  "message": "Improve crypto/digest/md32_common.h mechanism.\n\nThe documentation in md32_common.h is now (more) correct with respect\nto the most important details of the layout of |HASH_CTX|. The\ndocumentation explaining why sha512.c doesn\u0027t use md32_common.h is now\nmore accurate as well.\n\nBefore, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer\nto the |HASH_CTX| and the assembly language implementations tool a\npointer to the hash state |h| member of |HASH_CTX|. (This worked\nbecause |h| is always the first member of |HASH_CTX|.) Now, the C\nimplementations take a pointer directly to |h| too.\n\nThe definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to\nbe consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash\nstate in an array. This will break source compatibility with any\nexternal code that accesses the hash state directly, but will not\naffect binary compatibility.\n\nThe second parameter of |HASH_BLOCK_DATA_ORDER| is now of type\n|const uint8_t *|; previously it was |void *| and all implementations\nhad a |uint8_t *data| variable to access it as an array of bytes.\n\nThis change paves the way for future refactorings such as automatically\ngenerating the |*_Init| functions and/or sharing one I-U-F\nimplementation across all digest algorithms.\n\nChange-Id: I30513bb40b5f1d2c8932551d54073c35484b3f8b\nReviewed-on: https://boringssl-review.googlesource.com/6401\nReviewed-by: Adam Langley \u003cagl@google.com\u003e\n",
