pointers to provider size algorithm contexts. Fixes #14284 The gettable_ctx_params methods were confusingly passing a 'provctx' and a provider context which are completely different objects. Some objects such as EVP_KDF used 'data' while others such as EVP_MD used 'provctx'. For libcrypto this 'ctx' is an opaque ptr returned when a providers algorithm implementation creates an internal context using a new_ctx() method. Hence the new name 'algctx'.

2019-09-28Reorganize local header filesDr. Matthias St. Pierre
Apart from public and internal header files, there is a third type called local header files, which are located next to source files in the source directory. Currently, they have different suffixes like '*_lcl.h', '*_local.h', or '*_int.h' This commit changes the different suffixes to '*_local.h' uniformly. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)
2019-09-28Reorganize private crypto header filesDr. Matthias St. Pierre
Currently, there are two different directories which contain internal header files of libcrypto which are meant to be shared internally: While header files in 'include/internal' are intended to be shared between libcrypto and libssl, the files in 'crypto/include/internal' are intended to be shared inside libcrypto only. To make things complicated, the include search path is set up in such a way that the directive #include "internal/file.h" could refer to a file in either of these two directoroes. This makes it necessary in some cases to add a '_int.h' suffix to some files to resolve this ambiguity: #include "internal/file.h" # located in 'include/internal' #include "internal/file_int.h" # located in 'crypto/include/internal' This commit moves the private crypto headers from 'crypto/include/internal' to 'include/crypto' As a result, the include directives become unambiguous #include "internal/file.h" # located in 'include/internal' #include "crypto/file.h" # located in 'include/crypto' hence the superfluous '_int.h' suffixes can be stripped. The files 'store_int.h' and 'store.h' need to be treated specially; they are joined into a single file.

2019-08-24Get rid of the diversity of names for MAC parametersRichard Levitte
The EVP_PKEY MAC implementations had a diversity of controls that were really the same thing. We did reproduce that for the provider based MACs, but are changing our minds on this. Instead of that, we now use one parameter name for passing the name of the underlying ciphers or digests to a MAC implementation, "cipher" and "digest", and one parameter name for passing the output size of the MAC, "size". Then we leave it to the EVP_PKEY->EVP_MAC bridge to translate "md" to "digest", and "digestsize" to "size".

2019-08-16Rename ctx_{get,set}_params to {get,set}_ctx_paramsRichard Levitte
Recently, we added dispatched functions to get parameter descriptions, and those for operation context parameters ended up being called something_gettable_ctx_params and something_settable_ctx_params. The corresponding dispatched functions to actually perform parameter transfers were previously called something_ctx_get_params and something_ctx_set_params, which doesn't quite match, so we rename them to something_get_ctx_params and something_set_ctx_params. An argument in favor of this name change is English, where you'd rather say something like "set the context parameters". This only change the libcrypto <-> provider interface.

2019-08-15Prepare EVP_MAC infrastructure for moving all MACs to providersRichard Levitte
Quite a few adaptations are needed, most prominently the added code to allow provider based MACs. As part of this, all the old information functions are gone, except for EVP_MAC_name(). Some of them will reappear later, for example EVP_MAC_do_all() in some form. MACs by EVP_PKEY was particularly difficult to deal with, as they need to allocate and deallocate EVP_MAC_CTXs "under the hood", and thereby implicitly fetch the corresponding EVP_MAC. This means that EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count may need to be incremented and decremented as part of the allocation or deallocation of the EVP_MAC_CTX. It may be that other provider based EVP operation types may need to be handled in a similar manner.

2018-10-29Add EVP_MAC APIRichard Levitte
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.
