). This test currently passes when it shouldn't.
2026-01-04i2c_ASN1_BIT_STRING(): zap nonsensical commenttb1-2/+2
The /* should not happen */ happens if a->data is all zeroes (where there used to be an OOB access a few years back), which is a legitimate BIT STRING, so this is just nonsense. ok jsing kenjiro

2026-01-02Unexport ASN1_LONG_UNDEFtb2-7/+8
This is another one of these weird magic values that nothing outside of libcrypto uses. Fix a confusing comment in long_i2c() while there. The skipping behavior is used in particular for omitting the optional length value in the non-standard OpenSSL-specific DHparam() ASN.1 encoding. ok jsing kenjiro

2026-01-01mlkem: clear a few (pointers to) secretstb2-13/+47
The ML-KEM code is doing a pretty poor job at cleaning up secrets it no longer needs. This commit clears a few stack-based arrays containing secrets or not obviously public information and stack-based structs containing pointers to secrets. ok jsing kenjiro
