The EVP_PKEY methods for CMAC and HMAC needed a rework, although it wasn't much change apart from name changes. This also meant that EVP_PKEY_new_CMAC_key() needed an adjustment. (the possibility to rewrite this function to work with any MAC is yet to be explored) Reviewed-by:

pkey_test_ctrl() was designed for parsing values, not for using in test runs. Relying on its returned value when it returned 1 even for control errors made it particularly useless for mac_test_run(). Here, it gets replaced with a MAC specific control function, that parses values the same way but is designed for use in a _run() rather than a _parse() function. This uncovers a SipHash test with an invalid control that wasn't caught properly. After all, that stanza is supposed to test that invalid control values do generate an error. Now we catch that.

We made the build of foo.obj depend on foo.d, meaning the latter gets built first. Unfortunately, the way the compiler works, we are forced to redirect all output to foo.d, meaning that if the source contains an error, the build fails without showing those errors. We therefore remove the dependency and force the build of foo.d to always happen after build of foo.obj. Reviewed-by:

These functions are generalizations of EVP_PKEY_CTX_str2ctrl() and EVP_PKEY_CTX_hex2ctrl(). They will parse the value, and then pass the parsed result and length to a callback that knows exactly how to pass them on to a main _ctrl function, along with a context structure pointer. Reviewed-by:

If a MAC isn't available as an EVP_MAC, the MAC test falls back to the corresponding EVP_PKEY method. Reviewed-by:

The MAC EVP_PKEY implementations are currently implemented for each MAC. However, with the EVP_MAC API, only one such implementation is needed. This implementation takes into account the differences between HMAC and CMAC implementations, and observes that all other current MAC implementations seem to follow the HMAC model. Reviewed-by:

We currently implement EVP MAC methods as EVP_PKEY methods. This change creates a separate EVP API for MACs, to replace the current EVP_PKEY ones. A note about this EVP API and how it interfaces with underlying MAC implementations: Other EVP APIs pass the EVP API context down to implementations, and it can be observed that the implementations use the pointer to their own private data almost exclusively. The EVP_MAC API deviates from that pattern by passing the pointer to the implementation's private data directly, and thereby deny the implementations access to the EVP_MAC context structure. This change is made to provide a clearer separation between the EVP library itself and the implementations of its supported algorithm classes. Reviewed-by:

The Name Constraints extension contains GeneralSubtree values indicating included or excluded subtrees. It is defined as: GeneralSubtree ::= SEQUENCE { base GeneralName, minimum [0] BaseDistance DEFAULT 0, maximum [1] BaseDistance OPTIONAL } RFC 5280 further specifies: Within this profile, the minimum and maximum fields are not used with any name forms, thus, the minimum MUST be zero, and maximum MUST be absent. Because the minimum fields has DEFAULT 0, and certificates should be encoded using DER, the situation where minimum = 0 occurs in a certificate should not arise. Nevertheless, it does arise. For example, I have seen certificates issued by Microsoft programs that contain GeneralSubtree values encoded thus. Enhance the Name Constraints matching routine to handle the case where minimum is specified. If present, it must be zero. The maximum field remains prohibited.

In commit 820e414d (pr #5247) the summary output of the Configure command was optimized towards instructing people how to create issue reports. It turned out that the wording of this message can confuse new OpenSSL users and make them think that they are seeing an error message. This commit makes the summary output start with a success to prevent a misunderstanding. Also it gives more hints to new OpenSSL users. Reviewed-by:

Commit 5b4cb385 (#7382) introduced a bug which had the effect that RAND_add()/RAND_seed() failed for buffer sizes less than 32 bytes. The reason was that now the added random data was used exlusively as entropy source for reseeding. When the random input was too short or contained not enough entropy, the DRBG failed without querying the available entropy sources. This commit makes drbg_add() act smarter: it checks the entropy requirements explicitely. If the random input fails this check, it won't be added as entropy input, but only as additional data. More precisely, the behaviour depends on whether an os entropy source was configured (which is the default on most os): - If an os entropy source is avaible then we declare the buffer content as additional data by setting randomness to zero and trigger a regular reseeding. - If no os entropy source is available, a reseeding will fail inevitably. So drbg_add() uses a trick to mix the buffer contents into the DRBG state without forcing a reseeding: it generates a dummy random byte, using the buffer content as additional data.

When building shared libraries on Windows, we had a clash between 'libcrypto.lib' the static routine library and 'libcrypto.lib' the import library. We now change it so the static versions of our libraries get '_static' appended to their names. These will never get installed, but can still be used for our internal purposes, such as internal tests. When building non-shared, the renaming mechanism doesn't come into play. In that case, the static libraries 'libcrypto.lib' and 'libssl.lib' are installed, just as always. Fixes #7492 Reviewed-by:

NIST has updated their guidelines in appendix D of SP 800-56B rev2 (draft) providing a formula for the number of security bits it terms of the length of the RSA key. This is an implementation of this formula using fixed point arithmetic. For integers 1 .. 100,000 it rounds down to the next smaller 8 bit strength 270 times. It never errs to the high side. None of the rounded values occur near any of the commonly selected lengths. Reviewed-by:
