  "message": "Clean up PKCS5_PBKDF2_HMAC.\n\nThis was a mess. HMAC_CTX_copy_ex would avoid having to cleanup and init\nthe HMAC_CTX repeatedly, but even that is unnecessary. hctx_tpl was just\nto reuse the key. Instead, HMAC_CTX already can be reset with the same\nkey. (Alas, with a slightly odd API, but so it goes.) Do that, and use\ngoto err to cleanup the error-handling.\n\nThanks to upstream\u0027s b98530d6e09f4cb34c791b8840e936c1fc1467cf for\ndrawing attention to this. (Though we\u0027ve diverged significantly from\nupstream with all the heap-allocated bits, so I didn\u0027t use the change\nitself.)\n\nWhile I\u0027m here, tidy up some variable names and cite the newer RFC.\n\nChange-Id: Ic1259f46b7c5a14dc341b8cee385be5508ac4daf\nReviewed-on: https://boringssl-review.googlesource.com/14605\nReviewed-by: Steven Valdez \u003csvaldez@google.com\u003e\nCommit-Queue: Steven Valdez \u003csvaldez@google.com\u003e\nCQ-Verified: CQ bot account: commit-bot@chromium.org \u003ccommit-bot@chromium.org\u003e\n",
