2020-01-06Don't store an HMAC key for longer than we needMatt Caswell
The HMAC_CTX structure stores the original key in case the ctx is reused without changing the key. However, HMAC_Init_ex() checks its parameters such that the only code path where the stored key is ever used is in the case where HMAC_Init_ex is called with a NULL key and an explicit md is provided which is the same as the md that was provided previously. But in that case we can actually reuse the pre-digested key that we calculated last time, so we can refactor the code not to use the stored key at all. With that refactor done it is no longer necessary to store the key in the ctx at all. This means that long running ctx's will not keep the key in memory for any longer than required. Note though that the digested key *is* still kept in memory for the duration of the life of the ctx.

2019-09-28Fix header file include guard namesDr. Matthias St. Pierre
Make the include guards consistent by renaming them systematically according to the naming conventions below For the public header files (in the 'include/openssl' directory), the guard names try to match the path specified in the include directives, with all letters converted to upper case and '/' and '.' replaced by '_'. For the private header files files, an extra 'OSSL_' is added as prefix. Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/9333)
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.
