[edk2-devel] [staging/crypto-new-api PATCH] CryptoPkg: Fix issues from crypto code review.
Posted by yi1 li 1 year, 9 months ago
Details:
1. Some APIs need more detail comment.
2. Correct BnRShift() param order.
3. Remove unsecure ECC curve from GroupToNid().
4. Add full public key validating procedures to EcDhDeriveSecret().

Re: [edk2-devel] [staging/crypto-new-api PATCH] CryptoPkg: Fix issues from crypto code review.
Posted by Tan, Ming 1 year, 9 months ago
Yi:
  I have the following suggestion.
  1. Suggest to split the patch to several patchs. Special the code which modify the logical.
  2. Change the commit title, "fix the issues the code review" sounds like show that the reviewers did not good job at before 😉

  BR/Tan Ming.
